PURPOSE:To reduce the number of parts to improve the yield by burying a head unit in a housing consisting of a resin composition containing a wear resisting filler. CONSTITUTION:A joined body of a read-write core 21 consisting of a ferrite or the like and a supporting body 85 consisting of nonmagnetic ceramics like a barium titanate is laminated with joined bodies of erase cores 251 and 252 and supporting bodies 811 and 812, which consist of the same kind of materials, between them. Windings 31 and 35 are wound around these cores, and back bars 51 and 55 are provided, and this head unit is adhered to a housing. The housing 7 is a truncated quadrangular pyramid having a flat sliding surface 11 and a groove 115, and an insertion hole 25 of a cavity part for head unit insertion is provided on the sliding surface 11, and the head unit is inserted to this insertion hole 25 and is adhered. The groove 115 is formed on the sliding surface 11 for the purpose of reducing friction, and a plate 9 is stuck to the rear end face of the housing 7. |
