ABSTRACT:
An optical information recording and reproducing apparatus includes a random information generating section for generating predetermined random information. A recording information generating section generates recording information on the basis of non-DC-free information and the predetermined random information. A synchronization sensing section senses a synchronization information. A recording section records the recording information in the recording area of a recording medium, on the basis of the synchronization information. A reproducing section reproduces the recording information recorded by the recording section.
