<p>In a tracking control method for a tape-shaped recording medium such as a magnetic tape having information signals and signals for carrying out tracking control of the tape-shaped recording medium being recorded on a plurality of slanted tracks, a value of measured time duration, which is from a time when a head passes a reference phase position of the head within one rotation of a rotational drum provided with at least one head to a time when the head starts to reproduce a signal for controlling the transporting speed recorded on the tape-shaped recording medium, and a reference value are compared, whether or not the difference between the value of measured time duration, which is from the time when the head passes the reference phase position of the head within one rotation of the rotational drum to the time when the head starts to reproduce a signal for carrying out tracking control recorded on the tape-shaped recording medium, and the reference value falls within a prescribed range is determined and the relative speed of the transporting speed of the tape-shaped recording medium and the peripheral speed of the rotational drum is controlled on the basis of the comparison results when the determination result falls within the prescribed range. <IMAGE></p> |
