A dielectric recording medium is provided with three layers of: a
dielectric material, an electric conductor, and a substrate, and has a
groove on the recording surface of the dielectric material. The groove is
provided with one or a plurality of grooves. When a voltage is applied to
a probe, the dielectric material just under the probe is polarized
depending on an electric field generated between the electric conductor
and the probe, which allows recording. Moreover, the groove facilitates
the probe tracking since the probe scans along this groove.
