Abstract: The reflected light amount acquiring process acquires the reflected light amount of a laser beam with which a color changeable layer is irradiated from at least one irradiation position included in a predetermined drawing determination area, where the color changeable layer is formed on a label side of an optical disc and changes in color due to heat or light. The operation process compares the reflected light amount acquired from the at least one irradiation position by the reflected light amount acquiring process with a predetermined threshold value to determine whether or not the drawing determination area is suitable for formation of a visible image.

Abstract: An object of this invention is to measure the tilt quantity of, and perform a tilt control on, an optical disc accurately without depending on the rotation control method.An optical disc drive includes: a motor for rotating an optical disc; an optical system for irradiating the optical disc with a light beam; a moving mechanism for moving the optical system along the radius of the optical disc; a focus control section for controlling movement of the optical system perpendicularly to the optical disc based on drive values, thereby focusing the light beam onto a storage layer of the optical disc; and a tilt control section for measuring the tilt quantities of the storage layer at multiple different radial locations on the optical disc based on drive values for the respective radial locations when the focus control section focuses the light beam there. When the tilt control section measures the tilt quantities, the motor keeps the rotational frequency of the optical disc constant and the tilt control section uses the drive values obtained at the respective radial locations.

Abstract: A center site is disposed to intervene in a business transaction achieved through a network. The center site includes an open business information database in which open business information received from member sites connected to the network is accumulated to be opened to the sites and a notarization database to keep therein contents of contracts of transactions between the sites. The center site receives a transaction request from a transaction partner site in accordance with the open business information and notifies the request to an information supply site associated therewith. The center site intervenes in a transaction resultantly accomplished between the information supply site and the transaction partner site and conducts a notarization process for the contents of contract for the transaction to accumulate the contract in a notarization database.

Abstract: The optical disc apparatus according to the present invention includes a tilt detecting means; a coma aberration correcting means; and a spherical aberration correcting means. Based on the result of a tilt detection, the amount of the correction performed by the coma aberration correcting means is determined so that the amount of correction is constant for the whole circumference of an optical disc, and then a spherical aberration is corrected by the spherical aberration correcting means. Thus, it is possible to correct the spherical aberration that has occurred due to the coma aberration correcting means, while the tilt margin is secured, thereby improving the reliability of reproduction and recording by the optical disc apparatus. Further, the optical disc apparatus according to the present invention is configured, in the case where a thermal shock tilt has occurred during the activation of the apparatus, to wait until the thermal shock tilt has settled. Thus, it is possible to perform the activation while the influence of the thermal shock tilt is avoided, thereby improving the reliability of the recording and reproduction operations by the optical disc apparatus.
