Blu ray is an optical drive used to read blue discs.Blu ray is the most advanced high - capacity compact disk format, and the tremendous advances in BD laser technology allow you to store 25GB document files on a single disk. This is 5 times the existing (Dan Die) DVDs. At speed, blue light allows 1 to 2 times, or 4.5 to 9 megabytes per second.In addition to all Blu ray compatible Blu ray disc player, can support CD, DVD disk, users can DVD up to 1080P times the line will continue to use its input, so as to facilitate the use of DVD habits.

Hello, Blu ray (Blu ray), or BD 405nm (Blu ray Disc), short wavelength (blue) laser to read and write data, and thus get its name. The smaller the wavelength of light, the more information can be recorded on the unit area, and more information can be read naturally. The wavelength of blue laser is shorter than that of red light. Traditional DVD requires light hair with a red laser (650nm) to read or write data. Blu ray technology has greatly improved the storage capacity of the optical disk, and for the optical storage products, Blu ray provides a chance for leaps and bounds. So far, Blu ray is the most advanced high-capacity optical disk format, and the great advances in BD laser technology allow you to store 25GB document files on a single disk.
