Panasonic has started shipping samples of an ultra-thin Blu-ray disc drive for lightweight notebooks.

The new drive is capable of reading and burning high-definition DVDs in the Blu-ray format. It also supports reading and writing standard DVDs and CDs, and can store 50 Gbytes of content.Panasonic has slimmed down a standard DVD disc drive to 0.28 of an inch thick. Toshiba has said that it plans to release an equally thin drive for reading and writing DVDs in the HD DVD format, which competes with Blu-ray.

Ultra-thin disk drives make it possible for notebook makers to build even lighter and slimmer products. The drives could also find a place in even small ultra-mobile PCs.

Panasonic has other Blu-ray disc drives. Last summer, the company became one of the first to introduce a drive with a 4x writing speed. The latest drive is 2x.
