Abstract

PURPOSE:To prevent a crosstalk caused between tracks, by setting a pair of blocks made of magnetic and nonmagnetic matters opposite to each other to joint them into a body and at the same time forming a winding groove plus a cut part reaching the winding groove at one of the blocks. CONSTITUTION:A block 13 formed by laminating the magnetic plates 11 and nonmagnetic plates 12 alternately is cut to obtain lamination blocks 14a and 14b. Then a winding groove 15 is formed to the block 14a, and a nonmagnetic thin film 16 set to the size of a gap (g) is formed on the opposite surface of at least either one of the blocks 14a and 14b. The blocks 14a and 14b are joined into a body by means of the glass, and a cut part 18 is formed at a part of a nonmagnetic part 12a of the block 14a containing the groove 15. The part 18 is formed from the side opposite to the groove 15 and in the direction vertical to the groove 15 to reach the groove 15 with an optional width. Then an energizing winding 19 is applied to both the groove 15 and the part 18.
