What is Blue Ray disc?

Answer 1

New DVD technology which requires a blue colored laser instead of the normal red one to read the data. This is because the blue laser has a much smaller wavelength, thus allowing individual tracks in DVD to be situated much closed together which allows twice the data amount to be stored on it.

Answer 2

New technology used on DVDs. The current standard uses Red lasers to read the discs. The new "blue ray" uses a blue laser to read discs. The blue ray has a shorter wavelenth so more information can be stored on a single disc. Blue ray readers can read DVDs out now, but blue ray discs can't be read by the current DVD players out there because the laser can't read that small.
