Abstract

A magnetic unit according to the present invention has a recess formed in a plate which is capable of accomodating terminals, FPC and conductive joining member, thus preventing the terminals, the conductive joining member, and the like from projecting out in the direction of thickness of a magnetic head, and consistently preventing short circuits in the terminal portion from occuring by preventing contact of the terminals and a base, as well as allowing thinner magnetic head units and FDDs to be produced. A ground circuit pattern portion formed on the FPC and the core are directly connected, such that even when a carriage having a gimbal plate mounted thereto is formed from a metal, no insulating sheets are required, which allows grounding of a magnetic core to be appropriately carried out at an electrical potential different from that of a chassis. In addition, no insulating members and the like are required, unlike conventional magnetic head units, thereby decreasing the number of parts to be used and allowing thinner magnetic head units to be produced. With the periphery of the FPC in a bent state, since the terminals and the circuit pattern can be connected, the occupying area can be decreased with respect to the gimbal plate of the FPC, allowing smaller gimbal plates and smaller magnetic head units to be produced.
