摘要： In an optical information record medium including a plurality of record layers that are recordable, various signal characteristics with respect to an area X in a record layer A (second layer) among the plurality of record layers are defined under a condition that an area Y in a record layer B (first layer) adjacent to the record layer A (second layer) on an incident side thereof along an optical axis of a light beam shone on the area X is a prerecorded area. This suppresses variation and errors in the measurement of characteristics of various signals caused by the interfering light coming from an adjacent record layer, thereby making it possible to manage and define media parameters with characteristic values having high reliability, compatibility, and reproducibility.

摘要： A simple method for evaluating an optical information medium by judging quantitatively and reproducibly the surface quality of the optical information medium by the use of an artificial fingerprint liquid as an evaluation dispersion liquid, is provided. An optical information medium having a remarkably excellent anti-staining property of the surface which is on the incident side of recording/reproducing beam is provided. A method for evaluating an optical information medium, comprising: adhering an artificial fingerprint liquid containing a fine-particle-form substance and a dispersion medium capable of dispersing the fine-particle-form substance onto the surface of the optical information medium which is on the incident side of a recording/reproducing beam; observing the state of the artificial fingerprint liquid droplets adhered to the surface; and judging the quality of the medium surface. For example, the quality of the medium surface is judged by: (1) Measurement of the area ratio of the surface occupied with the artificial fingerprint liquid droplets adhered per unit area of the surface; (2) Measurement of the diameter of the artificial fingerprint liquid droplets adhered to the surface; (3) Measurement of the number of the artificial fingerprint liquid droplets adhered per unit area of the surface; or (4) Measurement of the degree of roundness of the artificial fingerprint liquid droplets adhered to the surface.

摘要： There is provided an optical disc reproducing method capable of reproducing a non-finalized DVD+R. When a seek operation is performed from a present address on the non-finalized DVD+R to an outer circumferential side target address, the outer circumferential direction total jump number of tracks is calculated from a difference between the present address and the target address. When a first condition is satisfied in which the present address is in an inner circumferential zone, the target address is in a second outer circumferential zone, and the outer circumferential direction total jump number is 701 to 2500, the jump number of tracks is set to 340 smaller than the outer circumferential direction total jump number, and a traverse seek using a moving mechanism to move an optical pickup in a radius direction by 340 is performed.
