ABSTRACT:
A tracking control device and a magnetic recording and reproducing apparatus including the tracking control device, the tracking control device comprising means for detecting track data recorded on a recording track tracking determining means for determining whether a magnetic head scans a normal recording track on the basis of the output from the track data detecting means and outputting data corresponding to a deviation of the recording track which the magnetic head scans from the normal recording track; means for calculating a deviation of an electrical-to-mechanical converter device on which the magnetic head is mounted from the output data of the tracking determining means such that the magnetic head scans a normal scanning position; and means for driving the electrical-to-mechanical converter device in accordance with the calculated output from the calculating means.
