Abstract
Abstract An information recording medium, such as an optical card, has a plurality of sectors of different sizes. First, an optical head records information in those of the sectors which have a predetermined size on the information recording medium. Then, the optical head reproduces information recorded in the sectors having the predetermined size on the recording medium. Then, the optical head records the information, reproduced from those sectors having the predetermined size, in another sector or other sectors among the plurality of sectors on the recording medium, which have a relatively larger size than the predetermined size. Only the information of a desired portion may be extracted at the time of reproduction, and recorded in another sector or sectors at the time of re-recording.
