ABSTRACT:
A recording and/or reproducing apparatus for a magnetic record carrier such as a tape or disk. The apparatus includes a magnetic recording/reproducing head, a guide for positioning the face of the head relative to a recording surface of the record carrier, and an actuator for moving the head relative to the guide in a direction normal to the recording surface. The actuator is driven by a control unit which receives a control signal from a detector upon detection thereby of frictional contact between the face of the magnetic head and the recording surface. That causes the control unit to cause the actuator to move the head so as to increase the distance between the face thereof and the recording surface.
