    摘要: A method for inspecting an optical information storage medium includes irradiating the medium with a laser beam and rotating the medium by a constant linear velocity control technique by reference to the radial location at which the laser beam forms a spot on the medium; changing the rotational velocities according to the radial location on the medium between at least two linear velocities; generating a focus error signal and/or a tracking error signal based on the light reflected from the medium; performing a focus control and/or a tracking control on the laser beam based on the focus and/or tracking error signal(s); and passing the branched outputs of control loops for the focus and/or tracking error signal(s) through predetermined types of frequency band-elimination filters to obtain residual errors of the focus and/or tracking error signal(s) and comparing the residual errors to predetermined reference values.

    摘要: A specific recording pattern is sequentially written onto an optical disc using each of three sets of recording pulse conditions as trial writing. The recording patterns are reproduced sequentially. Edge shift amounts of a mark which corresponds to each of three sets of recording pulse conditions are measured from a reproduction signal. Compensation values for the recording pulse conditions are obtained from calculation by linear approximation based on the measured values.

    摘要: In a disk camera, when additional information and moving picture information are managed as one file and recorded on an optical disk, useless area is minimized, thereby allowing effective use of recording capacity. A recording controlling part records continuously with respect to a logical block of the optical disk, at least one of input video and audio information in a packet format of a fixed length that is different from a data size of the logical block, and creates a data file for recording with respect to the logical block, additional information with respect to the video or audio information in the packet format of the fixed length. In this one data file, a fixed data size portion of the additional information is arranged in an area ahead of an area in which the video and audio information are arranged, and a variable data size portion of the additional information is arranged in an area behind the area in which the video and audio information are arranged.
