。 A control signal that rotates the magnetic tape at high speed until a tape position is found where time playback data that matches the specified playback time of the magnetic tape is identified, by arranging a data recording and playback unit consisting of a magnetic head, a playback circuit, an encoder, and a decoder. This high-speed magnetic tape recording and reproducing device is composed of a controller, a drive circuit, a motor, and a tachometer, and is characterized by driving a tape device using the time characteristics from when the magnetic tape rotates at high speed until it stops as a parameter.
