Abstract
A thin-film magnetic head has at least either an electromagnetic transducer or a magnetoresistive device, and a sheet-shaped heater for generating heat when energized. The heater has a heating part and a lead part connected in series to the heating part. The lead part has a sheet resistance lower than that of the heating part.
