解かれることを特徴とする磁気記録再生装置。[Claims for Utility Model Registration] The movement of the head is linked to the rotation of a spindle via a transmission mechanism, and the movement of the head records and reproduces information on a magnetic disk medium rotated by the spindle. In a magnetic recording/reproducing device in which a head arm to which a head is attached is energized with a restoring force so that the head arm always returns to its home position, a capstan having a cutout portion in which a part of a cylinder is cut out is used as described above. The free end of the drive belt is rotated appropriately by a transmission mechanism, and a freely rotatable pinch roller is provided near the capstan, and the free end of the drive belt is wound around an arm pulley whose base end is fixed to the chassis and whose middle part is pivotally supported by the head arm. is always located between the capstan and the pinch roller,
It is possible to restrain and push the drive belt between the arc-shaped portion of the capstan and the outer periphery of the pinch roller, and when the notch of the capstan faces the pinch roller, the restraint of the drive belt is released. A magnetic recording/reproducing device characterized by:
