About Verbatim Verbatim is a subsidiary of Mitsubishi Kagaku Media, based in Japan. Mitsubishi Kagaku Media s wide-range of operations makes it one of the leading chemical companies in the world. Mitsubishi Kagaku Media s pioneering strength is visible in its products, for which the research and development is carried out in the Mizushima Research Centre. The company also has strong relationships with the major hardware manufacturers in the market. These two strengths benefit Verbatim by ensuring not only the latest technologies and products fi rst to market, but also that optical discs bearing our brand are the standard that many hardware companies test their recorders on, making our discs superbly compatible. Mizushima Research Centre High Definition Television provides an unsurpassed picture quality and a remarkable high-end surround sound. With the superb resolution, dynamic contrast, vivid colours and remarkably clear sound effects, high defi nition brings an additional dimension to your visual entertainment. With the expected growth of HDTV, there is a consequent growth in the recording of the HD television programming. Recording 2 hours of standard definition television in standard DVD quality requires a full 4.7GB DVD disc. High Definition content – with its increased resolution and digital sound tracks requires an ever greater amount of storage capacity. Verbatim’s Blu-ray discs range from 25GB to a massive 50GB which is more than enough HD storage space. 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.
