A recording medium, and a method and apparatus for reformatting the recording medium are disclosed. The method for reformatting a recording medium includes the steps of. (a) reading a plurality of physical access control information of the recording medium in a plurality of recording units; and (b) performing an initialization process for each recording unit upon receiving a reformatting command associated with the plurality of recording units, wherein the initialization process is differently performed according to an attribute of information recorded in each recording unit. Therefore, the PAC area contained in a high- density optical disc can be efficiently reformatted.
