Method of manufacturing ferrite recording heads with a multipurpose devitrifiable glass
Abstract
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. D R A W I N G
