Abstract: An air bearing slider assembly includes a U-shaped magnetic head and a monolithic glass body which is formed in the glassy state so as to chemically as well as physically bond the head thereto, a nonmagnetic gap in the base of the head being disposed at an air bearing surface of the glass body to facilitate noncontact magnetic recording. The slider assembly is fabricated using a mold having a central cavity which defines the desired configuration of the glass body and which positions the magnetic head at a selected location relative to the glass body to be formed. The mold cavity is filled with a fluid glass composition which solidifies as a monolithic body in bonded relation to the head.

Abstract: A GLASSING METHOD FOR JOINING A FERRITE RECORDING HEAD TO A CERAMIC SLIDER BY THE STEPS OF FILLING THE RECORDING HEAD GAP WITH A DEVITRIFIABLE GLASS AND CRYSTALLLIZING THE GLASS SO AS TO EFFECTIVELY RAISE ITS SOLTENING POINT AND HARDNESS; ADDING A SECOND GLASS MATERIAL TO THE SLIDER AREA TO WHICH THE HEAD IS TO BE JOINED, PLACING THE HEAD IN CONTACT WITH THE SLIDER, AND HEATING THE SECOND GLASS MATERIAL TO A TEMPERATURE SUFFICIENT TO JOIN THE HEAD TO THE SLIDER. THE SLIDER GLASS MATERIAL IS PREFERABLY ALSO THE SAME DEVITRIFIABLE GLASS MATERIAL AS USED WITH THE HEAD, AND MAY BE HEATED TO THE DEVITRIFYING TEMPERATURE. THIS LATTER SCHEME ALLOWS ONE GLASS SYSTEM TO BE EMPLOYED FOR MULTISTEP PROCESSES AT ONE COMMON LOW TEMPERATURE. REDUCED CORROSION AND IMPROVED WEAR CHARACTERISTICS ARE REALIZED.
