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.
