ABSTRACT:
In an information recording and reproducing apparatus for recording or reproducing information to/from tracks by irradiating a light spot to an optical disk in which N sectors are included per track and the number of necessary alternating sectors per track is set to M, the apparatus has a track format such that when a desired moving time of the light spot between the adjacent tracks is k times as long as a desired sector passing time of the light spot, M or more alterating sectors are arranged subsequent to the ordinary sectors to record user's data. The light spot jumps between the tracks for a period of time corresponding to k sectors. Thus, the recording of information to a certain track and the subsequent reading check (Read After Write) can be effectively executed at a high speed.
