The standard DVD format is overcome by the blu-ray disc. The standard DVD player uses the red laser which is of 650 nm and the blu-ray DVD player in which the name itself indicates that the laser used is using violet or blue colored laser. The normal standard DVD player stores six times less than that of the blu-ray DVD player.
While considering the vulnerability of the scratches, the blu-ray data layer is closer to the surface of the disc when it is compared to the normal standard DVD. Initially cartridges were used for the protection purpose. Already the blu-ray players are expensive and the use of cartridge increased the one. The hard coating of the pick up surface has been selected to avoid the problem. The scratch resistant and anti static coating was used later to overcome the problem. The scratch guard technology which is the hard coat technology has been used by the blu-ray disc. The storage capacity of the disc can be improved by such technology when compared to the standard one. The blu ray which has shorter wavelength when compared to red is helpful in storing more information on a CD size. This shorter wavelength of the laser beam and the aperture size of the lens help in determining the spot size and the diffraction limit it.
The standard blu-ray records about 36 Mbps. This is more than enough to record high definition broadcast. The standard television programming uses MPEG transport. This is similar in the blu-ray DVD players. This helps in producing the picture in picture effect which is by the availability of the multiple video programs in the same file which can be played back simultaneously.

The knowledge about the blu-ray players is important, because it not only provides good audio quality but also provides extra storage capacity and also provides plenty of rooms for extra content and some special features.

This blu-ray discs are sometimes capable of reading standard DVD's and also CD's, but a few old generation players are not able to read CD's, but they have the capability to read the standard DVD's. The player discs with the provision of the optical disc recorder ensure that they have he capacity to record the favorite programs.
