Panasonic Corp's Digital AVC Marketing Division will release a rewritable single-sided three-layer Blu-ray disc that is compatible with the Blu-ray Disc Rewritable Format and has a capacity of 100 Gbytes April 15, 2011.
The company claims that it is the world's first rewritable Blu-ray disc with a capacity of 100 Gbytes.
The new product is a 2x-speed recordable Blu-ray disc compatible with the BDXL Part1 Version3, and its capacity is twice as large as that of an existing single-sided two-layer Blu-ray disc (50 Gbytes).
Specifically, it is possible to record about 12 hours of a terrestrial digital TV program in the DR mode (with a transfer rate of 17Mbps) and about eight hours and 40 minutes of a BS digital TV program in the DR mode (with a transfer rate of 24Mbps).
Also, in the HZ mode (15x recording time, transfer rate: 16Mbps) of Panasonic's BDXL-compatible Blu-ray disc recorders that were released in February 2011 and later, it is possible to record about 130 hours of a TV program by using the new disc.
The new Blu-ray disc can be used only with BDXL-compatible recorders. As for Panasonic's products, BDXL-compatible Blu-ray disc recorders that were released in and after September 2010 can be used with the disc.
