Patent ID: 7146714

Claim:
A method of manufacturing a magneto-optical write and/or read head, the method comprising the acts of: providing a coil substrate having substantially parallel main surfaces including an outwardly directed surface and an opposed top surface, interconnected by a side surface; depositing a coil on the outwardly directed surface of the coil substrate comprising a continuous electrical conductor pattern with a coil lead in sections a coil winding section and a coil lead out section; providing means for contacting the coil by electrically connecting the coil lead in and lead out sections to external lead in and lead out lines; extending the coil lead in and coil lead out sections to an interconnection part of the side surface of the coil substrate; depositing a pattern of respective first and second interconnecting conductors on the interconnection part of the side surface in electrical connection with the lead in and lead out sections respectively for contacting the external lead in and lead out lines respectively such that a lead in conductor is formed comprising the first interconnecting conductor and the lead in section of the coil respectively, and a lead out conductor is formed comprising the second interconnecting conductor and the lead out section of the coil, respectively; providing an auxiliary substrate having a supporting surface and an adjoining auxiliary side surface; after depositing the coil on the outwardly directed surface of the coil substrate but prior to the acts of depositing the interconnecting conductors on the interconnection part of the side surface of the coil substrate, detachably arranging the coil substrate on the supporting surf ace of the auxiliary substrate in a position such that the coil is directed to the supporting surface and the interconnection part of the side surface of the coil substrate is flush with the auxiliary side surface of the auxiliary substrate; providing a mask over at least a part of the interconnection part of the side surface such that areas for disposing the interconnecting conductors remain exposed areas; depositing a layer of conducting material over at least a part of the mask and over the exposed areas; removing the mask so that the pattern of spaced interconnecting conductors remains on the interconnecting part of the side surface of the coil substrate; and detaching the coil substrate from the auxiliary substrate.
