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.
