Abstract

A complex magnetic head in which magnetically separated upper and lower rank core chips are spaced apart and connected to a support block made of a nonmagnetic material in such a way as to be in parallel with each other. Each of the upper and lower rank core chips have first, second and third cores. Magnetic gaps, whose track widths are different from each other, are provided between the first and second cores of one of the upper and lower rank core chips and between the second and third cores of the other of the upper and lower rank core chips, respectively.
