ABSTRACT:
A reproducing apparatus wherein control of rotation of a rotary head, control of tape transportation and a control of the tracking of the head adjusting actuator are processed in a time-share fashion by a data processing device. The control is carried out by using a timer circuit, which has a period of one or several integer times the period of rotation of the rotary head. Computing processes for the above controls are selectively carried out on a time-shared basis. By using a DC component of the tracking error signal, a track transporting system capable of noiseless playback, and which has a wide range of tracking control.
