PURPOSE:To obtain a magnetic head suitable for high density recording by imbedding a nonmagnetic material having a large deflective strength passing through a filling glass imbedded in a groove for restricting track width and connected to a reproducing core so as to increase the strength of the core and to improve the yield. CONSTITUTION:The track width of a head is specified by grooves formed by groove processing to a recording/reproduction C-shape core 10, a recording/ reproduction I-shape core 11, an erasure C-shape core 13 and an erasure I-shape core 14 respectively and a filling glass 16 is filled to the grooves. The cores are connected by a reinforced ceramic 20 and sliders 21, 22 provided smoothly in slide contact with a recording medium are adhered. Thus, the adhering strength of the cores is increased much and the head corresponding to highly accurate recording is obtained with good yield.
