An optical information recording medium is provided with a plurality of information layers, each of which has a sector structure in which a data area is divided in the circumferential direction by a sector address. When an optical drive is erasing a DVD-RW disc, a write mode, instead of a conventional erase mode, is used to execute an erase operation. The storage capacitor has a multilayered structure of a first electrode, a dielectric layer, and a second electrode stacked in this order on the substrate, and the light-emitting element has a multilayered structure of a third electrode, a light-emitting layer, and a fourth electrode stacked in this order on the substrate. A short conduit connection between the control panel and the starter box is used to provide the necessary connections between the control panel and the starter box. In each nondata region, every other nondata island in the along-the track direction has the same magnetization direction, with adjacent nondata islands having antiparallel magnetization directions.
