Pioneer announced 400GB optical discs

Tip: Click here to update all your PC's outdated driversPioneer has developed a 16-layer read-only optical disc which it claims can store 400GB of data.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.
Multi-layered discs have been difficult to develop because 'crosstalk' from adjacent layers and transmission loss mean that getting a stable signal from the disc is often nearly impossible.
Pioneer achieved stability in the playback of recorded signals by employing a wide-range spherical aberration compensator and light-receiving element that can read out weak signals at a high signal-to-noise ratio in the optical pick-up mechanism.
The huge capacity of these discs means that the new technology will be best suited for applications such large volume data archiving, rather than consumer use.
Pioneer will present the details of this research at the International Symposium on Optical Memory and Optical Data Storage 2008 in Hawaii on 13 July.

good thing is based on evolution of technology it will only get faster/smaller physical
size/bigger logical size. i bet by 2010 we will be able to fit at least 5tb in our wallet
while at the same time forgetting that our wallet is worth so much. lol.
that's a lot of space on an optical media but i think optical media should be replaced.
optical media is very slow. then there is the issue of durability (ie scratches, etc.)
i can't remember the last time i burned a cd or dvd. my dvd player in my car
takes sd media and i just copy my music to that. when i get the chance to upgrade i'll
have a hard drive in there that holds all my music. dvd's i just watch from what's
stored on my computer. optical media is becoming obsolete.
i realize it
won't be marketed towards the average consumer but even at that capacity it's not
practical. most businesses use high capacity tape drives or raid configurations for
backup purposes. i just fail to see the use of a 400gb optical media. blu-ray is slow
enough. i can't imagine how long it takes to search a 400gb optical media.
the move to high capacity memory cards are more practical, durable and faster. personally
i think pioneer just wasted it's time and money with r&d of this media.
being that it's listed as "read only"...
this officially marks the death of blu-ray.
discs seem old now it seems that everything is on a flash drive or hard drive- its
quicker to access data and more reliable, and you can read and write to them, i don't see
the point in a 400gb disc you might as well have a multi-terrabyte usb hard drive if it's
for company use- imagine losing 400gb of important data from a scratch on it- you would
have to make backups, so why not just use a hard drive? i haven't bothered wasting money
on blu-ray or hd-dvd yet, i don't know how long they will last for or if new technology
will come out so i don't see the point in spending hundreds on a blu ray player-
everything today seems to be progressing towards hard drives and streaming network now, i
will only shell out if a solid storage device comes out that i know will last years and
years
how did those movies get onto your computer? hmmmm??? o, thats right, they were ripped
from a dvd most likely. o, and where has that music on the sd card come from? o gee, idk,
maybe a fukin cd! think before u speak random nonsense lik "errr, cds and dvds are, err,
umm, obsolete. umm.." retard
