Claims

[Scope of utility model registration request]

In a magnetic head consisting of a head chip in which a pair of plate-shaped magnetic cores are joined and a gap is formed at the joined part, and substrates 1 and 10 fixed to both sides of the head chip, the pair of magnetic heads constituting the head chip are The magnetic cores 2 and 20 are superimposed and fixed on each other in a plane substantially parallel to the plane including the gap part, and the head of each magnetic core is formed to have a narrow width according to the track width, and the head is different from the head. The end of the magnetic core on the opposite side is formed to have a wide width, and at least one of the pair of magnetic cores has a shaft portion 3 protruding toward the other magnetic core at the wide portion, and a coil device 5 is attached to the shaft portion 3. The substrates 1 and 1 are wound on the head chip on both sides of a plane including the gap portion in parallel with the plane.
10, the coil device 5 includes a base film 7 made of an insulating material, and a base film 7 made of an insulating material.
It is composed of a plurality of coil layers 51 to 55 formed on top of each other and electrically connected to each other, and each coil layer is
A strip-shaped conductor pattern 81 that extends around the shaft portion 3
~85 and an insulating film 71 covering the conductor pattern
73, wherein the respective conductor patterns of the pair of upper and lower coil layers adjacent to each other are formed in shifted positions so as not to overlap with each other.
