Abstract
In a magnetic reproduction system in which a magnetic tape must be controlled to run so as to keep a specified relative phase to a rotary phase of a rotary head, a tracking control apparatus obtains a characteristic curve showing a characteristic relationship between the relative phase and an envelope level of a reproduced information signal obtained by the rotary head by changing the relative phase, obtains a regression curve with respect to the characteristic curve, and controls the magnetic tape to run so that the relative phase becomes a value corresponding to a maximum value point of the regression curve.
