Abstract
A read head, particularly suitable for a magnetic disc storage system, includes a read sensor having an air-bearing surface and an opposing top surface. The read head also includes a permanent magnet positioned adjacent the top surface of the read sensor for generating a magnetic bias field in the read sensor. The permanent magnet has a magnetization in a direction other than normal to the air-bearing surface of the read sensor.
