A system for lapping transducers (28) has an abrasive surface (22) that communicates with the transducers to provide information for controlling the lapping of the transducer. The lapping body (20) communicates with a transducer (28) with a signal that the transducer is designed to read or write. For lapping a magnetic head or slider, the lapping body contains a magnetic medium layer (23) that is prerecorded or written by the head during lapping, while the signal received by the head is monitored by a processor (32) in order to terminate lapping. |
