Laserdisc
The LaserDisc (LD) is a home video format and the first commercial optical disc storage medium, initially licensed, sold and marketed as MCA DiscoVision (also known simply as "DiscoVision") in the United States in 1978. Its diameter typically spans . Unlike most optical disc standards, LaserDisc is not fully digital, and instead requires the use of analog video signals. Although the format was capable of offering higher-quality video and audio than its consumer rivals— VHS and Betamax videotape—LaserDisc never managed to gain widespread use in North America, largely due to high costs for the players and the inability to record TV programmes. It eventually did gain some traction in that region and became somewhat popular in the 1990s. It was not a popular format in Europe and Australia. By contrast, the format was much more popular in Japan and in the more affluent regions of Southeast Asia, such as Hong Kong, Singapore and Malaysia, and was the prevalent rental video me ...

Optical Disc
In computing and optical disc recording technologies, an optical disc (OD) is a flat, usually circular disc that encodes binary data ( bits) in the form of pits and lands on a special material, often aluminum, on one of its flat surfaces. Its main uses are physical offline data distribution and long-term archival. Changes from pit to land or from land to pit correspond to a binary value of 1; while no change, regardless of whether in a land or a pit area, corresponds to a binary value of 0. Non-circular optical discs exist for fashion purposes; see shaped compact disc. Design and technology The encoding material sits atop a thicker substrate (usually polycarbonate) that makes up the bulk of the disc and forms a dust defocusing layer. The encoding pattern follows a continuous, spiral path covering the entire disc surface and extending from the innermost track to the outermost track. The data are stored on the disc with a laser or stamping machine, and can be acces ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

David Paul Gregg
David Paul Gregg (March 11, 1923 – November 8, 2001) was an American engineer. He was the inventor of the optical disc (disk). Gregg was inspired to create the optical disc in 1958 while working at California electronics company, Westrex, a part of Western Electric. His patent for a "Videodisk" was filed in March 1962 (USPO 3350503) while working to advance electron beam recording and reproducing. Gregg went to work at 3M's Mincom division with experienced television videotape engineers Wayne Johnson and Dean De Moss. The three men subsequently filed patents to cover a disc-recording system, a way to duplicate discs, and reproducing TV signals from photographic discs. When Mincom contracted Stanford's SRI to further the research, Gregg left and formed his own company, Gauss Electrophysics. In 1968 the Gregg and Gauss patents were purchased by MCA (Music Corporation of America), which helped develop the technology further. His designs and patents paved the way for the Laser ...

Philips
Koninklijke Philips N.V. (), commonly shortened to Philips, is a Dutch multinational conglomerate corporation that was founded in Eindhoven in 1891. Since 1997, it has been mostly headquartered in Amsterdam, though the Benelux headquarters is still in Eindhoven. Philips was formerly one of the largest electronics companies in the world, but is currently focused on the area of health technology, having divested its other divisions.

Betamax
Betamax (also known as Beta, as in its logo) is a consumer-level analog recording and cassette format of magnetic tape for video, commonly known as a video cassette recorder. It was developed by Sony and was released in Japan on May 10, 1975, followed by the US in November of the same year. Betamax is widely considered to be obsolete, having lost the videotape format war which saw its closest rival, VHS, dominate most markets. Despite this, Betamax recorders continued to be manufactured and sold until August 2002, when Sony announced that they were discontinuing production of all remaining Betamax models. Sony continued to sell Betamax cassettes until March 2016. Original version Launch and early models The first Betamax device introduced in the United States was the LV-1901 console, which included a color monitor, and appeared in stores in early November 1975. The cassettes contain videotape in a design similar to that of the earlier, professional , U-matic format. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Videodisc
Videodisc (or video disc) is a general term for a laser- or stylus-readable random-access disc that contains both audio and analog video signals recorded in an analog form. Typically, it is a reference to any such media that predates the mainstream popularity of the DVD format. History Georges Demeny on 3 March 1892 patented a 'phonoscope', designed in 1891, that can project chronophotographic pictures on a glass disc. Eadweard Muybridge used his zoopraxiscope to project chronophotographic pictures on a glass disc in 1893. E & H T Anthony, a camera maker based in New York, marketed in 1898 a combination motion picture camera and projector called "The Spiral" that could capture 200 images arranged in a spiral on an 8-inch diameter glass plate. When played back at 16 frames per second, it would give a running time of 13 seconds. Theodore Brown patented in 1907 (UK patent GB190714493) a photographic disk system of recording approximately 1,200 images in a spiral of pictures on a ...
