Can a DVD burner also copy blu ray disks?
DVD burners are not compatible with blue-ray disks. Only a Bluray drive is capable of handling Bluray discs.
The term BlueRay is derived from the actual wavelength of the laser that is used in the burning process. This laser emits a Blue color as opposed to the lasers previous which use a laser in a wavelength that emits a red color. The actual Blue ray lasers are much finer ( like comparing a pencil tip to a needle tip) therefor the information written to disc is much more compact and as a result a normal laser can not read information written with a blue ray burner.
