JAPANESE ELECTRONICS GIANT Sony has developed a quad layer HD DVD storage capacity of 128GB, giving up to four hours of recording.
Sony's own XDCAM Professional Disc line will get this new quad layer burning format, which doubles current generation discs and is over five times faster than single layer discs at 23X. At the moment this XDCAM is write only but at least Sony has also upped the transfer speed so you don't have to sit up all night in front of your PC archiving.
The disc, otherwise known as PFD128QLW, was built with Sony's latest laser and recording techniques. The company claimed its blue-laser technologies and high density recording mechanism made it possible to turn out the 128GB quad-layer disc.
That four hours of HD content recording can only be achieved if users record in MPEG HD422 mode at 50Mbps. Sony reckoned this can be bumped up to 7 hours 50 minutes of content recording in DVCAM mode.
"This new disc's unique combination of large recording capacity and high transfer rate opens a new frontier for this proven professional optical disc format in the area of video file archiving applications," said by Kazutaka Hasegawa, general manager of Sony media and peripherals Europe.
"Its write-once feature positions the media as an excellent option for long-term archiving, especially when you need to protect the original video files against tampering or unintended erasure."
Sony hasn't put a price on it yet. In fact, Sony was way ahead with this announcement because it's not due to ship until summer 2011. A year is a long time in storage disc technology so we'll probably see other vendors offering similar capacities by then. µ
If you change the string "years" into "weeks" in what they claim as the long-term archiving solution lasting period, you have an exact perspective on when you can throw it in the garbage bin.

W.O.R.M stands for:
Write Once Read Many
Any media can be adequately digitized.
The only questions are:
- what level of precision can the human eye/ear discern
- what level of precision can the image/sound be rendered with
If the encoding resolution is more precise than the human can discern, or that the output medium can reproduce, then it is adequate.
Would you record Mozart as only an MP3.
Would you paint the Mona Lisa as only an JPG.
Could you imagine if our eyes could only see in MPG.
Yes, yes and yes. None of these have to be compressed so high that they fail. These were made so that normal media could be compressed, and still be 100% in quality. I can still put a full HD movie on an old DVD disc, and not have ANY difference from the original. If you can't, then you don't know how to do it correctly.
Sounds great, BUT!!
Since larger size can hold more data files, HD video or/and audio time, would it not be advantages to reduce compression and bring back quality rather than quantity.
My understanding of todays generation is not knowing what quality is. Digital replication of an analog input to a storage media is supose to be of higher quality over analog media and not compression formats. Time to reduce compression and bring back quality.
My understanding as to why we need so much processor horsepower is in decoding compressed audio and video.
We did this because we had, at one time, lack of digital storage space.
Today, if people want to compress to a lossy format, go ahead, but now the recording industry's goal should be less conpression.
My understanding of pictures, music and video is it is an art and should retain as much of the original content without having to resort to using a lossy compression.

If the above is the case, then we just reduced our most importent senses in life.
Wourthless!!
As meationed before The goal now is to increase storage size of media to reduce compresion and retain as much as possible of all analog input content.
I hope it's readable too...
... that won't see production. Sometimes I think the optical format manufacturers tease this stuff so they still seem relevant.

The acronym is "W.O.R.M."
"Write optimistically, read maybe".
Either here or at The Reg I believe I did recently read about someone's laboratory hard disk writing technique that unfortunately has no disk reading technique to go with it, so it isn't absolutely ob iously wrong, but, really...
Anyway, to want to re-write a disk, don't you have to finish filling it up first? Could take a while with this one.
