OT; 1TB Blu-Ray Disk

Since the Blu-Ray post have had such "lively" discussions in the past, this may be of interest to some of you.

I would certainly like a 1TB removable disk medium. Hopefully it's not pie-in-the-sky dreams and will not cost a fortune.

I wonder just exactly how long it might take to burn a 1TB disk?? Can you imagine a few scratches in the wrong place and losing all that info?

Another wonderment (on the same page) is the intro of the 300 gig 3D HD Holographic disc.
HHHMMMMMM. When can I shoot, capture, edit, burn, 3D holographic media?

The holographic disc has nothing to do with holographic images. It's a method of storing data, nothing else.

Regarding the 1TB disc, it says the data rate is 100MB/sec. Also, I'm sure the data is well error protected and it may also come in a caddy to further protect it.

1TB at 100Mb/s comes out to a bit over 22 hours, not counting tracking and sector format information. Probably will end up a few hours longer because of that.

The fluid lens is the secret to "depth" reading and writing. I have posted before about fluid lens moving into disk and camera technology. Micro-fluid lens on the ccds will create a new technology in the area of DOF. The available to rapidly change DOF by electro charge, just can't be matched by mech means.

"1TB at 100Mb/s comes out to a bit over 22 hours" overheating of media will the "limiting" factor over 100M in commercial products, I would think.

If they didn't have a misprint in the article it says "The I/O rate is said to be around 100MB/sec". If this is true to standard usage, this would actually mean 100 megaBytes instead of bits. This would be on par with a ATA-100 hard drive. Not accounting for formatting overhead, lead-in, etc, that would be a theoretical best of 2.77 hours.

I'm not sure of the typical burn rate of blu-ray but, IRL, a standard DVD+R (4.7GB) can burn in about 5 minutes (depending on burner) so that gets back up the 17+ hour mark.

I really hope 100MB is right.

"I really hope 100MB is right." Yes, that would be nice. But the 100MB read, for commercial users, would probably required a multi-receptor sensor behind the lens, ie a 1024vs1024 "pixel" sensor that is extremely fast and buffered(3d capture). This could simulate multi track reads in some hard disk systems.
