である。 That is, as shown in FIG. 3a, first, a groove 2 corresponding to the track width and a groove 3 serving as a winding window are formed in a rectangular parallelepiped block 1 made of ferrite magnetic material, and then an amorphous film is formed in the groove 2 etc. by sputtering means or the like. A rectangular parallelepiped block 1 is provided with a magnetic material 4 (FIG. b), and the grooves 2 and the like are filled with the amorphous magnetic material 4.
The surface side on which the amorphous magnetic material is formed is flattened by mirror wrapping (FIG. 1 c), and then track width regulating grooves 5 are formed (FIG. 1 d), and the winding wire described in the process of FIG. A rectangular parallelepiped block 1' produced through the same process as explained in FIGS. 1 a to d without forming the groove 3 serving as a window, and the above-mentioned FIGS. 1 a to d
The rectangular parallelepiped block 1 created through the process described above is butted against each other so that the amorphous magnetic materials face each other, and the hole consisting of the track width regulating groove is filled with low melting point glass 6, and heated and pressed to form a rectangular parallelepiped. Blocks 1 and 1' are joined and integrated to form a composite block 7 (Fig. 1e), and the composite block 7 is sliced along the virtual plane shown by the dashed line in Fig. 1e, and the tape sliding surface side is sliced into a predetermined shape. By forming the magnetic head 8 into the shape shown in FIG.
しかし、このようにして制造される磁気ヘツド
は、トラツク巾規制用の溝５に充填されるガラス

かも再生出力等が充分でなく、再生特性に低下が
みられる等の欠点がある。 However, the magnetic head manufactured in this way has poor wear resistance and is easily scratched because the glass filled in the track width regulating groove 5 has a low melting point. The corrosion resistance is not good, the life of the magnetic head is short, and furthermore, the reproduction output is not sufficient, and the reproduction characteristics are deteriorated.

られないという欠点があるのである。 Therefore, it may be possible to use a glass with a high melting point to fill the grooves for regulating the track width, but when molding the glass, it is impossible to mold the glass at a temperature exceeding the crystallization temperature of the amorphous magnetic material 4. Due to these constraints, the above-mentioned drawbacks cannot be solved by the technical concept of simply using glass with a high melting point. That is, the above-mentioned manufacturing process has a drawback in that even if it is desired to use glass with a high melting point to fill the track width regulating grooves, it cannot be used.
