PURPOSE: To minimize an ineffective area and to improve mounting density by tilting only a part requiring the best transfer characteristic in matching with the crystal anisotropy of a magentic film and arranging orthogonally the rest part to a major line or a major loop.
CONSTITUTION: An angle of θ=60° is given for one bit's share of a part 13 of a minor loop 12 close to the major loop 11 and other parts 14 of the minor loop 12 are arranged so as to be at a right angle (θ=90°) to the major loop 11. Fig. (b) shows the major/minor loop constitution where the major loop 11 and the minor loop 12 are abbreviated by straight lines, the ineffective region is decreased in comparison with that of conventional constitution and the high density is attained by nearly 30%.
