After Pioneer released the LD-700, gas lasers were no longer used in consumer players, despite their advantages, although Philips continued to use gas lasers in their industrial units until 1985. One year earlier Hitachi introduced an expensive industrial player with a laser diode, but the player, which had poor picture quality due to an inadequate drop-out compensator, was made only in limited quantities. It was also the first LD player to load from the front and not the top. In March 1984, Pioneer introduced the first consumer player with a solid-state laser, the LD-700. From 1978 to 1984, all LaserDisc players, either industrial or consumer, used helium-neon laser tubes. Both the Magnavox Magnavision and the Pioneer LD players used the same model of laser tube. The earliest players employed gas helium–neon laser tubes to read discs and had a red-orange light with a wavelength of 628 nm, while later solid-state players used infrared semiconductor laser diodes with a wavelength of 780 nm. The last models Pioneer produced were the DVL-919 (an LD/ DVD player), CLD-R5 (an LD/ CD player), DVK-900 (an LD/DVD karaoke system), and DVL-K88 (an LD/DVD karaoke player). Pioneer announced the end of LaserDisc player production in January 2009. In 1996, Pioneer distributed their first DVD player in Japan, a combination Laserdisc/DVD player, model DVL-9. In the 1990s, Pioneer and others produced a small number of a high-definition video player models, which employed multiple sub-Nyquist sampling encoding (MUSE) technology. Pioneer became the market leader in LaserDisc technology. This model, the Pioneer LD-700, was also the first LaserDisc player with a front-loading disc bay instead of a top-loading one. In 1984, Pioneer Corporation introduced the first consumer player with a solid-state laser diode. LaserDisc was the first optical disc format marketed to consumers it was introduced by MCA DiscoVision in 1978.įrom 1978 until 1984, all LaserDisc player models read discs by using a helium–neon laser. A top-loading, Magnavox-branded LaserDisc player with the lid open.Ī LaserDisc player is a device designed to play video ( analog) and audio ( analog or digital) stored on LaserDisc.
