In addition, the new drive features a system that automatically adjusts the laser characteristics in real time, in order to deliver the optimum recording conditions. Noise and distortion signals are also filtered from the read-out signal when accessing 50GB BD-R media, allowing reading of the discs even at speeds of 4x.
The drive is build according to the recently released "Blu-ray Disc Recordable Format Part 1 Version 1.2" standard.
The new drive is able to write 25GB of data in 23 minutes, and 50GB in 43 minutes, using a 4x CLV writing strategy.
Panasonic also expected to release its first 25GB BD-R media for 4x recording by the end of the month. 50GB BD-Rs should be expected later this September.
Currently, Hitachi LG Data Storage is also offering 4x recording for BD-R media, aiming at 6x with its upcoming GGW-H20L BD burner (July). Pioneer is also expected to offer 4x BD-R writing with its second generation of BD drives.
