SEMINAR ON BLUERAY-DISC : Tokyo Japan, February 19, 2002: Nine of today's leading announced they have jointly established the basic specifications for the next generation of high capacity optical disc video recording format called Blu-ray Disc. "Blu-ray Disc enables recording, rewriting and playback of up to 27 gigabytes (GB) of data layer 12 cm single-sided CD / DVD size using a 405nm laser blue-violet. Using a laser shorter wavelength blue-violet, Blu-ray Disc successfully minimizes its beam spot size by making a numerical aperture (NA) field lens converges the laser 0.85. In addition to using the disk layer structure with a 0.1 mm optical transmission protection, the Blu-ray Disc deviation decreases due to disk tilt. This also allows for disc better readout and a recording density has increased. not follow Blu-ray Disc is reduced to 0.32um, almost half that of a standard DVD, up to 27 GB of high density recording on a single sided disc.
Since the Blu-ray Disc utilizes global standard for MPEG-2 Transport Stream compression technology highly compatible digital broadcasting video recording, a wide range of content can be recorded. You may Blu-ray Disc to record digital high definition television, while quality and other data at the same time as the video data if they are received together. In addition, by adopting a unique identifier on a Blu-ray Disc realizes high quality copyright protection functions.
Blu-ray Disc is a technology platform that can store audio and video while maintaining the high quality and also access to content stored on a user-friendly way. This is important in the coming era of broadband content distribution becomes increasingly diversified. The nine companies involved in message, to develop products that take full advantage
Blu-ray Disc high-capacity and high speed data transfer speed. They are also increase the attractiveness of the new format through developing a higher capacity, more than 30 GB in a single-sided disc single layer and more 50 GB on a disk in a single-sided, double layer. Adoption of the Blu-ray in a range of applications including PC data storage and high definition video
software under consideration.
