Patent ID: 7276173

Claim:
A method of producing a dielectric recording medium for recording information in a dielectric material, the method comprising: a mask formation process of forming a mask on a first surface of the dielectric material to cover a recording area with the mask; a first etching process of etching the first surface of the dielectric material to remove a predetermined amount of the dielectric material located in an area which is not covered with the mask; a mask removing process of removing the mask from the first surface of the dielectric material; a conductor formation process of forming a conductive thin film over the whole of the first surface of the dielectric material; a bonding process of bonding the first surface of the dielectric material over which the conductive thin film is formed to a bonding surface of a substrate; and a second etching process of etching a second surface of the dielectric material which is on the opposite side to the first surface.
