<p>A tape recorder records and/or reproduces information signals by bringing a magnetic tape into sliding contact with a magnetic head on a rotary head mechanism. This tape recorder comprises a rotary head mechanism including a rotating drum fitted with a magnetic head for bringing the head into sliding contact with running tape, and a fixed drum coaxial with the rotating drum for rotatably supporting the latter; a pair of supporting members rotatably supported on the rotary head mechanism; a pair of capstans rotatably mounted on ends of the supporting members; and a pair of pinch rollers opposed to the corresponding capstans. The pair of supporting members are rotated in accordance with the direction in which the magnetic tape travels. Either one of the capstans is selectively moved toward either one of the pair of the pinch rollers in order to pinch the magnetic tape between the capstan and pinch roller. Further, the capstan and pinch roller cooperate to drive the magnetic tape, thus implementing the switch over in the traveling direction of the magnetic tape.</p> |
