多トラツク長時間録音機。 In an apparatus for recording and playing back multiple tracks, there are a means for recording a pilot signal of a fixed period on a specific track, a means for detecting changes in the playback output obtained from that track, and a means for detecting changes in the playback output obtained from adjacent tracks. a filter means for extracting a pilot signal from the head, a means for detecting the current position of the head from two playback outputs, a head or tape guide mounted so as to be movable in the vertical direction, and an actuator for moving the head or tape guide. It has a means for temporarily storing changes in playback output when the head or tape guide is moved, and generates a control output by determining the current state, and outputs a control output to the actuator. A multi-track long-time recording device characterized in that the head is automatically placed in the center position of the tracks by adding the following features.
