ABSTRACT:
An optical information storage medium includes a light transmitting layer, a first information storage layer, an intermediate layer mainly made of resin, a second information storage layer, and a substrate. The light transmitting layer, the first information storage layer, the intermediate layer, the second information storage layer, and the substrate are layered in this order from a reproduction light incident side. Each of the first information storage layer and the second information storage layer includes: a light absorbing film that absorbs reproduction light to generate heat; and a reproduction film that is heated by the heat generated by the light absorbing film so as to reproduce a signal shorter in mark length than a resolution limit of an optical system of a reproducing apparatus.
