Abstract
PURPOSE:To reduce time for correction control by reading the result of preliminary measurement of off-track quantity from a storage means, correcting the position of a head based on the value and correcting the position of the head so as to bring the detected off-track within a permissible limit. CONSTITUTION:A command is sent from an off-track preliminary measurement means 30 to an off-track detection means 20 to detect the off-track quantity of the track, the off-track quantity is summed and the result is divided by a track number to obtain a mean off-track quantity for each band with respect to all tracks and stored in the off-track storage means 40. Then a head operation control means 50 reads a mean off-track quantity from the storage means 40 to give a drive signal to a drive circuit 6 thereby positioning the head 3 onto a correct position on a desired track. Succeedingly, the means 50 gives a detection command to the circuit 20 to detect an off-track quantity delta and correct the position so that the value comes within a permissible limit.
