| 摘要 |
This specification describes a signal recording and/or playback apparatus for recording signals on a broad record band in a plurality of parallel tracks or track sections and/or for playing back signals so recorded. The apparatus described includes a transducer head which is driven across the record band in a series of steps, means being provided which ensure that each step corresponds to the spacing between two tracks or track sections. The apparatus described also includes a position indicator for indicating the position of the transducer head along the length of the band. This counter is reset to zero by means adapted to be actuated by trigger means provided on the band at a position corresponding to the ends of the tracks or track sections in which said signals are recorded or to be recorded. In a modification, two transducer heads are provided which are rendered operative during alternate periods, each of said heads being shifted to another track while it is inoperative.
