Panasonic Starts Pilot Production of 50-GIGABYTE Blu-ray Discs

Another + for the Blu-Ray Disc Supporters.. New Dual-Layer Spin Coat Technology Doubles Disc Capacity.

Panasonic has modified its existing pilot production line for single-layer Blu-ray Discs, called BD-ROM, so that it is able to replicate dual-layer BD-ROM discs with 50 gigabytes (GB) of storage capacity.

The doubling of BD-ROM disc storage capacity is enabled by spin coating technologies developed by Panasonic that create two recorded layers on a single side of a Blu-ray Disc. In the process, readily available inexpensive UV curable resins are used in the creation of the space layer, cover layer and hard-coat, resulting in a reduction in disc replication costs. Video and other data is then embedded in the layers for playback later using a blue laser-equipped Blu-ray Disc player, recorder or BD-ROM drive-equipped PC.
