Method for detecting mechanical damage in a parking zone of a hard disk drive
摘要:
A method for detecting an asperity in a non-data parking zone of a disk in a hard disk drive. The method includes the steps of moving the heads of the disk drive adjacent to the parking zones of the disks, and then detecting asperities in the parking zones with a thermal asperity detection circuit.
