The 'blu' in Blu-ray comes from the blue laser it uses to write and read data, which utilizes a shorter 405 nanometer wavelength than the 650 nanometer used by traditional red laser for CD and DVD. The shorter wavelength means increased precision in the focus of the laser spot, allowing more data to be packed more tightly and stored on a disc the same physical size as the CD and DVD.

The BD mastering process input format is CMF 0.9 saved on a USB or Firewire external hard drive. The CMF master is loaded and the data analysed. Then the client's AACS Content Provider Licensee ID is encoded together with the replicator's AACS key and sent to AACS for AACS Content Certificate processing. After the AACS reverts with the Private Host Key cryptographic certificate, the stamper can be made at which stage the BD-ROM Mark is encoded. The stamper is then ready for use in replication. The entire process takes approximately two weeks.
