摘要： An opto-magnetic recording medium such as an optical disk or an optical card and its manufacturing method, and an opto-magnetic recording/reproducing device for recording/reproducing information on/from an opto-magnetic recording medium. The opto-magnetic recording medium has recording and reflecting layers on a substrate. The recording layer has a layered structure of at least one spinel ferrite (or rutile oxide or hematite) layer and at least one garnet ferrite layer. The layered structure is preferably formed on a track where information is to be recorded. A method of manufacturing such an opto-magnetic recording medium comprises a step of heating the medium at 500 °C to 700 °C, preferably at 600 °C to 630 °C after the recording medium is formed. The opto-magnetic information recording/reproducing device is preferably used for such an opto-magnetic recording medium because the wavelength of the light for write is different from that of the light for read.

摘要： A simple method of evaluating an optical information medium, which judges quantitatively and reproducibly whether the surface of an optical information medium is acceptable or not by using a novel artificial finger-print liquid that is an evaluating dispersion liquid. A method of evaluating an optical information medium comprising the steps of depositing on the surface, on the recording/reproducing beam incident side, of an optical information medium an evaluating dispersion liquid containing a fine-particle-like material and a dispersion medium capable of dispersing the fine-particle-like material under a specific condition, measuring an area ratio that an evaluating dispersion liquid droplet deposited per unit area of the surface accounts for, and judging it to be acceptable when the measured area ratio is up to 6%. A method of evaluating an optical information medium comprising the steps of depositing on the surface, on the recording/reproducing beam incident side, of an optical information medium the above evaluating dispersion liquid under a specific condition, measuring recording/reproducing characteristics (e.g., error rate) with the an evaluating dispersion droplet kept deposited on the surface, and judging it to be acceptable if the measured recording/reproducing characteristics are equal to or better than a specified value.

摘要： Without annealing an optical storage medium (4), annealing management information (40-1) is recorded in an annealing management area (40) of the optical storage medium, and the optical storage medium is provided to a user. When the user selects annealing of the optical storage medium, high-density recording /reproduction can be performed thanks to the annealing effect of the area between recoding tracks. By eliminating the annealing, the storage medium manufacturer can provide a medium at a low price. Since it is unnecessary to deepen the groove of the substrate used for the medium, the manufacture of the substrate is easy. If advertisement information is recorded in a pit portion of the area to be annealed, the advertisement information can be reproduced during annealing, and the medium price can be supplemented by the advertisement expenditure.

摘要： To provide a method of testing an information recording medium (10) based on the effects of fingerprints attached to an incident surface (13a) on the signal characteristics. A step (S12) of attaching an artificial fingerprint to an incident surface (13a) of an information recording medium (10), a step (S13) of reproducing a signal recorded in an attached region to which the artificial fingerprint has been attached, and a step (S14) of judging whether the information recording medium (10) is defective or non-defective based on a signal quality of the reproduced signal are carried out. By doing so, the information recording medium (10) for which the signal quality of the reproduced signal remarkably deteriorates due to fingerprints adhering to the incident surface (13a) can be rejected as substandard, and the distribution of such information recording medium (10) onto the market can be avoided. As a result, it is possible to sufficiently ensure the reliability of the information recording medium (10) that is to be used as bare discs in particular.
