Mose Baer Blu-ray Disc has a capacity of 25 GB. Its main uses are high-definition video and data storage. The disc has the same physical dimensions as standard DVDs and CDs. Because of the wavelength 405 nm( nanometres), substantially more data can be stored on a Blu-ray Disc than on the DVD format, which uses a red (650 nm) laser. Moser Baer has been the first to commerically launch this product.
