- - HIGHLY SENSITIVE SPIN VALVE HEADS USING A SELF-ALIGNED DEMAG-FIELD BALANCE ELEMENT

摘要

The magnetic data storage, and magnetic read head 30 for use in the recovery system, the first current contact 40, a second current contact 42, the magnetoresistive read sensor 34, and the demagnetization field balance element (50) have. Both are of the magnetoresistive read sensor 34 and the demagnetization field balance element 50 is located between the first and second current contacts 40 and 42. Demagnetization field balance element 50 is electrically insulated from the magnetoresistive read sensor (34) and is coupled magnetically.
