SEOUL, Korea (AVING) — Blu-ray or Blu-ray Discs (abbreviated as BD) use shorter wavelength blue lasers (405nm) to read and write data, but the traditional DVD uses red lasers (wavelength 650nm). Normally, the shorter wavelength of the laser, the more information can be recorded or read on a unit of area.

So far, Blu-ray is the most advanced high-capacity disc format. Because of the tremendous progress of BD laser technology, you can store 25GB document files on a single disc.

The huge capacity of Blu-ray products creates possibilities and convenience for HD movies.
