Abstract
A hard disk drive optimization method, medium, and apparatus, particularly, a method, medium, and apparatus optimizing the number and gains of RRO compensators for the hard disk drive apparatus. The PRO compensation method can includes measuring the magnitude of a position error signal (PES) at each zone on a disk while gradually increasing the number of RRO compensators applied to a corresponding zone, and determining the number of RRO compensators, with which the PES with a minimum magnitude was measured, as an optimal number of RRO compensators for the corresponding zone, based on the PES measurement results.
