Abstract

PURPOSE: To obtain a magnetic head having a high accuracy and stability by formming the core block through lamination of the thin plate material and then slicing the core block after securing the gap.
CONSTITUTION: The alternating glass junction is given to magnetic thin plate 12 and ferrite block 8 containing a number of notch grooves 11 provided equidistantly in the longer orthogonal direction, and then cutting is given at positions 13W21 to obtain the lamination blocks. Then coil winding window groove 26, coil winding frame groove 27, glass sink 28 of the back part, and others are formed to the lamination block, and then the mirror surface processing is given to both gap surface 24 and its back 33 to obtain a half-body of the laminated block. This half-body is then annealed at the temperature near the yield point of the glass used for the above junction, and the generated difference of the surface level is ground to secure the smooth plane. After this, the gap spacer layer is provided to face 24, and the gap is jointed to the the haef-boly of the laminated block to be paired. This junction substance is then sliced with the polishing applied to the front surface, and then guide part 46 is eliminated to obtain the head core.
