摘要
The gain (54) of a playback amplifier (52) is dynamically adjusted in response to a played back periodic test signal based on the number of flux transitions (56) detected during playback of a given length of tape, and an edge of tape reference position (40, 42) thereafter established by comparing the number of flux transitions detected during the playback of a periodic test signal recorded along the edge of a given length of tape when the recording/playback unit is successively stepped toward the edge of the tape.
