Sony sent out a press release this afternoon, announcing their upcoming Blu-ray Disc based products. Along with their first Blu-ray Disc player, the BDP-S1, Sony plans to offer both desktop and notebook computers equipped with Blu-ray Disc drives. Sony has also provided some information on their new internal Blu-ray writer, the BWU-100A.

The BWU-100A, an aftermarket internal Blu-ray Disc drive for computer use, will support recording of 25GB and 50GB BD-R (write once) or BD-RE (rewritable) discs at 2X max speed. It is capable of burning a full 25GB disc in about 30 minutes. The drive will also support recording of standard single layer 4.7GB DVD+R/+RW, Double/Dual Layer 8.5GB DVD+R, DVD-RAM and CD-R/-RW media, making it a true all-in-one "tri-mode" recorder/reader.

The new drive can be installed in a standard half-height computer bay with a parallel ATAPI (P-ATA) interface. Comprehensive authoring software will be included for capturing, editing, and burning high-definition personal content captured by an HDV format camcorder, keeping the video in native 1080i HD format for playback on a Blu-ray Disc player. Video can also be "down-converted" to standard-definition (SD) resolution for burning onto a DVD disc.
While Sony plans to ship the BDP-S1 Blu-ray Disc player and the VAIO RC desktop computer in July, we have not heard when the BWU-100A will be available or how much it will cost. As we find out more, we'll let you know. In the mean time, Sony's entire press release can be found here.
