Pioneer Promises 400GB Optical Discs
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."
Good thing we all updated early to the blu-ray player, when something is about to come along to blow it out of the water, right at about the time when DVDs are reaching the point where people need more than 2-3 DVDs for games/movies (which is the point at which CDs were phased out, and floppy disks).
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.
I read the internet for the articles.
With so many layers, I wonder if the useful lifespan of the disk is shorter than a conventional DVD. The obvious application for these discs is backing up servers and home storage drives.
How is that a bad thing considering SONY have released a useful disk format. You're suggesting that they'd buy a load of companies and then not bother to look into any interesting tech that those companies had been researching? Blu-ray is theoretically capable of holding just as much as these disks if SONY can work out how to do multi-layer work effectively, as Pioneer claim to have done. I'd expect SONY are either close on their heels in R&D terms, or could just license the tech.
The main difference between these 2 formats are that SONYs was out in the market over 2 years ago, and Pioneer has yet to get this tech out of the lab. 2 years ago, a 50GB optical format (dual layer blu-ray) was quite useful, and it still is today. Blu-ray also has rewritable disks in the market.
Really, I don't see what use in the extremely-mild-conspiracy type comment serves.. companies like google and MS always buy out other companies and assimilate their tech. In some cases that can be negative, but in other cases it leads to some great products.
BTW, Wikipedia points out that FMD died because one of their demonstrations was proven to be a hoax. I presume they did have some working tech though because DMD is being developed by a company who acquired Constellation 3D's patents.
which is totally what she said
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.

A 500 GB HDD costs less than a single one of these discs, is reliable, rewritable a million times, lasts decades if properly stored, is already available, is faster, and requires no fancy hardware.
I'm curious as to on what you base your statement that a 500 GB HDD will last decades. Can you cite a study on the long-term storage reliability of modern hard disk designs? In my personal experience, disks which have sat unused for several years sometimes don't spin up. They're not designed for that.
I'll also point out that the equipment needed to read an ST-506 hard disk -- introduced circa 1980, thus "decades" -- would likely be somewhat hard to find and integrate into a modern operation. It might not be "fancy hardware", but the end result (high cost) is the same.
I'm not dismissing the use of hard disks for archiving in general; I just find some of your claims dubious.
One thing that seems to be true is that storage is getting cheaper and bigger all the time. Thus for some applications, it may actually be cost-effective to keep all your archives online (disks spinning), with redundancy, and simply upgrade to newer, larger drives as old ones fail. Capacity keeps growing for new data, and old data keeps getting copied to new media. That eliminates the concerns about keeping equipment around to read old media. As an added bonus, everything is online all the time.

I do not like Microsoft. Remove them from my email address.
Essentially wouldn't this be the same as having an 8 platter HD (aside from the slower moving read head)? This could easily outperfom a 2-4 platter Hard drive, no?
