  • Sony NT-2 is an improved version of the Sony Digital Micro Recorder NT-1.

    Both models are designated by “Scoopman” and use the same type of cassette tape, developed by Sony. The NT cassette tape is the world smallest tape cassette.

    Both recorders use the Sony NT Non Tracking system. This system uses a miniature rotary head drum doing helical scanning of the tape in a way similar to that of used in video tape recorders. The rotary heads rotate at double speed and the reading of tracks provides one complete track and two track segments. The track synchronization is obtained by a special chip that detects the signals of the valid track, rejecting the other segments, avoiding the complication of the mechanical synchronization of tracks.
