TDK working on 200GB Blu-ray disc

*************************************************

TDK this week confirmed its plan to develop a Blu-ray disc with a storage capacity of 200GB. Let's put that into perspective - how big is the hard drive in the PC or laptop you're currently using? It's around three times the size of the storage available on my current machine.

If successful, the company's R&D team will produce a disc with four times the capacity of today's biggest BDs and double the size of protoype next-generation BD-Rs TDK has already shown off. TDK unveiled a 100GB prototype in May 2005, which contained four data-storage layers, is recordable and supports a write speed of up to 216Mbps, double that of 50GB BD-Rs.

TDK: Ok, we're done with the 200GB recordable Blu-Ray

That was fast. It took 'em years to develop recordable DVDs, then another couple more for the dual layer variety, but now but a few weeks after TDK announced their hard workin' intentions to develop 8-layer 200GB recordable Blu-ray discs, they've got it bagged. Balls to the fact that we still don't have the players; the interesting thing about these discs, however, is that the data isn't stored on thin layers of dye, no no. Apparently when each layer of bismuth peroxide and germanium oxide is heated to 690K by laser, microscopic air bubbles form and create the bits we've come to know and obsess over. Oh sure, these discs are probably going to be horrendously expensive in the beginning, but isn't it nice to know we're already good to go on capacities large enough to archive years of home movies?

Sony prohibits their licensees from manufacturing HD-DVD equipment. That issue will have to be resolved.Enforcement of patents is sometimes flaky in the asian markets. If sony doesn't come to the table places like south korea and thailand will probably wink at infringements.

It isn't like here in the United States of lAwyers.

Problem solved.

My understanding of the situation is -

Sony owns the Blu-Ray technology, and licenses it to a consortium of manufacturers.

One of the conditions Sony imposes on the licensees is that they cannot manufacture equipment for the competing HD-DVD technology.

I don't think the restriction applies to content providers (i.e., movie studios), who can sell discs in both formats if they choose to do so.

Blu-Ray is the better format, but I'm concerned that Sony's restrictions are anti-competitive. A dual-mode player would be a good thing.

December 13, 2005
TDK Corporation has commenced shipments of mass-production samples of so-called bare-type (i.e., cartridge-less) versions of its BD-R (write-once type) and BD-RE (rewritable type) Blu-ray Discs. The four new products include the BD-R25 (single-side, single-layer, 25GB) and BD-R50 (single-side, dual-layer, 50GB) write-once types and BD-RE25 (single-side, single-layer, 25GB) and BD-RE50 (single-side, dual-layer, 50GB) rewritable types.

Mass production at TDK's Chikumagawa Techno Factory, which specializes in optical discs, will commence upon issue of licensing for the bare disc.

With today's digital society and its burgeoning volume of data, as well as the rapid diffusion of digital high-definition broadcasting, demand has grown for discs that achieve larger capacity and higher-speed recording while at the same time are easy to use. The BD-R and BD-RE introduced by TDK are bare (cartridge-less) discs that fully satisfy these needs for larger capacity and higher-speed recording with high reliability.

In April 2003, TDK had launched sales of the BD-RE120N (rewritable type, enclosed-type cartridge) for recording use. This was followed in November 2004 by the BD-RE135N (rewritable type, open-type cartridge), which received acclaim for its stunning high-definition images.

At the Data Storage Expo in June 2005 and CEATEC in October, TDK unveiled prototypes of cartridge-less, single-sided, single-layer 25GB and dual-layer 50GB Blu-ray Discs, which demonstrated that from the technological standpoint such products had been perfected.
For the Blu-ray Disc, which achieves significantly higher density recording, scratches or dirt can have fatal consequences to the data, so it was initially introduced utilizing a protective cartridge. The BD-R and BD-RE Blu-ray Discs launched this time make use of DURABIS 2, TDK's originally developed hard coating technology. This achieves a recording surface with extremely high resistance to scratches and dirt (particularly fingerprint smudges), thus enabling anxiety-free use of a cartridge-less disc.

For the forming of the cover layer above the disc's recording layer, an original high-precision spin coating is utilized, realizing smoothness at the nano-level while achieving stabilized recording and playback characteristics.

The BD-R write-once type, moreover, makes use of an inorganic material in the recording layer, entirely different from the organic dye used in previous types of write-once type discs. Because the recording layer is not affected by light, it realizes a disc with outstanding archivability. Furthermore, the BD-RE rewritable type utilizes a high-sensitivity phase-change material that realizes stabilized characteristics, in the form of a low error rate, even after 10,000 overwrites.

In addition, the single-sided, dual-layer disc realizing 50GB capacity harnesses high-precision stacking technology resulting from years of work at optical disc development, to achieve precision forming of its respective functioning layers. The upper layer (Layer 1) and lower layer (Layer 0) are combined in terms of high sensitivity and recording layer transparency ratio, realizing stabilized recording and playback characteristics.

The commitment of TDK's advanced optical disc technology has resulted in creation of the world's first 25GB and 50GB high-capacity discs capable of 2X recording speed. TDK is confident that the BD-R and BD-RE, freed from the confines of a cartridge, will offer their large capacities with greater facility, thus greatly expanding the potential of optical recording.

Main features of BD-R and BD-RE Blu-ray Disc
  1. Use of DURABIS 2 coating designed for bare (cartridge-less) Blu-ray Discs provides significantly greater resistance to scratches and dirt (particularly fingerprint smudges), ensuring safe use even without a cartridge.
    Since the area of the laser spot on the Blu-ray Disc is small (about one-fifth that of the DVD), scratches or dirt on the recording surface can have a much more severe effect than on DVDs, causing interference with the irradiation of the laser beam and, in worst cases, even loss of irreplaceable data. For the recording surfaces on the BD-R and BD-RE, the DURABIS 2 coating specially developed for the bare Blu-ray Disc is utilized. Along with significantly higher resistance to scratches, it is also extremely resistant to dirt (particularly fingerprint smudges), ensuring safe use even without a protective cartridge. (Figs. 1, 2 and 3.)

  2. Original high-precision spin coating creates a cover layer with nano-level smoothness, realizing stabilized recording and playback.
    The Blu-ray Disc is constructed of a 1.1mm thick substrate with a 0.1mm thick cover layer. For the laser beam to penetrate the cover layer to the recording layer, the cover layer assumes the function of a lens, so to speak. For this reason, in the Blu-ray Disc, which uses a blue-violet laser with significantly shorter wave length, the precision and smoothness of the cover layer, from the standpoint of accurate laser irradiation, is extremely important. To form this cover layer, TDK utilizes an originally developed high-precision spin coating. The thickness precision is controlled at the nano-level, and an outstanding cover layer with extreme smoothness is formed. As a result, the load on the focus servo circuit used to correct laser beam position is reduced, making possible more stabilized recording and playback. (Figs. 4, 5)

  3. The BD-R write-once type utilizes a recording layer of inorganic material. Since it is unaffected by exposure to light, it boasts outstanding archivability.
    Previous types of write-once type discs such as the CD-R, DVD-R and others utilized organic dye for their recording layer. The BD-R write-once type is based on a completely new concept for the recording layer utilizing a two-layer structure composed of silicon (Si) and copper alloy (Cu) inorganic materials. When heated by the recording laser beam, these melt and the Si and Cu alloy become a composite forming recording marks. Because the material is inorganic, it is not affected by light, thus realizing a disc with outstandingly high reliability in terms of archivability. (Fig. 6)

  4. The rewritable BD-RE utilizes a high-sensitivity phase-change material in the recording layer that realizes stabilized characteristics even after as many as 10,000 rewrites.
    In the BD-RE rewritable type disc, exclusively designed high-sensitivity phase change recording material and a layer structure for high-density recording are utilized to realize excellent recording/playback characteristics and overwrite characteristics. Even after 10,000 rewrites, stabilized characteristics are realized. (Fig. 7)

  5. High-precision stacking technology precisely overlays disc layers having respective functions. Stabilized characteristics on the upper (Layer 1) and lower (Layer 0) are realized in a single-sided, dual-layer (50GB) disc.
    The single-sided, dual-layer disc realizing a tremendous 50GB capacity was achieved through the high-precision stacking technology developed from TDK's years of accumulated experience in optical discs. The respective recording layers, Layers 0 and 1, each composed of recording and dielectric layers, plus a spacer layer and a cover layer, are formed with high precision in thickness that totals 0.1mm (100μm). By this, both Layer 0 and Layer 1 are matched in terms of precision and recording layer transparency ratio, realizing stabilized recording and playback characteristics. (Figs. 8, 9)

The diagram at the left is a measurement of the thickness of the cover layer of the Blu-ray Disc from the inner (20mm from the center) to the outer sections (60mm from the center). Here it can be seen that with the previous method of spin coating, the inner section was thinner and the outer section thicker, whereas TDK's new spin coating method results in the forming of a uniform, high-precision coating 100 μm thick.

The cover layer of the TDK Blu-ray Disc formed by the original spin coating method realizes precision on the nanometer level. This is why the blue-violet laser can achieve accurate irradiation of the recording layer.

Blu-ray vs HD DVD: State of the Division

Blu-ray
vs HD DVD: State of the Union Division

Well, as far as HD DVD vs. Blu-ray goes, it looks like we've pretty much passed the point of no return now; with each passing day it seems less and less likely that a compromise will be reached on a next-gen format. The ongoing peace talks between the two camps, which have been on-again, off-again for months now, seem to have finally dissolved. It's disappointing, but however you feel about the fact that the HD DVD and Blu-ray factions squandered countless chances to make it right and come together, it looks like in just a few short months they're going to be duking it out mano a mano right in our livingrooms. There may not be a lot we can do to fight back — apart from refusing to adopt either format out of sheer spite of their pigheadedness — but no matter what we might as well at least arm ourselves with the knowledge necessary to understand the nature of the situation at hand.

Here's the background:

Philips's development of the Laserdisc in 1969 yielded many of the technologies Sony carried over and adopted when they partnered with Philips to create a little something called the CD way back in '79. Both companies were hard at work together once again in the early 1990s on a new high-density disc called the MultiMedia Compact Disc (MMCD—original name, guys), but their format was eventually more or less abandoned in favor of Toshiba's competing Super Density Disc (SD), which had the vast majority of backers at the time, such as Hitachi, Matsushita (Panasonic), Mitsubishi, Pioneer, Thomson, and Time Warner.

The two factions cut a deal, brokered by IBM president Lou Gerstner, on a new format: DVD. Toshiba wound up on top after the dust settled in 1995/1996, and Sony and Philips, who weren't cut in on the standard (and royalties) nearly as much as they'd have liked, immediately started work on a next gen system. The Professional Disc for DATA (aka PDD or ProDATA), which was based on an optical disc system Sony had already been developing in the side, would eventually become the Blu-ray disc. Toshiba, not to be outdone by the pair, also started work on a next gen system, the Advanced Optical Disc, which eventually evolved into the HD DVD. After thirty-five years of optical audio/video disc development we're back where we were years ago: two money-grubbing factions fighting each other and threatening to wreak havoc on the consumer electronics industry. Apparently history really does repeat itself.

So here's the technical nitty gritty before we drop the graphs n' charts on ya. Both systems use the same kind of 405nm wavelength blue-violet laser, but their optics differ in two ways. Since the Blu-ray disc has a tighter track pitch (the single thread of data that spirals from the inside of the disc all the way out-think grooves on a 12-inch vinyl single vs. an Elvis Costello full-length album), it can hold more pits (those microscopic 0s and 1s) on the same size disc as HD DVD even with a laser of the same wavelength.

The differing track pitch of the Blu-ray disc makes its pickup apertures differ, however - 0.65 for HD DVD vs. 0.85 for Blu-ray - thus also making the two pickups technically incompatible despite using lasers of the same type. HD DVD discs also have a different surface layer (the clear plastic layer on the surface of the data - what you get fingerprints and scratches on) from Blu-ray discs. HD DVD use a 0.6 mm-thick surface layer, the same as DVD, while Blu-ray has a much smaller 0.1mm layer to help enable the laser to focus with that 0.85 aperture.

Herein lies the issues associated with the higher cost of Blu-ray discs. This thinner surface layer is what makes the discs cost more; because Blu-ray discs do not share the same surface layer thickness of DVDs, costly production facilities must be modified or replaced in order to produce the discs. A special hard coating must also be applied to Blu-ray discs, so their surface is sufficiently resilient enough to protect the data a mere 0.1mm beneath - this also drives the cost up. The added benefit of keeping the data layer closer to the surface, however, is more room for extra layers.

Still with us? No? Blu-ray discs are more expensive, but hold more data - there, that's all.

So now that you know why Blu-ray discs cost more and why Sony/Philips and Toshiba are all harshing on one another so much, we can get to the really important stuff: the numbers, and who's supporting who.
