Unlike current DVDs, which use a red laser to read and write data, Blu-ray uses a blue laser (which is where the format gets its name). A blue laser has a shorter wavelength(405 nanometers) than a red laser (650 nanometers).
The smaller beam focuses more precisely, enabling it to read information recorded in pits that are only 0.15 microns (µm) (1 micron = 10-6 meters) long -- this is more than twice as small as the pits on a DVD.
Plus, Blu-ray has reduced the track pitch from 0.74 microns to 0.32 microns. The smaller pits, smaller beam and shorter track pitch together enable a single-layer Blu-ray disc to hold more than 25 GB of information -- about five times the amount of information that can be stored on a DVD.

∙ 12y agoBlu-ray Players can play DVD videos and music CDs unless the DVDs and CD have a code that prohibits them being played. There is a code for the Americas, Europe, Asia, and Africa. Blu-ray players can play all code, or in the USA, code 1, DVDs and CDs. Unless it's coded for another region of the world, your Blu-ray player should be able to play a music CD.
