ABSTRACT:
A magnetoresistive head apparatus includes first and second readers. The first reader is a magnetoresistive reader. The second reader provides electrostatic discharge protection for the first magnetoresistive reader. The second reader can be a second magnetoresistive reader having substantially the same film structure as the first reader. The second reader can also include a phase change thin film, which has high and low resistance states that are changeable using a laser.
