New Disks hold 1 TB of data

Holographic Versatile Discs (HVD) have the capacity to hold up to 1 terabytes (TB) of information, which is approximately 33x times the capacity of HD-DVD Disks and 20x the capacity of Blu-ray Discs. The HVD also has a transfer rate of 1 Gbit/s.

HVD recording technology records data on discs in the form of laser interference fringes, enabling existing discs the same size as today's DVDs to store as much as one terabyte of data, with a transfer speed of one gigabyte per second (40 times the speed of DVD). This approach is rapidly gaining attention as "a high-capacity, high-speed data storage technology for the age of broadband".

It employs a technique known as collinear holography, whereby two lasers, one red and one blue-green, are collimated in a single beam. The blue-green laser reads data encoded as laser interference fringes from a holographic layer near the top of the disc while the red laser is used to read servo information from a regular CD-style aluminium layer near the bottom. Servo information is used to monitor the position of the read head over the disc, similar to the head, track, and sector information on a conventional hard disk drive. On a CD or DVD this servo information is interspersed amongst the data. A dichroic mirror layer between the holographic data and the servo data reflects the blue-green laser while letting the red laser pass through. This prevents interference from refraction of the blue-green laser off the servo data pits and is an advance over past holographic storage media, which either experienced too much interference, or lacked the servo data entirely, making them incompatible with current CD and DVD drive technology.

Not only that, but HVD seems to be gathering a small following including such companies as:

* CMC Magnetics Corporation
* Fuji Photo Film Co., Ltd.
* Konica Minolta Optical, Inc.
* Mitsubishi Kagaku Media Co., Ltd.
* EMTEC (MPO International)
* Nippon Paint Co., Ltd.
* Optware Corporation
* Pulstec Industrial Co., Ltd.
* Ovalrock
* Software Architects, Inc.
* Toagosei Co., Ltd.

What does everyone think?
Should we really be looking at HD-DVD, and Blu-Ray as the next generation of data storage?

i think that blu-ray and hd should come to an agreement one one technology. it could end up that movies and stuff would come out on 2 standards, and that would be shits for the market

this wont be for everyday consumers. it will be for huge storage solutions. such as offsite backups that some companies use.

at the job I work at we store 160 gigs of compressed stuff daily to tape. and it always grows. so these disks would be very expensive. and aimed towards this market. (a new tape drive we are getting is $9,000)
thats how much these drives will probably cost. or actually more.

yea, that would suck but thats whats gonna happen. im sure sony will buy this software or something and make an entire line of products that ONLY works with these disks and they will be the ONLY ones that can use it. it will just be a glorified PSP.

yeah thats one of the big problems with that. very error prone. a little scratch can knock out a couple of gigs

and thats where sony messes up.

so far to my knowledge they fucked up two good formats, thus being beta and minidisc.

thank you sony.

Wow, amazing shit. I was going to buy an external HD with a terabyte, but then I realized I didn't need quite that much memory.
