Abstract

PURPOSE:To ensure the complete recording and reproduction even to a tape having high magnetic resistance, by joining the 2nd member having large electric resistance and magnetic permeability to both sides of the 1st member having high density of saturated magnetic flux. CONSTITUTION:The 2nd members 2 and 3 made of a material having large electric resistance and magnetic permeability are joined at both sides of the 1st member 1 made of a material having high density of saturated magnetic flux with 10-20mu thickness via an organic adhesive to form a block 4. This block 4 is cut right- angled to the member 1 to form a pair of core blocks 5 and 6. The cut faces 9 and 10 of the blocks 5 and 6 are polished, and a winding groove 7 extending toward the direction right-angled to the member 1 plus a gap fixing groove 8 are formed alternately to the face 10 of the block 6. Thereafter, the gap spacers are formed on the faces 9 and 10, and an adhesive 11 is filled into the groove 8 to join the blocks 5 and 6 together. The blocks 5 and 6 are cut right-angled to the faces 9 and 10 to obtain a chip 12. This chip 12 is cut with a prescribed width to form a head chip 13. Then a pair of groove parts 15 and 16 are formed on a tape touching face 14 of the chip 13.
