The new Blu-Ray DVD disks introduced by the TDK Corporation are the BD-R25, BD-R50, BD-RE25 and BD-RE50. TDK BD-R25 and BD-R50 are “write-once” discs while the other two BD-RE25 and BD-RE50 are the “rewritable” Blu-Ray disks. TDK (BD-R25) is single layered and single sided Blu-Ray disk with capacity of 25GB. TDK (BD-R50) is also single layered and single sided Blu-Ray disk with more recording capacity of 50GB. BD-RE25 is dual layered, single sided Blu-Ray disk having 25GB recording capacity. BD-RE50 is also dual layered, single sided Blu-Ray disk having twice the recording capacity of 50GB.

Initially the Blu-Ray disks used a protected cartridge but now TDK introduced the technology of DURABLES-2 (hard coating) in both the Blu-ray DVD disks of BD-R & BD-RE. So, a recording surface is achieved that is very highly resistant to dirt, scratches and the fingerprint smudges. Therefore, the users can freely use the Blu-Ray DVD disks without any anxiety. Above the recording layer of disk is utilized spin coating of high precision to form the cover layer. So, smoothness is realized at nano level and this ensures stabilized characteristics of playback and recording.

The previous types of write once disks used organic dye while the recording layer of new TDK BD-R Blu-Ray DVD disks use inorganic material. As light does not effect the recording layer, so the disk realizes remarkable achievable. The error rate of BD-RE is has a very low even after overwrites of 10,000 due to the phase change material that is highly sensitive. For achieving functioning layer’s precision forming of the dual layered 50GB Blu-Ray disk, the stacking technology of high precision has been added.

The layer-0 (lower layer) and layer-1 (lower layer) are combined together in terms of recording layer and high sensitivity transparency ratio, ensuring stabilized characteristics of playback and recording. TDK Corporation’s commitment to the advanced technology of optical disk has created the world’s first high capacity Blu-ray DVD disks (25GB & 50GB) with capable recording speed of 2X. BD-R and BD-RE Blu-Ray disks from TDK provide greater facility along with large data storage capacities hence expanding optical recording’s potential.

The other name for Blu-ray disks is “BD disk” which is the optical disk format’s next generation. This disk format was joint introduction by the BDA Blu-ray Disk Association (group of companies that include Dell, HP, JVC, Hitachi, Apple, Mitsubishi, Pioneer, LG, Panasonic, Thomson, Sony, TDK, Philips, Sharp and Samsung). The main purpose for developing this DVD disk format was to enable the HD video’s rewriting, playback and recording and the ability to hold more volume of data.

The Blu-Ray DVD format is more advantageous than the traditional DVD. The latest technology induced in the Blu-Ray disk format enables it to hold data more than 5 times as that of which the DVD can store. The recording capacities of the single layered Blu-Ray disk are 25GB and that of the dual layered disk is 50GB.

The combination of extra data recording capacity and utilization of advanced codec of audio and video provide the consumers the HD High definition experience that is unprecedented. The main difference between the other disk technologies (DVD, DVD-RAM, DVD±RW, and DVD±R) and Blu-Ray disk format is that the blue-violet laser is used in the Blu-Ray while red laser is used in the other formats for the function of reading and writing data onto the disk. That is why it has been given the name of Blu-Ray.

Just while a Decade back, people were using the FLOPPY DISC, things they found were going simple for small data transfers and storage of small files ( max of 1.44 MB). Then came the ERA of Compact Disc ( CD’s ). With the technology of CD ( 700 MB) , there was great turning point to all major industries , large data transfer and storage was possible, but it still lacked the high defination (HD) clarity for audio and Video. Then moving still up in the graph we had powerful turning point towards DVDs ( 4.7 GB). Here high definition was possible but still some or the other factor lacked for extreme high definition Videos.

But with the technology of BLU-RAY disc, all was possible. Blu-ray, also known as Blu-ray Disc (BD), is the name of a next-generation optical disc format jointly developed by the Blu-ray Disc Association (BDA), a group of the world’s leading consumer electronics, personal computer and media manufacturers (including Apple, Dell, Hitachi, HP, JVC, LG, Mitsubishi, Panasonic, Pioneer, Philips, Samsung, Sharp, Sony, TDK and Thomson). The format was developed to enable recording, rewriting and playback of high-definition video (HD), as well as storing large amounts of data. The format offers more than five times the storage capacity of traditional DVDs and can hold up to 25GB on a single-layer disc and 50GB on a dual-layer disc. This extra capacity combined with the use of advanced video and audio codecs will offer consumers an unprecedented HD experience.

With the advent of a new generation of high density discs to replace DVDs, it is easy for consumers to be confused about which format to upgrade to. The two competing formats, Blu-Ray and HD DVD, both offer a significant upgrade in video and audio quality; but as standalone players for both formats can retail for several hundreds of pounds, it is understandable that consumers do not want to end up buying the new Betamax.

In terms of technical performance both formats are similar, and show little discernible difference to the average consumer. A dual-layer Blu-Ray disc offers 50GB of storage space, compared to 30GB on a dual-layer HD DVD disc, but as of yet, only 40% of Blu-Ray releases are dual-layer, with the remaining 60% being single-layer discs utilising 25GB of storage space. Still, even when comparing a 50GB Blu-Ray disc with a 30GB HD DVD, the difference to consumers will be minimal. Both formats support the MPEG-2, VC-1, and H.264 formats for video compression, and Dolby Digital, PCM, and DTS for audio compression. As a result, this battle of formats is going to be waged mainly via the titles available and the price and quality of players.

Initially, both formats were supported by all of the major studios, but as different studios have different stakes in the two formats, major studios started to drop formats. For example, Sony, owner of Columbia and TriStar Pictures, is one of the major developers of the Blu-Ray format, and has decided to drop HD DVD for its releases. Thus, Spiderman 3 is only available for Blu-Ray, something which will surely irk Spidey-loving HD DVD adopters. Releases on both formats tend to be priced similarly, a little more than their standard DVD counterparts.

When it comes to the players, a lot has happened, even in the past year. The first generation of standalone players for the two formats, released last year by Toshiba, Samsung and Panasonic, were seen as pricey and more aimed at early adopters than the general public, and have already been discontinued.

The latest generation of players have generally been seen as more value for money, but the smart money says to look elsewhere for now. Sony decided to include Blu-Ray playing capability for the Playstation 3 Console, which was undoubtedly a wise business move. It means the 5 million current PS3 owners already have a Blu-Ray player and gives those unsure which format to switch to an incentive to buy a PS3 as a low-risk option – even if Blu-Ray does go the way of the Betamax, they still have a state-of-the-art gaming console. In a similar tactic, consumers can now buy an HD DVD drive for the Xbox 360, which can also connect to a high-end PC via a USB connection.

As for now, Blu-Ray has the edge in the format war. Figures by Nielsen VideoScan, Gfk and the Nikkei, show that Blu-Ray is outselling HD DVDs at a ratio of 2 to 1 in the US and Europe and a ratio of 9 to 1 in Japan. This does not mean the battle is over just yet – a lot can still happen, particularly if Nintendo should decide to throw their hat in the ring by announcing an external player for either format for the Wii (a drive for normal DVDs will be released next year).

Hopefully at the end of the format war, the ultimate benefactor will be customers and not the corporations, but until then alternatives to standalone players can provide an affordable way to enjoy the best video and audio quality available for home viewing.

Today’s news from Toshiba, that it was throwing in the towel in the high definition format battle and will no longer manufacture HD DVDs, transformed the speculation and rumors into fact. Now we have to figure what the effect will be for consumers and retailers.

Toshiba’s stock soared 5.7% Monday as investors cheered the likely decision to lessen the losses from a protracted battle with Blu-Ray. Microsoft is still mum about the effect of losing the HD DVD format offered as an add on player for the XBox 360. Retailers are applauding the move hoping that consumers wary of buying an obsolete HD DVD player will buy into the new Blu-Ray technology. Consumers that have already bought the HD DVD players will assuredly be able to buy HD DVDs really cheap as retailers will have to dump their existing titles. Many of these titles will be offered on the internet for some time. I can see where E-bay will get a boost from selling these titles.

If everybody remembers Sony lost the last format war when Sony’s Betamax went head to head with VHS and lost. The reason it lost that format was the same reason it won this round – storage capacity. The new Blu-Ray Disc has twice the storage capacity of the HD-DVD. Current storage capacity is 25GB on a single-layer disc and 50GB on a dual-layer disc, and a 200GB is being developed. The other reason VHS was better than Betamax was the speed of rewind and fast forward. In today’s digital world picture quality depends on bit rates. HDTV broadcast can reach up to 10 Megabits per second while Blu-Ray can reach up to 48 Mbps. This can make a really big difference in action movies. Sony also had a better marketing strategy this time when it coupled it with the PlayStation 3, providing a relatively cheap player combined with a very popular video game console.

The next generation video game console battle between Microsoft’s XBox 360 and Sony’s Playstation 3 just wrote a new chapter. PlayStation 3 has become the big winner because they Xbox 360 used the HD DVD player. Even though Microsoft has some big catching up to do, they were smart enough to offer the HD DVD player as an add on to the XBox 360. Where Microsoft will go from here is unclear. Will the next Xbox incorporate Blu-Ray technology or will they abandon a player in favor of a 250GB hard drive?

Will the next technology incorporate a solid state drive? SSDs currently have a 64GB storage capacity with no moving parts. They have a much faster data access with more reliability and use less power. Right now SSDs are not cheap. The MacBook Air uses the 64GB SSD with a price tag of $1,300 higher than the same unit with a 80GB hard drive. But remember that it was not that long ago that a 256MB USB flash drive cost more than today’s 16GB USB flash drive. The next video format very well could include a solid state memory device.

With technology improving everyday, you quickly start to notice that not only can you still use CD or DVDs to do CD duplication, DVD duplication or even CD packaging and DVD packaging, but you can now use new formats to store or sell programs and more.

It is actually now possible to use Blu-Ray and high definition technology to do all that. Those new technology can store even more data than the normal CD or DVD that would be used for CD replication, DVD replication and the others.

We hear a lot about Blu-Ray discs and high definition but what is it really.

The Blu-Ray disc is the next generation of optical disc format developed to enable recording, playback or rewriting of high-definition video most commonly known as HD, as well as storing a large amount of data. Whereas a DVD has a storage capacity of up to 8.5GB, a Blu-Ray would have a storage capacity of up to 50 GB and a high definition DVD would have a storage capacity of up to 30GB which make those types of storage hugely interesting.

While discs like DVDs and CDs use a red laser to write and read the data, the new Blu-Ray format actually uses a blue-violet laser. Using a blue-violet laser instead of a red laser means that the laser has a shorter wavelength which makes it possible to focus the laser dot with even better accuracy, thus allowing data to be packed more compactly and stored in less space which obviously mean a greater storage capacity.

The Blu-Ray technology is supported by around two hundred of the world’s leading computers, consumer electronics, video game and music companies for the moment and this number is meant to grow with the years. The format is even supported by all Hollywood studios as the successor to the DVDs we all use for the moment. Interestingly, High Definition DVDs have not been used much due to the growing success of Blu-Ray discs, especially since you can store much more data on a Blu-Ray disc than on a high definition DVD.

Even if the Blu-Ray and high definition formats are not widely in use at the moment, they will certainly be in the coming years as soon as the technology becomes better known by the consumers around the world. So next time you want to get DVD or CD duplication or even DVD packaging or CD packaging done, think about using Blu-Ray discs instead.

There has been much hype about the “war” between Sony’s Blu-Ray technology and the HD-DVD technology of Toshiba. Both are high definition digital video disc formats but then factor that will reveal the outcome of the war is what format will be most appealing to the consumers.

Since the formats appeared in the market space (which the did almost simultaneously), both have been a though sell to consumers because so far it hasn’t been clear which one will come out on top on the format war. Naturally both the Sony Company and that of Toshiba promotes their own standard heavily through both advertising and through partnerships.

Repeating the Beta-max vs. VHS war

However it is generally agreed that there can be only one format that will come out on top, and with memories of the format war between the VHS and Beta-max video tapes no more than a few decades ago, most consumers are waiting to see which standard will win the battle. They are afraid of getting burned by investing in technology that will soon be obsolete.

The funny part is that it is the customers that will determine the outcome but many await the outcome before investing. Luckily there are some people that will always invest and the major companies are spending millions and millions to add trust to their particular brand or technology.

How to evoke confidence

A central dilemma to both Sony and Toshiba is how to evoke enough confidence in their own formats in order to convince consumers that their format will be around in the long run and not end up like the Beta-max video did two decades ago. The format question is really only a matter of perception by the consumers on which technology that will win the war.

If consumers perceive one format to be more likely to be around five years from now, they will buy software titles and movie in that format and the machines to play that particular format. When the movie studios and software companies see that consumers like that format, be it Blu-ray or HD-DVD, they will publish more titles in that format. When consumers see more a lot more titles in one format than the other, they will gain even more confidence in that format and the “good spiral” has begun which will eventually determine who will win the format war.

Blu-ray backed by Twentieth Century Fox

Recently the major company Twentieth Century Fox has announced that it will release numerous movie titles in the Blu-ray format and that it thereby backs the format of Sony. Releasing between five to ten titles per month, this is a major show of confidence in Blu-ray’s potential to be the winning format.

The steady stream of new titles should provide anyone who is thinking of buying a Blu-ray player or who already owns one with plenty of new movies to look forward to over the next year.

The direction towards the Blu-ray technology is good news for TV and computer technology in general because of the technical advantages that Blu-ray has over the HD-DVD format.

Superior quality doesn’t always win

One of the main benefits comes from the fact that even though they rely on similar types of laser technology and are both about the same physical size, a HD-DVD discs can only store fifteen gigabytes on each side for a total of only thirty gigabytes while a Blu-ray disc can store up to twenty five gigabytes of data on each side for a total of fifty gigabytes. Unfortunately, the consumer’s decisions aren’t always in favor of the superior technology.
