What is Blu-ray?
Blu-ray discs (BD) get their name from a combination of the words blue and optical ray. The format was developed
by the Blu-ray Discs Association (BDA), which is made up of a group of leading consumer electronics, major fi lm
studios and PC companies, including our parent company, Mitsubishi Kagaku Media. Verbatim, as a subsidiary of
MKM, has therefore, fi rst hand access to the latest in Blu-ray technology.
Our Research and Development team enables us to be at the forefront of Blue Laser Technology and and we are
currently looking into producing 6x speed discs and quad-layer 100GB capacity discs.
The Blu-ray disc’s higher storage capacity is enabled by a blue laser that has a shorter wavelength than the standard
red laser used in CD (780nm) and DVD (650nm) technology. Blu-ray disc utilises a blue laser with a wavelength of only
405nm combined with a strong lens system with a numerical aperture of 0.85. This results in a ultra-small laser spot
which allows writing smaller data pits which increases the amount of data on the disc. Due to the small data entry spot
on the disc surface hard coating is needed on Blu-ray discs.
