The MUSE players were also capable of playing standard NTSC format discs and are superior in performance to non-MUSE players even with these NTSC discs. The MUSE-capable players had several noteworthy advantages over standard LaserDisc players, including a red laser with a much narrower wavelength than the lasers found in standard players.
On May 20, 1994, Panasonic released the first MUSE LaserDisc player. [11] There were a number of MUSE LaserDisc players available in Japan: Pioneer HLD-XØ, HLD-X9, HLD-1000, HLD-V500, HLD-V700; Sony HIL-1000, HIL-C1 and HIL-C2EX; the last two of which have OEM versions made by Panasonic, LX-HD10 and LX-HD20. Players also supported standard ...
The following are examples of optical storage media excluded from this article: Holographic data storage - either still in development, or available but generally only encountered in niche usage as of 2007. Laserdisc - not used for recordable data storage in the computing world, although recordable formats did exist briefly.
The first laser disc, demonstrated in 1972, was the Laservision 12-inch video disc. The video signal was stored as an analog format like a video cassette. The first digitally recorded optical disc was a 5-inch audio compact disc (CD) in a read-only format created by Sony and Philips in 1975. [53]
[2] [3] It was a new variety of laserdisc and variation on the CD Video (CD-V) format, except that VSD disc carried only a video track (of up to 5 minutes' duration), and its associated audio, with no CD-compatible partition. The disc is the same size as a standard CD and holds five minutes of video with digital sound.
It was the introduction of semiconductor lasers that provided the technology needed to make optical storage more practical in both storage density and cost terms. Prices fell to the point that they could be used in consumer products, leading to the 1978 introduction of the analog LaserDisc format.
The LV-ROM is a specialized variation of the CAV Laserdisc. LV-ROM is an initialism for "LaserVision Read-Only Memory". Like Laserdisc, LV-ROM discs store analog audio and video by encoding it in pulse-width modulation. However, LV-ROM also stores computer files via the Advanced Disc Filing System, which is the file system used by Acorn Computers.
Comparison of several forms of disk storage showing tracks; green denotes start and red denotes end. Some CD-R(W) and DVD-R(W)/DVD+R(W) recorders operate in ZCLV, CAA or CAV modes. MiniDiscs use rewritable magneto-optical storage to store data. Unlike DCC or the analog Compact Cassette, MiniDisc is a random-access medium, making seek time very ...
