Abstract

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.

Therefore, when the magnetic head 1) 1 is used, both sides of the recording track are in a power dopant state with almost completely no signal, so even if the track spacing is increased to increase the recording density, adjacent tracks will not be tracked during playback. Since no crosstalk occurs, it is possible to relatively easily cope with high track densities of 100 tracks/inch or more.

By the way, when joining the first head element part (21) and the second head element part (31), in order to prevent mutual interference, the first head element part (21) and the second head element part (31) are bonded together.
It is necessary to provide a predetermined interval between the second head element portions (2H31). There are two ways to provide this interval, for example, as shown in FIGS. 10 and 1. A spacer U of a predetermined thickness is sandwiched and temporarily bonded to both ends of the joint surface of the second head element part (2+131), and then a low melting point glass rod (19a) is placed in the groove part a9.
