Abstract
An information recording medium includes a data storage section having a plurality of recording regions for storing data, and a region information storing section operable to store information about each recording region in the data storage section. The region information storing section stores information about a recording region (for example, a recording region has been accessed finally) which is set first as an accessible region when the information recording medium is initialized at the next time among a plurality of recording regions in the data storage section. A data processing apparatus refers to the information about the recording region and changes over a recording region to the recording region specified by the information about the recording region just after initialization of the recording medium.
