Abstract
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 is preliminarily stored on a buffer memory, and during a period in which the optical pickup is shifted to another information track, the recording information, stored in the buffer memory, is reproduced; and upon recording, during a period in which the optical pickup is shifted to another information track, recording information is temporarily stored in the buffer memory, and after completion of the recording, the recording information is recorded on the optical disk. 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.
