A video tape recorder (VTR) is designed to record and play back video and audio material from magnetic tape.
In 1956, Ampex Corporation introduced the first practical videotape recorder for television stations to produce and time-shift broadcasts, replacing impractical “kinescope” movie film previously used to record TV.
Worldwide, the Ampex “VTR” analog-video standard was the predominant recorder used for broadcasting and video production for twenty years.
