METHOD OF PROTECTING HARD DISK DRIVE FROM SHOCKS, HARD DISK DRIVE, METHOD OF IMPROVING SHOCK RESISTANCE OF HARD DISK DRIVE, AND APPARATUS FOR PREVENTING HARD DISK DRIVE FROM BEING SHOCKED

摘要

PROBLEM TO BE SOLVED: To provide a method of protecting a hard disk drive from shocks and a hard disk drive suitable therefor.;SOLUTION: A method of protecting a hard disk drive from shocks includes the steps of: reading servo signals from a rotating disk using a head that follows tracks on the disk; detecting an amount of jitter in the servo signals; comparing the detected amount of jitter with a predetermined threshold amount of jitter corresponding to a movement great enough to damage the head and the disk; and unloading the head if the detected amount of jitter is greater than the predetermined threshold amount of jitter.;COPYRIGHT: (C)2006,JPO&NCIPI
