Pioneer says it is making a 16-layer optical disk with a capacity of 400 gigabytes (GB).
The announcement came in a press release this morning.
The new disk looks just like a DVD or Blu-ray (BD), and like a Blu-ray, packs 25 GB in each layer, an innovation made possible by the use of blue lasers. The difference in the new Pioneer disk is the number of layers. With 16 blue-laser layers, the new disk can hold 16 times as much data.
Pioneer says its new device can read so many layers because of signal-processing enhancements that allow it to more accurately separate the layers.
The new Pioneer disk is otherwise the same as Blu-ray, so Pioneer hopes to be able to make players that can play both its new disk format and Blu-ray.
The biggest challenge for the new high-capacity format could be finding digital products big enough to need the extra capacity. If one Blu-Ray holds three seasons of a television series, will one 400 GB disk hold 48 seasons? One way or another, expanding the capacity of the familiar 12-centimeter optical disk should help keep the idea of a physical digital product relevant.
Pioneer says it will present more details of its new technology next week.
