ABSTRACT:
A magnetic-record reproduction system is provided for selectively reproducing magnetic information signals recorded on a magnetic tape as a plurality of programs, each program being separated from other programs by cue signals. The system includes a head for reproducing the recorded magnetic information, a movable tension arm for maintaining the head in tensioned contact with the magnetic tape, and a cue signal detector mounted to the tension arm to enable selection of recorded programs thereby. A cavity is formed in the tension arm for receiving a magnetoresistive element to form the detector, and a non-magnetic metallic film is mounted on the surface of the tension arm to protect the arm from abrasion as it contacts the magnetic tape.
