Abstract:
A method for re-establishing a predetermined magnetic orientation of a GMR sensor in a magnetic disk drive storage system while protecting data stored therein, said method comprising the steps of:positioning said GMR sensor distant from data stored within said magnetic disk drive storage system;temporarily arming a reset pulse circuit within said magnetic disk drive storage system;activating a reset pulse only in response to a trigger signal following said arming;disarming said reset pulse circuit within said magnetic disk drive storage system following said activating of said reset pulse; andimmediately disarming said reset pulse circuit within said magnetic disk drive storage system in response to an occurrence of either a read-or-write operation within said magnetic disk drive storage system following said arming and prior to an occurrence of said trigger signal such that a reset pulse cannot be improperly initiated.
