ABSTRACT:
A magnetic tape recording and playback apparatus includes a tape driving system for driving a tape, a recording/playing system for recording/playing/erasing and a linking device for mechanically linking the operations of the tape driving system with the recording/playing system. The tape driving system includes a motor, a gear train coupled to the motor and a reel shaft for rotating reels of the cassette. The gear train includes an planetary gear which swings. The planetary gear selectively rotates the reel shaft in correspondence with respective operation modes of the magnetic recording and playback apparatus. The linking device includes a cam coupled to the planetary gear and a head base mounting a recording/playing head. The cam transmits the driving power from the motor to the head base through the planetary gear. The head base moves corresponding to the shape of the cam and in association with the operation of the planetary gear. Operation such as recording and playing is carried out on the tape by the movement of the head base.
