Massive data capacity, up to 25GB on one BD-R / BD-RE disc
The LH-2B1S uses the revolutionary blue laser technology instead of the red laser in current optical drives. This technology provides precise laser focus and greatly increases storage capacity. Commercial advertising, studio and catalog photographers, the film industry, and IT managers will greatly benefit from High-Definition (HD) content playback and massive data archiving to reduce physical storage space. The LH-2B1S can store up to 25 GB of data on a single-layer BD disc.
