Abstract:
A method of making a magnetic head that has an air bearing surface (ABS) comprising the steps of:providing a wafer; forming a strip of photoresist on the wafer at an ABS site of said ABS with a width that defines a track width of the magnetic head and with a height above a desired height of a second pole tip which is to be formed; forming a forming layer on the wafer and on the strip with a thickness above the wafer that is equal to or greater than a desired height of the second pole tip which is to be formed; mechanically polishing the forming layer until the strip is exposed; removing the strip leaving a second pole tip opening in the forming layer at said site for the second pole tip which is to be formed; forming the second pole tip which is to be formed in the second pole tip opening; and continuing said mechanical polishing until the second pole tip is at a desired height wherein said desired height is along a height line that lies within a plane of said ABS and is perpendicular to a width line along said track width.
