摘要： In an optical disk, a substrate has main data recorded in the form of a combination of pits and lands on one side thereof, and at least a reflective layer and cover layer are stacked on the substrate to cover the pits and lands on the substrate. To the optical disk, sub data is recorded in the form of marks formed by irradiating writing-power laser light to the reflective layer. The marks are formed so that reading signal level will be raised where the marks are formed while it will be lowered where the marks are formed in a counterfeit disk produced based on an authenticated disk, namely, the reading signal level where the marks are formed is different in polarity between in the authenticated and counterfeit disks. Further, in a player for the optical disk, discrimination is made between the authenticated and counterfeit disks by detecting the sub data recorded in the optical disk and judging whether the value of the detected sub data has been read at a correct polarity.

摘要： A method for manufacturing a microlens includes forming a microlens by pressing a microlens mold having a reverse shape of a microlens formed therein on a microlens-forming film formed on a substrate to transfer the reverse shape of the microlens to the microlens-forming film. The microlens mold is formed by irradiating an inorganic resist film which is formed on a mold substrate with exposure light by relative two-dimensional scanning, and etching an exposed region of the inorganic resist film to form the reverse shape of the microlens. The irradiation intensity of the exposure light is adjusted to correspond to the depth of the reverse shape of the microlens from the surface of the inorganic resist film on the basis of profile data of the reverse shape of the microlens.

摘要： The recording accuracy of information on an optical disc is increased.An information optical system (150) of an optical disc apparatus (110) enables a semiconductor laser (3) to sequentially output specific peak light (LEP) and specific slope light (LES) as an information light beam (LM) and enables the correction lens (162) to change the divergence angle of the specific peak light (LEP) so that an absorption change area (RA) by the specific peak light (LEP) can be positioned at a far position in the recording layer (101). Thus, it is possible to form an energy concentration area (RE) by the specific slope light (LES) in the vicinity of a target position (QG), and the recording accuracy of information on the optical disc (100) can be increased.
