Sony Buys a Facebook Spinoff to Give New Life to Blu-ray

In other (unrelated) blu-ray news, blu-ray is finally getting a UHD (aka 4K) high dynamic range spec.

For anyone interested, here's a video Facebook released of the system in action:

Quick fact:

Cost of a pack of 50 25GB Blueray Disk: $37.75. That's 3.02¢/GB

Price of 1TB hdd: $47. That's 4.59¢/GB

I am guessing 1TB BR disks are going to be costlier than 25GB ones.

100G BD-R XL triple layer media is already $10-$30 each. Theres supposed to be quad layer media too, but it doesn't seem readily for sale in the us.

Being a niche market item must be pushing the price way up, i doubt its that much more complicated to make than dual layer media.

I didn't see anything about the ease of copying data by stamping it. It seems like making hard copy duplicates easily would be a huge benefit of this as well.
