TDK Develops 200GB Blu-Ray Disc.

Yup, great news

TDK Works on 200GB Blu-Ray Media

TDK Corp., a leading maker of recordable media, said Tuesday it was developing technologies that would leave behind its record of the last year and enable Blu-ray discs with 200GB of capacity.

..

A claim about possibility to enable 200GB Blu-ray media is targeted to showcase potential technology excellence of the Blu-ray discs over the competing HD DVD standard, which largest capacity is about 50GB today.

Traditional single-layer DVDs allow consumers to watch movies in 720x480 (NTSC) or 720x576 (PAL) resolution with Dolby Digital audio. The blue-laser discs will provide consumers 1920x1080 resolution as well as DTS or Dolby Digital Plus audio along with some additional interactive features.

Blu-ray and HD DVD formats compete for replacing the DVD standard. HD DVD discs can store up to 15GB on a single layer and up to 30GB on two layers. Its competitor, Blu-ray, can store up to 27GB per single layer and up to 50GB on two layers, but Blu-ray discs are more expensive to produce. The HD DVD is pushed aggressively by Toshiba and NEC as well as being standardized at the DVD Forum, which represents over 230 consumer electronics, information technology, and content companies worldwide. Blu-ray is backed by Sony and Panasonic, which are among the world’s largest makers of electronics. Among Hollywood studios HD is supported by Warner Bros. Studios, New Line Cinema, Paramount Pictures and Universal Pictures, whereas Sony Pictures, Walt Disney, Warner Bros. and Twentieth Century Fox endorse Blu-ray.

Oh yeah !

These TDK 200GB disks are based upon 33 GB per layer. The current 25 & 50 GB disks are 25 GB per layer and the original roadmap had the 200 GB systems at eight layers. Will TDK still be able to push it to eight layers (264-267 GB)?

It's unfortunate Blu-ray did not start out with 33 GB per layer for all versions:
33 GB single layer
66 GB double layer
132 GB quad layer
200 GB six layer
267 GB eight layer (over 31 dual layer DVDs or over 5 years of your favorite TV show in SD)

Will the players/writers/PC drives for these 33 GB per layer disks be backwards compatible with the 25 GB per layer systems/disks?

Will the PS3 be able to read 33GB per layer discs?

I think it probably will, but wanted to be sure.

it probably wont, these 33gb layers are out of the specs, just a proof-of-concept prototype to get media attention. i'd be surprised if we ever hear about them again, let alone see them standartized and in production.

perhaps a (distant) future refinement of the specs could make use of such an increased layer density, but by that time technology would have achieved many other improvements aswell - phase modulation for example, so i'd expect much higher capacity per layer by then. if we haven't moved on to completely different (i.e holographic) storage methods that is.
