Abstract:
A tracking control apparatus for a tape-shaped recording medium on which plural inclined tracks are formed, each of the tracks is composed of plural recording areas, and timing signals are respectively recorded in the recording areas, the apparatus comprising:a rotary drum provided with at least one head;a control section for controlling a relative velocity between a traveling velocity of the tape-shaped recording medium and a rotational velocity of the rotary drum; anda control signal generating section for measuring times from a time point serving as a reference phase position within one period of the rotary drum to time points when timing signals of the respective recording areas of the tape-shaped recording medium are detected by the head to generate error information for controlling the relative velocity on the basis of a comparison between the measured times and a value serving as a reference and for generating a control signal delivered to the control section on the basis of error information generated with respect to the track of the tape-shaped recording medium being scanned by the head and error information generated with respect to the track preceding by one relative to the track scanned by the head.
