Abstract:
A method of making rows and columns of sliders on a wafer substrate wherein each slider has a respective magnetic head component within a perimeter of the slider comprising the steps of:forming a mask on the wafer substrate that masks a perimeter portion of each of a plurality of slider sites of said sliders and a perimeter portion of a magnetic head component site of said magnetic head component within a respective one of each of said plurality of slider sites;plating a ferromagnetic thin film layer on the wafer substrate at the magnetic head component sites to form magnetic head component portions of the ferromagnetic thin film layer and to form a field portion of the ferromagnetic thin film layer about each magnetic head component site that is located between a mask perimeter portion about the magnetic head component site and a mask perimeter portion that is about a respective slider site;removing the mask at said perimeter portions leaving discrete sliders wherein each slider has a respective field portion that is disconnected and separate from field portions of adjacent sliders and a discrete magnetic head component portion within each respective field portion that is disconnected and separate from the respective field portion; andsimultaneously lapping the field portions and the magnetic head component portions for planarizing the field and magnetic head component portions.
