  • Method and apparatus for error recovery for unstable magnetorestrictive heads
    Patent number: 5661614
    Abstract: A method and apparatus is disclosed for recovering data with unstable low amplitude magnetorestrictive heads. After an error in data recovery is detected a technique is invoked that changes the bias current through the magnetoresistive head to the reverse direction in a predetermined manner. The method includes reversing the bias current direction, returning the bias current to its normal state and reading the data from the storage medium. Alternatively, the method includes reversing the bias current direction and reading the data when the bias current direction is reversed.
