SuperBeta Hi Fi
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.

Magnetic Cassette Tape
Magnetic tape cartridge and magnetic tape cassette both refer to a small plastic unit containing a length of magnetic tape on at least one reel. The unit may contain a second "take-up" reel or interoperate with such a reel in an associated tape drive. At least 142 distinct types have been known to exist. The phrase ''cassette tape'' is ambiguous in that there is no common dictionary definition so depending upon usage it has many different meanings, as for example any one the one of 106 different types of audio cassettes, video cassettes or data cassettes listed aThe Museum of Obsolete Media The phrase ''cartridge tape'' is also ambiguous with 36 different types of audio, video or data cartridges listed at The Museum of Obsolete Media. From time to time the terms tape cartridge and tape cassette are used to describe the same product. In current production are the Cassette tape, the Linear Tape-Open#Cartridges, LTO tape cartridge and the IBM 3592#Cartridges, IBM 3592 tape cartri ...

U-matic
U-matic is an analogue recording videocassette format first shown by Sony in prototype in October 1969, and introduced to the market in September 1971. It was among the first video formats to contain the videotape inside a cassette, as opposed to the various reel-to-reel or open-reel formats of the time. The videotape is wide, so the format is often known as "three-quarter-inch" or simply "three-quarter", compared to open reel videotape formats in use, such as type C videotape and quadruplex videotape. Unlike most other cassette-based tape formats, the supply and take-up reels in the cassette turn in opposite directions during playback, fast-forward, and rewind: one reel would run clockwise while the other would run counter-clockwise. A locking mechanism integral to each cassette case secures the tape hubs during transportation to keep the tape wound tightly on the hubs. Once the cassette is taken off the case, the hubs are free to spin. A spring-loaded tape cover door pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Murphy Radio
Murphy Radio was a British manufacturer of radios and televisions based in Welwyn Garden City, England. Murphy Radio was founded in 1929 by Frank Murphy and E.J.

Moviola
A Moviola () is a device that allows a film editor to view a film while editing. It was the first machine for motion picture editing when it was invented by Iwan Serrurier in 1924. History Iwan Serrurier's original 1917 concept for the Moviola was as a home movie projector to be sold to the general public. The name was derived from the name "Victrola" since Serrurier thought his invention would do for home movie viewing what the Victrola did for home music listening. However, since the machine cost $600 in 1920 (), very few sold. An editor at Douglas Fairbanks Studios suggested that Iwan should adapt the device for use by film editors. Serrurier did this and the Moviola as an editing device was born in 1924, with the first Moviola being sold to Douglas Fairbanks himself. Many studios quickly adopted the Moviola including Universal Studios, Warner Bros., Charles Chaplin Studios, Buster Keaton Productions, Mary Pickford, Mack Sennett, and Metro-Goldwyn-Mayer.
