[ENG] U-matic S SP | U-matic S SP (1986 – late 1990s) | U-matic S (for ‘Small’) was a smaller size of U-matic video tape cassette, first introduced in 1974 for use in compact recording decks by television news crews. U-matic S tapes generally had recording times of no more than 20 minutes, though 30-minute S tapes were also available using thinner tape. | U-matic SP (Superior Performance) was a variant of the U-matic video cassette format, and was introduced by Sony in 1986. This was also made available in the S size format. SP used chrome tape and offered an improvement in performance over previous generations of U-matic (low-band and high-band) with a a horizontal resolution of 330 lines, a better signal to noise ratio, and Dolby C noise reduction. | Like previous generations of U-matic, the SP variant was analogue and used ¾-inch tape. SP tapes of either size can be played on a standard U-matic deck, albeit with a loss in quality. | U-matic tape was replaced in broadcast applications by Sony’s own Betacam family of video cassette formats in the 1980s, and for other applications in the 1990s. | Dimensions: 18.5 cm × 12 cm × 3 cm | SOURCE : MUSEUM OF OBSOLETE MEDIA.
