Abstract: An air bearing slider assembly includes a three-piece ceramic body held together by glass bonds and a magnetic head rigidly mounted by glass within a slot in the body and presenting a nonmagnetic gap at an air bearing surface of the body to facilitate noncontact magnetic recording. The body of the slider assembly is made by separately molding the three ceramic pieces, finishing the surfaces on one of the pieces which later support the magnetic head, and heating glass frit between surfaces of the pieces to a fluid to bond them together. Completion of the slider assembly is then accomplished by positioning the head against the supporting surfaces and within a slot in the formed body, filling the slot with a fluid glass composition to bond the head to the body, and finishing an air bearing surface of the body and included nonmagnetic gap of the head.
