Abstract:
A station for performing a lapping method to achieve tight dimension controls for both read and write elements of magnetic recording heads is disclosed. A recording head having a read head stripe height and a write head throat height is lapped using a plurality of lapping forces. At least one of the plurality of lapping forces includes a torque force. A lapping wedge angle is controlled using at least one torque force, which controls the offset between the recording head read head stripe height and the write head throat height.
