OSAKA —Panasonic says it has developed the world’s first write-once Blu-ray discs (BD-R) with 6X writing speed. The new discs will be available in Japan with both 25GB and 50GB capacities in this July.
Panasonic, which introduced the world’s first dual-layer 1X BD-RE Blu-ray Disc in 2004, 2X BD-R/RE discs in 2006, and 4X BD-R disc in 2007, is now launching the world’s first 6X BD-R to meet consumer demand to write and read large amounts of data at a higher speed. The new 6X discs have a maximum data transfer speed of 216 mbps, which is 20% faster than that of 16X DVD-R discs. This transfer speed, along with the discs’ high capacity, allows consumers to use these discs for a variety of applications such as storing high definition video or backing up PC data.
The new discs have a wide power margin at any writing speeds from 1X to 6X. This enables high-quality recording, even if the drive’s laser power fluctuates, resulting in greater overall drive compatibility.
