50gigs storage space right away or delayed? - Blu-ray Forum

m1a1 · 01-10-2006, 05:48 AM

i would like to know if i should be as excited as i am?
with Bd tech is it going to allow for up to 50gigs storage space right away? or is it going to be delayed and used for home theater only for awhile?

It depends on your level of excitement! Providing it's not a health risk stay excited. Although the pioneer (to be released some time around March) is only single layer (25GB). Panasonic are expected to release theirs by March or sooner, if the specs have not changed 50 real BIG ones. The disk manfacturers are apparently readying dual layer "blanks", so hopefully before mid year there will be a number to choose from.

Yes they will be expensive to start with - but expect prices to fall quickly.

Note that the Pioneer BDR-101a PC drive can play dual layer (50GB) discs but can only write to single layer BDRs/BDREs (and DVDs). Pioneer expect to launch a fully 50GB capable drive in Q2/Q3 ...

thanks, i thought my excitement wasnt going to waste.
i work with tons of video and have been waiting for away toback it up safely.

... You'll also like the fact that TDK (for one) produces BDRs using non-organic "dyes" which are light-insensitive and guaranteed to last much longer than traditonal organic dye based CDRs, DVDRs, BDRs and HD DVDRs ... :^>

James:

The information you provide is really exciting for archive and storage. Do you have a link where I can understand the projected shelf life of the TDK BDRs?

Hi Douglas,

TDK are using a copper alloy/silicon composite to form the data "marks" on its BDR25s, BDR50s and planned BDR100s, by melting and mixing a silicon layer and a copper alloy one. The press releases indicate that the enhanced precision and stability of the (inorganic) recording layers had already allowed 6x recording in the labs. by spring 2005, with very low jitter (typically around 4%). This of course puts less strain on the servo-mechanisms and can potentially lead to better sound and picture quality. With the inorganic recording layer also not being light sensitive, they further make comments such as ideal for archival purposes, outstanding archivability, exceptionally suitable for long term archival, but do not currently provide any projected lifetime figures and comparisons (detailed or otherwise) - see:

http://www.tdk.com/tecpress/20060103_bdship_ces.html and
http://www.blu-raydisc.com/assets/do...0606-13019.pdf

I have asked for such information several times since early 2005 - but obviously this is a new technology which has until recently been in development. However, now that the first generation inorganic recording technology based discs are about to be shipped I would expect that some basic longevity figures will soon be released - followed by more detailed results, as the promise of this technology is clearly likely to be of considerable interest to archivists. Certainly a light-safe recording process has the potential to form a major advance in archival of data - and to significantly change the way in which data is archived and managed.

Dear James:

Thank you for the infomration. I will be looking for more information as it becomes available.

Douglas.

Thanks both for the good news

However, is there any reason why they never used it for CD/DVD in the past? And does LD use an organic dye?
