Abstract

PURPOSE: To realize an easy manufacture for the magnetic head having a desired track width by forming core blocks through lamination of the nonmagnetic base plate and the sendust thin plate of the desired thickness and thus omitting the finishing work for the track width which is to be given in the final process.
CONSTITUTION: Nonmagnetic base plate 2 and sendust thin plate of the desired thickness are laminated via soldering. Then this lamination is cut at the dotted lines to obtain lamination blocks 4 and 8. Winding groove 5 is formed to block 4, and gap forming surface 6 is polished into the mirror surface along with spacer material 7 stuck to the mirror surface. While gap forming surface 9 is polished in the same way into the mirror surface with spacer material 10 stuck to block 8. After this blocks 4 and 8 are adhered together via the 2nd soldering material having the lower fusing point than the 1st soldering material, and then cut at about intermediate positions (dotted lines) of base plate 2 into plural units of chips. And then the front surface of chip 11 thus obtained is polished into the prescribed curvature, and the coil is wound through winding groove 5. Thus a magnetic head is obtained.
