Patent ID: 7283453

Claim:
A recording/reproducing head for recording information in a dielectric material of a dielectric recording medium or reproducing information recorded in the dielectric material of the dielectric recording medium, the recording/reproducing head comprising: a supporting member of a longitudinal shape which is long in one direction and which comprises first and second opposed surfaces; a projection portion disposed on one end in the one direction of said supporting member and projecting from the first surface of the supporting member toward the dielectric material; a first electrode, which penetrates a tip portion of said projection portion, for applying an electric field to the dielectric material, said first electrode extending through an opening formed in said supporting member from the second surface to the first surface thereof, and further extending to the tip portion through an opening centrally formed in the projection portion; an electric conductor portion, which is disposed on the second surface of said supporting member, for providing an electric connection with said first electrode; and a second electrode disposed on the first surface of said supporting member so as to surround said first electrode.
