Blu-ray, current big news item in home entertainment, is here to stay. This disc-based video playback and recording format that was developed expressly for use with high-definition TV boasts supreme quality as well as high data capacity for movies, computer data, and photographic images.
Those in the know-and those who are sticklers for crisp and flawless video quality-have been waiting for Blu-ray's arrival with wide-eyed anticipation. Its name, which sounds like something out of a superhero comic, is derived from the violet-blue color of the internal laser that reads the disc's data.
Blu-ray was developed through a collaboration of technological giants, including Dell, Sony, Apple, and Hewlett-Packard. These companies united as the Blu-ray Optical Disc Association (BDA) to pool their resources in perfecting this long-awaited advance in home video entertainment (movies as well as games) and personal computer data storage. It outdoes previous technology with its superior clarity and definition in both playback and recording, its vivid colors, and crisp audio.
Another major advantage of the Blu ray disc (BD) is its much higher storage capabilities: a Blu-ray disc may hold 500% of the data a DVD can hold. This is possible since its aperture is larger than what the DVD uses, letting the Blu-ray disc run at a lower rotation speed and therefore store more data. Think of the old VHS technology with its multiple recording speeds; the EP (extended play) mode, also known as SLP (super-long play), moved more slowly and could record three times the amount of programming as the fast-moving SP (standard play) mode. In that case, though, there was an obvious difference in quality-something that is absolutely not the case with the spectacular Blu-ray.
So, although the discs are the same physical size as the DVD, the video publisher can fit a lot more "stuff" on them, meaning you can look forward to more outtakes, interview features, and other bonus material on the movies you rent. These super high-quality discs are also made tough, resisting scratches and breakage more so than DVDs and affording significantly more hours of clear viewing.
Blu-ray players made are in stores across North America now, with movie titles already released by Fox, MGM, Disney, Paramount and other leading media producers. They're already quite popular, but you can look for sales to really take off as the holidays approach. As part of the transition process from DVD to BD, hybrid-type players that play both formats should soon be readily available.
