Turner Testing Holographic Storage 174
Izmunuti writes "An article in ComputerWorld describes tests by Turner Entertainment of a holographic storage system from InPhase Technologies as a possible replacement for magnetic tape for storing their movies and other programs for playback and broadcast. The article states that each holographic disk holds 300 GBytes." Even more impressive is the cost per terabyte estimated for just a few years down the road.

HDTV Screen Size is 1920 * 1080 = 2,073,600 so that is the number of pixels on the highest quality HDTV
2,073,600 Pixels * 30 FPS (Frames per second for DVD Playback) = 62,208,000 Pixels / Second
Pixel is 24 bits * 62,208,000 Pixels / Second = 1,492,992,000 Bits / Second
They are 8 bits in a byte so 1,492,992,000 / 8 = 186,624,000 Bytes / second
1024 Bytes in a Kilo Byte 186,624,000 Bytes/second / 1024 = 182,250 KB/Seconond
1024 Kilo Bytes in a Mega Byte = 177 Mbs per second. So for screens of random data where no compression can take place that is correct.
But the tough part to prove because I don't have the numbers is the average rate of data compression per movie. If we are able to keep compression at an average of 1/6 then we could do it. CNET.com states that HDTV Requires 19.25Mbps for HDTD transmission so I guess it does do the trick.

The number you get is not 177 Mbs per second, it is 177 MBps (Mega Bytes per second as you say), whyle the number from CNet is 19.25 Mbps (mega bits per second), and it refers to MPEG2 compression of the stream.
In this case there is plenty of bandwidth available because 19.25 Mbps = 2.40 MBps < 27 MBps. In any case, MPEG4 compression can do much lower bitrates for HDTV video, but I strongly doubt that they will use any kind of lossy compression for their stored archive video.

On the other hand, reading speed can be tremendous. You get a full page of data for each reading operation. Some people will say you can read "at the speed of light", because all it takes to extract a page of data is to let diffract a laser beam through the holographic media. This is not completely true, as you still have to convert the data from its original optical form to an electronic form suitable for computer. This is usually done using arrays of CCD or CMOS detectors, and their speed is the limiting factor when reading data.
If I can get a hand on several documents that I know to be hiding somewhere on my computer, I will post actual speed figures which might give you a better idea of the typical transfer rates.
Re:Holographic? (Score:5, Informative)
I know that a CMOS detector integration speed of 1ms has been reached several years ago on holographic RAM (I am not talking here about holographic disks). As the integration speed is the limiting factor during the readout, that means you roughly read 1000 pages of data per second.
Usually, these pages of data are arrays of 1024x1024 values, coded on 256 different brighness levels (therefore equivalent to 8 bits, or one byte). That means you can get a reading speed of 1GB/s on that technology.
However, I think most of the research nowadays is turned towards holographic disks, because they are more suited to the "write once slowly, read many times quickly" behaviour of holographic memory. The main problem here is to find (or create) an holographic material suitable for this usage. So far, data density has been much lower in holographic disks than in holographic RAM because of this issue.

This is a common misconception. MTBF is not very useful when you're only talking about a few drives. It's better to use failure rates, since this is how manufacturers compute MTBF anyway. They test 100 drives for 1 year, and 2 fail. That's a failure rate of 2% per year. Then they figure out, from that, how many years would pass at that initial failure rate before all the drives had failed, and take the mean of the lifetimes. Consider this: If two drives each have a 98% probability of surviving the fi

Large backups should not take much more human effort than small backups, the difference should only be computer and drive time. If it does take a lot of effort, make a script or use an automatable backup program, then do something else while the computer does the work for you.

Hard drive prices per unit of storage have dropped about 50% per year, give or take a bit.
(reality check - $80-90 for a 120GB drive was a good price last year at this time, I just got a 250GB drive for $93 last week; in 1987, a 20GB drive was $400, about $20/MB, today, its about $3.72x10-4/MB, about 45% per year)

They use Ultra320SCSI as an electrical interface to the discs. These guys were co-promoting with Maxell in the Maxell booth itself on the media that's in these large cartridges similar to the old MO discs, but larger. The holodiscs themselves were about half an inch thick and were completely transparent, and had excellent archival characteristics and stability (>100 years IIRC). The drives themselves were about the size of a two-drive external SCSI drive box, but fairly long (probably around a foot or slightly longer) and black in color. Media was something like $179 per disc and the drives themselves were $6k-$10k, IIRC. Finally, I asked him why they wouldn't just put the disc into a cube format (read: all your information on your keychain), but he mentioned that the translational control of the cube to read and write the information would be overly complicated electromechanically though it could technically be done.
My guess is that you won't see this technology filter down to the average joe for at least 5-7 years. Hopefully it'll be worth the wait.
