Abstract:
A manufacturing process to manufacture a plurality of thin film magnetic head sliders comprising:providing a non-magnetic substrate wafer of not less than 5 inches in diameter and of not less than 2.5 mm in thickness, the thickness being more than a desired slider length for the magnetic head sliders of 1.25 mm, 1.0 mm or less to be manufactured;forming an insulating layer on a first end surface of the non-magnetic substrate wafer;forming a plurality of thin film magnetic head elements on the insulating layer by a thin film manufacturing process;grinding and/or lapping a second end surface of the non-magnetic substrate wafer opposite the first end surface to a thickness equal to the desired slider length of the magnetic head sliders;cutting the substrate wafer in a direction perpendicular to the first end surface of the substrate wafer to produce a plurality of row bars, each including a plurality of thin film magnetic head elements arranged in a line on a row bar surface; andmachining the row bar to form the plurality of thin film magnetic head sliders.
