Blue laser carries a shorter wavelength compared to red laser and because of this, blue laser is much more precise and may write information in smaller sized spaces. Because of this , why a lot more information can be kept in a Blu-Ray disc.

A tremendous storage capacity is not the only advantage of a Blu-Ray technology. Blu-Ray Discs could also transfer information in a higher rate.
