Sony's AccuCORE technology, which was first integrated into recordable DVD media over a year ago, has been re-engineered for Blu-ray Discs to deliver enhanced reliability and durability. Its major benefits include the following:
- Scratch Guard--hard coating that resists scratches, dust and static
- Archival Reliability--special material design that prevents data and image corruption and deterioration to ensure quality playback
- Stable Writing--a uniform and precise cover layer that reduces fluctuation as the disc spins
- Temperature Durability--a high-precision disc structure helps prevent warping during severe changes in temperature and humidity.
Sony's Blu-ray media also supports a 2X recording speed, which provides a data transfer rate of up to 72Mbps, making it suitable for high-definition video recording and data storage applications. In addition to media, Sony will soon offer a wide range of Blu-ray Disc devices, including a Blu-ray Disc player, VAIO desktop and notebook computers, and an internal Blu-ray Disc drive. With devices such as these, you could conceivably edit high-definition video shot on a Sony HDV camcorder on a Blu-ray-enabled computer, then burn it onto Blu-ray Disc media, and finally play it back on a Blu-ray Disc player.
Sony is not new to the blue laser-based format. The company released its first Blu-ray Disc recorder and media in Japan in 2003. The following year, Sony helped found the Blu-ray Disc Association, which now has over 160 members and contributors from various industries, to promote the new format.
Sony has been producing Blu-ray Disc recording media in a cartridge format for several years, but has recently begun producing bare discs for the launch in the U.S. and elsewhere. The BD-R (write-once) 25GB and BD-RE (rewritable) 25GB recording media have suggested retail prices of $20 and $25, respectively. The soon to come BD-R 50GB and BD-RE 50GB recording media will have suggested retail prices of $48 and $60, respectively.
