ABSTRACT:
A disc device accommodates a disc rotatably mounted therein, a plurality of first heads movable in a first direction radially of the disc, and a plurality of second heads movable in a second direction radially of the disc and perpendicular to the first direction. The disc has a first surface and a second surface opposite to each other, with an information area defined on at least one of the first and second surfaces. The information area is divided into an outer information region and an inner information region lying radially inwardly of the outer information region. The first heads are allowed to move within a limited distance across the outer information region so as to record or reproduce information on or from the outer information region, while the second heads are allowed to move within a limited distance across the inner information region so as to record or reproduce information on or from the inner information region.
