Abstract
An apparatus is disclosed which mechanically supports and electrically connects a magnetic field modulation head for opto-magnetic recording to a supporting/connecting device. The magnetic field modulation head is in slidable contact with a surface of an opto-magnetic disc and is placed face-to-face with a laser pick-up device. The apparatus has a connecting spring member made of a conductive material. The connecting spring member has one end which joins a coil of the magnetic field modulation head with a coil of the magnetic field modulation head, and an opposite end which is fixed on a supporting member. The spring member has a pair of conductive pieces spaced apart from each other. The conductive pieces are made of a material which renders the coil conductive with the supporting member, the one end and the magnetic field modulation head being embedded in a composite resin material. To partially mechanically engage the conductive pieces together, an insulating engaging member may be used. Alternatively, the spring member may have a pair of conductive pieces spaced apart from each other and placed on a single insulating plate made of a flexible composite resin.
