Head control method and recording apparatus

摘要

A head control method controlling movement of a head on a recording disk. The disk has servo information recorded thereon at radially equal spacing, and is partitioned into one or more zones each associated with a coefficient for converting from actual track numbers based on the servo information, to apparent track numbers, allowing the apparent tracks to be given a variable spacing on the disk. At least in the case of a single zone, the coefficient is variable.
