ABSTRACT:
In a rewritable recording medium, in which the opposite track path is adopted, having a plurality of recording layers, the confirmation of the formation of a middle area is made to be faster and easier. Within a predetermined management information area (e.g., lead-in) of a disc, intermediate-area management information (middle status) indicating whether or not a guard intermediate area (middle area) whose one end is the inter-layer transition position (inter-layer loopback address) which is determined according to the recording of user data is recorded. As a result, it is possible for a recording and reproduction apparatus to determine whether or not the middle area needs to be formed on the basis of the value of the intermediate-area management information.
