摘要： In an optical information recording medium (1), a light-transmitting layer (10) or a transparent substrate, an information recording layer (20), and a substrate (30) are stacked in this order from a side from which reproducing light (2) enters. The information recording layer (20) includes at least a reproducing film (21) whose complex refractive index at a light source wavelength (λ) of the reproducing light (2) is changed by heat. The relationship of 0.67×(λ/NA)>TP>0.04×(λ/NA) is satisfied, where TP is a track pitch of prepits (31) formed on the substrate (30), and NA is a numerical aperture of an objective lens (55) for converging the reproducing light (2) on the optical information recording medium.

摘要： A super-resolution optical recording medium (10) of the present invention includes: a medium information region (1) on which medium identification information is recorded; a content region (3) on which content information is recorded; and a blank region (2) provided between the medium information region (1) and the content region (3) and in which at least two tracks are provided so as to connect a train of prepits in the medium information region (1) and a train of prepits in the content region (3). No information is recorded on the blank region (2). With this arrangement, the present invention provides a super-resolution optical recording medium in which a region on which medium identification information is recorded and a region on which content information is recorded are different in track pitch and in which a reproduction error hardly occurs when reproduction shifts from the region on which the medium identification information is recorded to the region on which the content information is recorded.

摘要： 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.
