Abstract
A method of manufacturing a thin-film magnetic head slider suppresses the production of damaged areas during lapping, reduces the lapping time, produces high-quality products, and is suited to mass production. The method of manufacturing a thin-film magnetic head slider laps an end surface of a row bar, which has been produced by cutting a wafer substrate on which magnetic sensor parts have been formed into strips, to expose an end surface of magnetic sensor parts to a floating surface, wherein a high processing rate is set in an initial part of a lapping process that laps the row bar and a lower processing rate is set in a later part of the lapping process.
