An optical disk apparatus is adapted to record into and reproduce information from a plurality of blocks on an optical disk medium (1). The respective block on the optical disk medium (1) has a preformat section which is continuously recorded with a plurality of ID information and a data recording section for recording information. The data recording section contains an information recording area, a recorded flag recording area and a post field. If the number of ID information detected never exceeds 2, then recording of the information into the corresponding block is inhibited, and the information is then recorded into a data alternative area instead. |
