Patent ID: 7333288

Claim:
A method of initializing a disk surface included in a disk in an assembled hard disk drive, comprising the steps: determining a voice coil motor control contribution and a voice coil motor plant contribution to a Repeatable Run-Out (RRO) corrector function of a track on said disk surface; determining a micro-actuator control contribution to said RRO corrector function of said track on said disk surface; and writing the parameters of said RRO corrector function for said track to said disk surface to create a written-in RRO corrector function parameter list on said disk surface included in a hard disk drive; wherein said parameters of said RRO corrector function, include: at least one parameter for said voice coil motor control contribution; at least one parameter for said voice coil motor plant contribution; and at least one parameter for said micro-actuator control contribution; wherein said hard disk drive includes a voice coil motor and a micro-actuator contributing to at least the lateral position of a read-write head to said track on said disk surface.
