This is mainly used for market segmentation for price discrimination, but also allows movie studios to control the various aspects of delivery (including the content and release date) depending on the region.

The Blu-ray disc is a patented digital disk format marketed by the Japanese company Sony. It stores and renders video recordings in High Definition. Its name comes from the type of laser that operates close to the spectral color blue. Blu-ray is simply the technology used to read and write data

Blu-ray uses a high numerical aperture (0.85) blue-violet laser (wavelength: 405 nm). Compared with the infrared laser (wavelength: 780 nm) of 0.45 numerical aperture used for the CD and the red laser (wavelength: 650/635 nm) of 0.6 numerical aperture used for DVD.

Blu-ray can store more information on the same surface with a thinner radius (laser spot diameter: 290 nm) inducing smaller and shorter grooves etching (range: 320 nm) and shorter cells (minimum length: 149 nm – 135 nm for the 27 GB model now abandoned).

The first consumer devices incorporating this technology appeared in late 2006, and these include PlayStation 3 (November in Japan and the United States), launched on 23 March 2007 in France.
