The volume of information that may be stored in discs depends upon how big and precise the laser light is. Blue laser carries a shorter wavelength in contrast to red laser these types of this, blue laser is a bit more precise which enable it to write information in smaller sized spaces. This is why far more information might be stored in a Blu-Ray disc.

A tremendous storage capacity isn't the only advantage of a Blu-Ray technology. Blu-Ray Discs could also transfer information at a higher rate.
