Patent ID: 7240418

Claim:
A method of manufacturing a slider of a thin-film magnetic head, the slider comprising: a slider main body having a medium facing surface that faces toward a rotating recording medium, an air inflow end, and an air outflow end; and a thin-film magnetic head element disposed near the air outflow end and near the medium facing surface of the slider main body, wherein the medium facing surface has: a first part closer to the air outflow end; a second part closer to the air inflow end; and a ridge line formed by intersection of the first part and the second part, the second part being slanted against the first part, the method comprising the steps of: forming a slider material containing a portion to be the slider main body and the thin-film magnetic head element, and processing the slider material so as to form the medium facing surface having the first part, the second part and the ridge line, and the air inflow end and the air outflow end on the slider material, wherein: the portion to be the slider main body includes: a substrate portion that has a surface facing toward the recording medium and makes a base of the thin-film magnetic head element; and an insulating portion that has a surface facing toward the recording medium and surrounds the thin-film magnetic head element; and the length of a portion of the first part in the direction of air passage, the portion belonging to the substrate portion, is equal to or less than 50% the length of the entire substrate portion in the direction of air passage.
