There may not be many Blu-ray high-definition movies available yet, but Sony Electronics is urging PC owners to make their own: The BWU-100A internal drive can record up to 50GB of data -- enough for four hours of 1080i video from an HDV camcorder -- on BD-R (write once) or BD-RE (rewritable) media. Burning a 25GB (single-layer) Blu-ray disc takes approximately 50 minutes.

The ATAPI drive also reads and writes 4.7GB DVD±R and ±RW discs, along with 8.5GB dual-layer DVD+R discs and CDs. CyberLink's BD Solution software handles capturing, authoring, editing, and burning high-definition personal content, as well as "down-converting" HD video to standard definition for burning to DVDs. Sony says the 5.25-inch drive will ship in August for about $750.
