Filed: 1979-07-30
Abstract: PURPOSE:To avoid the damage of the magnetic head whose slider and core surfaces are made of different materials, by giving a simultaneous polishing to both the slider and core surfaces on the surface plate having a level difference and thus securing a level difference between the slider and core surfaces. CONSTITUTION:Slider surface 8, flow-in end slope 9 and groove 10 into which the core is buried and provided to slider part 7 made of the Al component for the monolithic magnetic head of the magnetic disk pack device. Core 11 made of the Mn- Zn ferrite or the like has core width 12 mimultely smaller than groove 10 and is then adhered close to the surface of alumina jig 16 having level difference 15 of about 5-10mu via thin film 14 and with core surface 13 and slider surface 8 turned down. Then two pieces of glass rod 17 are put at the junction part between slider 7 and core 11 and then melt-stuck by the heat treatment. After this, surface 13 is shaved off to obtain core surface width 13 a little smaller than the finished width. Then the lapping is given on surface plate 19 via diamond abrasive grain 20 until surface 13 becomes at the same level of surface 8. Then a simultaneous lapping is given to both surface 13 and 8 on plate 19 containing Al film 21 in order to secure level difference 23 nearly identical to the thickness of the thin film.
