摘要： A reproducing light quantity control method for an optical memory device includes the steps of (1) recording test data on an optical recording medium; (2) reproducing the test data recorded on the optical recording medium by changing a reproducing light quantity in a plurality of light quantity values; (3) measuring a quality value and a signal quantity of each of a plurality of reproducing signals from the test data; (4) selecting an optimum reproducing signal quantity from a plurality of reproducing signal quantities in accordance with quality values of the plurality of reproducing signals so as to decide a target value of reproducing signal quantity; and (5) recording the target value on a target value recording region of the optical recording medium. This method reduces the time required to obtain a target value of a reproducing signal quantity and speeds up an operation from installing of the optical recording medium to finishing of preparation for recording and reproducing.

摘要： An information recording-reproduction method wherein: upon reproducing, recorded information corresponding to a predetermined number of sectors from the leading sector of each of a plurality of information tracks on an optical disk (1) is preliminarily stored on a buffer memory (19), and during a period in which the optical pickup (3) is shifted to another information track, the recording information, stored in the buffer memory (19), is reproduced; and upon recording, during a period in which the optical pickup (3) is shifted to another information track, recording information is temporarily stored in the buffer memory (19), and after completion of the recording, the recording information is recorded on the optical disk (1). In this method, information tracks, which are formed on the optical disk discontinuously with one another, are regarded as if they were continuous tracks, and the apparent recording and reproducing operation is carried out continuously.
