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 includes: a medium information region on which medium identification information is recorded; a content region on which content information is recorded; and a blank region provided between the medium information region and the content region and in which at least two tracks are provided so as to connect a train of prepits in the medium information region and a train of prepits in the content region. No information is recorded on the blank region. Thus, a super-resolution optical recording medium is provided 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： A super resolution medium (1) is provided with an information signal region (11) where a content, such as a video or audio content, is recorded and a test read region (12) where reproduction setting value adjustment information is recorded for adjusting a setting value for reproduction. A shortest mark length on a first prepit row formed in the information signal region (11) is shorter than a length of an optical system resolution limit of a playback apparatus. The types of mark lengths, recorded in the test read region (12), on the second prepit row for adjusting the setting value are the same as part or all types of mark lengths on the first prepit row. Further, the second prepit row includes a prepit having a mark length shorter than the length of the optical system resolution limit of the payback apparatus. Still further, each of the first and second prepit rows has at least three types of mark lengths. With this arrangement, optimum reproduction can be performed for each medium in the super resolution medium (1).
