摘要

The present invention generally relates to a magnetic sensor in a read head having a hard or soft bias layer that is uniform in thickness within the sensor stack. The method of making such sensor is also disclosed. The free layer stripe height is first defined, followed by defining the track width, and lastly the pinned layer stripe height is defined. The pinned layer and the hard or soft bias layer are defined in the same process step. This approach eliminates a partial hard or soft bias layer and reduces potential instability issues.
