发明名称 METHOD AND APPARATUS FOR CONTROLLING FLY-HEIGHT OF A PERPENDICULAR-MAGNETIC-RECORDING HEAD IN A HARD DISK DRIVE
摘要 A method for controlling proximity of a read element of a perpendicular-magnetic-recording (PMR) head to a PMR disk. The method includes: a) writing recorded data with a write element of the PMR head to the PMR disk; b) providing a proximity-control setting to a proximity-control element; c) positioning the read element of the PMR head with the proximity-control element as determined by the proximity-control setting in communication with the PMR disk for reading recorded data back from the PMR disk; d) measuring a resolution of a read-back signal of recorded data on the PMR disk associated with the proximity-control setting; e) determining if the resolution measured for the read-back signal of recorded data on the PMR disk satisfies a criterion for the resolution of the read-back signal of recorded data; and, f) changing the proximity-control setting, and repeating b), c), d) and e), unless the resolution satisfies the criterion.
