The present invention provides a magnetic head construction, a connection method and a connecting device by which excellent electrical connection can be carried out between a core electrode and a substrate land face on a flexure in a magnetic head employing the piggy back system. In order to attain the object of interest, in the present invention, a fine adjustment actuator is arranged between a core and a flexure; a projection portion which is projected from the fine adjustment actuator when viewed from the flexure is provided in the core; a hole is provided in the position, on the flexure, corresponding to the projection portion; only the core is fixed by a support portion provided through the hole portion and a clamp pin without applying any load to the fine adjustment actuator; and while maintaining this fixing state, an electrode and a substrate land are bonded to each other with a wire.
A magnetic head having a flexure having an electrical wiring formed therein, a fine adjustment actuator fixed to said flexure, and a core which is fixed to said fine adjustment actuator and also is electrically connected to said electrical wiring to be driven for said flexure by said fine adjustment actuator,
A device for wire-bonding an electrode formed in a core and the end portion of an electrical wiring to each other, for use in a magnetic head having a flexure having said electrical wiring formed therein, a fine adjustment actuator fixed to said flexure, and said core which is fixed to said fine adjustment actuator and is driven for said flexure by said fine adjustment actuator, said device comprising a work fixing block including a first support surface to which the rear face of the formation part of the end portion of said electrical wiring in said flexure, and the vicinity thereof are both fixed and a second support surface for supporting said core, and a work clamp pin for clamping together with said second support surface said core to fix it.
A device for wire-bonding the end portion of an electrical wiring and an electronic component to each other, for use in an electronic device including a substrate having said electrical wiring, a driving device which is fixed to said substrate in the position different from that of the formation of said electrical wiring on said substrate, and said electronic component which is fixed to said driving device to be driven by said driving device, said device comprising a work fixing block having a first support surface to which the rear face of the formation part of said electrical wiring in said substrate, and the vicinity thereof are both fixed and a second support surface for supporting only said electronic component, and a work clamp pin for clamping together with said second support surface said electronic component to fix it.
A method of wire-bonding an electrode formed in a core and the end portion of an electrical wiring to each other, for use in a magnetic head having a flexure having said electrical wiring formed therein, a fine adjustment actuator fixed to said flexure, and said core fixed to said fine adjustment actuator to be driven for said flexure by said fine adjustment actuator, said method comprising the steps of:
