Blu-Ray disc

A New Era Of Reviews

Blu-Ray has the ability to hold 25 Gigabytes for watch layer. This is accomplished by utilizing a blue laser with strength of 405 mm. The numerical aperture is raised to .85 and lowered the cover layer to .1 mm. As the name states, it is a joined effort of the Blue for the ray color and the ray for the optical ray that is used.

This blue laser does not have a length for the waves as long as the red laser does. This will focus in on a particular spot without mistakes. The data can be written tighter on the disc giving you more room to add. The change of the aperture is also a part of what makes it hold more even though it is a regular size disc.

A disc with only one layer can hold form 23.3 to 27 Gigabytes respectively. A double layer disc can hold from 46.6 to 54.3 gigabytes. This disc can hold up to 200 Gigabytes, which is a feat that is just amazing.
