Abstract:
1. A method of lapping a medium-opposing surface of a thin-film magnetic head, the method comprising the steps of: preparing a magnetic head bar in which thin-film magnetic heads are arranged in a row, each of the thin-film magnetic heads including a magnetoresistive device for reproducing, an inductive electromagnetic transducer for recording, a heater for generating heat when energized, the heaters in the respective thin-film magnetic heads being electrically connected to their neighbors in series; connecting a variable resistor to each of the heaters in parallel; varying resistance of each of the variable resistors depending on an amount that the medium-opposing surface of the thin-film magnetic head is to project; polishing the medium-opposing surface of the thin-film magnetic head in the magnetic head bar while energizing the heaters.
