ABSTRACT:
A process allows a disk drive system to optimize head position in order to minimize the effects of track variations due to disk misclamping and imperfections. The process utilizes a transducer head having a width less than a track width. The small size of the transducer head allows it to be positioned within a stationary band which remains within the boundaries of the track for the complete revolution of the disk. Once the head is positioned within this band for one track of the disk, this track can be used as a reference for positioning the head within the bands of the other tracks.
