Pioneer develops 400GB optical disc

Pioneer 400GB Optical

Pioneer this morning promised to expand removable storage with one of the largest confirmed optical storage capacities available. By cutting back on the potential for interference from different layers on a given disc, the electronics maker says it can manufacture readable discs with 16 layers; at 25GB per layer, this equates to 400GB on a single disc.

The format is also fundamentally similar to Blu-ray, according to Pioneer. As both the per-layer size (25GB) and reading lens behave in a similar way, the new disc format is effectively compatible with regular Blu-ray discs.

The Japanese company hasn't said when it expects to commercialize its 16-layer discs but says its discovery should become "necessary" in the near future; Pioneer is one of the primary supporters of Blu-ray and makes both computer-based drives as well as dedicated movie players. [via Impress]

    Not Gonna Buy It Until

    I am not gonna buy this thing until the data storage capacity of this thing is increased to at least 1.2 terabytes.....

    I have way too much data to back up and to have to use at least 4 of these disks would be way too expensive!

    I can only imagine what one of these is going to cost. A single-layer BRD is out of my league right now much less a 16-layer.

    the cost (sure to be several hundred bucks) what about the 2 months needed to burn 400G of data?

    If it gets scratched, do you lose all 400gb of data? or will it go back to the days of hard outer cases like MO disks?
