ABSTRACT:
A disk includes a perpendicular recording disk, a head having a read portion to read information recorded on the perpendicular recording disk, a sensor in the read portion, and a coil structure, coupled to the read portion, to provide bias flux to the sensor. The coil structure may include two coils.
