A top-loading, Magnavox-brand LaserDisc player with the lid open A front-loading, Pioneer CLD-1030 CD/CDV/LD player The earliest players employed gas helium–neon laser tubes to read discs and had a red-orange light with a wavelength of 632.8 nm , while later solid-state players used infrared semiconductor laser diodes with a wavelength of 780 nm.
A LaserDisc player is a device designed to play video ( analog) and audio ( analog or digital) stored on LaserDisc. LaserDisc was the first optical disc format marketed to consumers; it was introduced by MCA DiscoVision in 1978. From 1978 until 1984, all LaserDisc player models read discs by using a helium–neon laser.
The LaserActive (レーザーアクティブ, RēzāAkutibu) is a converged device and fourth-generation home video game console capable of playing LaserDiscs, Compact Discs, console games, and LD-G karaoke discs. It was released by Pioneer Corporation in 1993. In addition to LaserActive games, separately sold add-on modules (called "PACs" by ...
The CLD-1010 was also the first LaserDisc player capable of playing the then-new CD Video format of discs. Although its high price and the general worldwide disinterest in LaserDisc kept the player from becoming a major success, it is today often lauded by those who continue to enjoy the now defunct LD format.
This disc format, called LD-ROM, stored the software for a home entertainment system that Pioneer introduced in 1993. This system, the Pioneer LaserActive, was a cross-platform video game console, Laserdisc player, and CD player. LD-ROMs owe their greater capacity to a design for constant linear velocity (CLV) playback.
This is a partial list of multiple Olympic gold medalists, listing people who have won four or more Olympic gold medals. Medals won in the 1906 Intercalated Games are not included.
Unlike before, the LD was the result of a proper joint venture development programme. That is, Nissan provided the bodywork and Holden supplied powertrains for fitment in both applications. Launched concurrently in July 1987, both the LD Astra and N13 Pulsar were offered in four-door sedan and five-door hatchback body styles.
Linear dichroism ( LD) or diattenuation is the difference between absorption of light polarized parallel and polarized perpendicular to an orientation axis. [1] It is the property of a material whose transmittance depends on the orientation of linearly polarized light incident upon it. As a technique, it is primarily used to study the ...
