A dielectric recording medium in a disc form is provided with: a center
hole; an inner area; a recording area; and an outer area, arranged
concentrically from the inside in this order. The inner area, the
recording area, and the outer area contain a uniform and flat dielectric
material and are polarized with the polarization direction of the
recording area opposite to that of the inner area and the outer area in
their initial condition. The recording area in which data is recorded has
tracks and spaces, each of which is between two of the tracks, and is
provided with areas in which control information about the
recording/reproducing is recorded, in the track and the space.
