COMPENSATION METHOD FOR POSITION ERROR SIGNAL ACCORDING TO DISTORTED COMPONENTS IN MAGNETIC DISK DRIVER OF TRACKING OPERATION

摘要

1. TECHNICAL FIELD OF THE INVENTION;A magnetic disk drive recording apparatus for magnetic recording / reading of digital information, and more particularly, the head following a track following a head on another disk while the head tracks to read data from a specific track on one magnetic disk. The present invention relates to a method of compensating off-track when switching.;2. The technical problem to be solved by the invention;In general, a hard disk driver has a mechanical component and a circuit component, and among them, the response characteristics of the head switching are degraded due to a system error caused by the mechanical component.;3. Summary of Solution to Invention;In the magnetic disk drive recording apparatus for magnetic recording / reading of digital information, the track following head is switched to the head on another disk while the head tracks in order to read data from a specific track on one magnetic disk. It provides a more stable way to compensate when doing so.;4. Important uses of the invention;Compensation for off-track generation immediately after head switching during track tracking in a magnetic disk drive recording apparatus.
