发明名称 PRODUCTION OF MAGNETIC HEAD
摘要 PURPOSE:To control conveniently and with high precision the interval between both head element parts by regulating the thickness of an adhesive member. CONSTITUTION:An adhesive member 40 is used as a spacer member consisting of a high-melting material, and a glass insertion groove 42 is formed by grooving a ceramic member 41 of high-density MnZn ferrite identical to a head core material. Lead-boric acid low-melting glass 43 is placed on the groove 42, a ceramic plate 44 is placed on the vertical end surface 41a of the opening part of the groove 42 to prevent the outflow of glass, the glass 43 is heated at 500 deg.C for 1hr and melted while exerting hydrostatic pressure in the lengthwise direction of the groove 42 to bond the ceramic material 41 and the glass 43, and a ceramic/glass bonded body 45 is formed. The adhesive member 40 thus formed is interposed between the second head core 22 and the third head core 28, and heated at 450 deg.C for 10min to melt the glass 43. Consequently, both head members are bonded while leaving a specified interval between the first head element part 2 and the second head element part 3.
