<p>A head positioning control apparatus and method which compensates for positional deviation of a magnetic head with respect to the positioning of the head on a particular track of a disc recording medium via a tracking control. Additionally, during a seek mode of the apparatus, a head that was positioned as a result of the tracking control is moved to a neighboring track of the disc recording medium. The seek mode uses the information obtained during the tracking mode to correct any disturbance frequencies occurring in synchronism with the rotational frequency of the disc recording medium, even if the head travels over a large distance.</p> |
