摘要： This invention allows super-resolution reproduction with which a better bER value is attainable, when information is recorded by a random pattern including a mark length not longer than a resolution limit, by use of a highly versatile signal decoding method.Information is recorded as marks and spaces coded by RLL(1, 7) modulation, which each of the marks and spaces have one of a plurality of lengths, and 2T marks and 2T spaces of the marks and spaces being formed are shorter than 0.12 μm. An information recording layer (20) includes a reproduction film (21) and a reflective film (22) which are provided in this order from a side from which reproducing light is incident, which reproduction film is made of (i) zinc oxide, (ii) strontium titanate, (iii) titanium oxide, (iv) cerium oxide, or (v) a material including at least one of the (i) through (iv), and which reflective film is made of tantalum or titanium.

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： 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 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).

摘要： There is provided a storage layer (13) between storage layers (11), (15). The storage layer (13) produces a relatively large spherical aberration for a protection layer thickness error. Information is written to or read from the storage layer (13) with a beam of light having a second wavelength. Information is written to or read from the storage layers (11), (15) with a beam of light having a first wavelength (longer than the second wavelength). Accordingly, a multi-format optical storage medium is realized on which information can be recorded or reproduced with a single objective lens. Also, an optical pickup is realized which is capable of recording or reproducing information on the multi-format optical storage medium.
