Pioneer Promises 400GB Optical Discs

Posted by timothy on from the place-for-their-stuff dept.

schliz writes "Pioneer has developed a 16-layer read-only optical disc which it claims can store 400GB of data. The per-layer capacity is 25GB, the same as that of a Blu-ray Disc, and the multilayer technology will also be applicable to multilayer recordable discs."

    Anyone care to venture how long it would take to burn such disc, if it is loaded full?

    Frankly, given the track record of optical formats, I'd be surprised if this ever makes it out of the laboratory, especially given the fact that it has so many layers. With DVD a lot of production companies basically gave up on the dual sided dual layer discs because the yield on 4 layer disks was so bad. Getting a good yield on a 25 layer disc is either an achievement worthy of talking about over the disc, or it's a bunch of lies and marketing hype.

    Too bad InPhase already has had a holographic disk of that capacity for a while now plus a write speed that blows this media away.

    Call me a snob if you like, that does not change the fact I can tell the difference very quicly on my 56" HDTV between HD content and DVD content, especialy when the HD content was recorded with a HD camera, not upconverted from film.
    To me the diffence is as drastic as going from VHS to DVD.
    Some people just do not care, and that is fine.
    My Dad can sit in front of his 15 year old tv and the picture has a red ghosting hue to it, and drives me nuts but when I tell him he should get a HDTV, he just tells me he likes the one he has just fine, this is a guy that watches every sporting event on TV, and that content is mostly shot with HD cameras, so he would really benefit from the upgrade, but would he care? NO

    I have no clue what "artifacts" you are talking about

    I can attest that Hollywood studios are very serious about making their newest Blu-rays "artifact free". We're talking MPEG-4 AVC/H.264 at 25 Mbps, which (speaking as a HDTV guy) is way overkill for most eyes. Consider that terrestrial HDTV is =19 Mbps MPEG-2 and what you see on cable or DBS is probably compressed down from that. I'm pretty happy delivering 14 Mbps H.264 HDTV to stations for high-quality prime-time network use.

    In post-production houses, there is now this position called the "compressionist" who uses semi-automated systems to compress each scene 10 or 20 different ways with different parameters to ensure the best compression. There are built in PSNR measurement, MOS estimation, as well as the human eye looking over all this. And it costs a lot of money....
