Abstract

PURPOSE:To evade the permanent loop to be caused at the time of servo- correcting and to enable to return to a recording/reproducing mode by performing the servo correction according to one of servo information, when the judgment of the servo correction differ. CONSTITUTION:It is assumed that servo control is performed to the same servo track according to the servo information written in two servo areas at least, and respective on-track judgment based on the result of the servo correction, differ till the upper limit of the predetermined number of times of servo correction. In such a case, in neglecting the servo information about the magnetic head 1 of the one side servo area, the servo correction is performed according to only the servo information of the magnetic head 2 of the other side servo area.
