PURPOSE:To shorten the magnetic path length of a head and to improve the magnetic efficiency and to realize high output and compactness by fixing the back core to the rear end of a read/write head and providing the back core with winding. CONSTITUTION:A read/write head 21 forms a U-shaped core tip having two side cores 2111 and 2112 which are connected almost at right angles to the front sliding surface and extend upward. The side cores 2111 and 2112 are connected and fixed at the rear end to a back cover 51 which is provided with a winding 31. Therefore, in comparison with those which have the side cores provided with the winding 31, the side core portion can be shortened shortening the total magnetic path length and improving the magnetic efficiency, thus promoting high output. Furthermore, the head can be made smaller because there is no projection of the winding in the side direction of the side core. |
