Proprietary name for an analog videocassette format developed by Sony in 1969, using 3/4 inch tape with a running speed of 3.75 inches per second. The format was popular in semi-professional industrial, educational and broadcast contexts from the 1970s until the advent of digital video technology.
U-matic was also used for the storage of digital audio data. Most digital audio recordings from the 1980s were recorded on U-matic tape via a Sony PCM-1600, -1610, or -1630 PCM adaptor.
There are three types of U-matic format: Lo-band (1969-1990s), Hi-band (1980s-1990s), and U-matic SP (1986-late 1990s).
