ABSTRACT:
A recording medium has a user-data zone in which a plurality of fragments can be reserved by recording the start and end addresses of the fragments, and a management information zone in which management information having recorded-area-indicator (RAI) information indicating whether each of partial areas into which the user-data zone is divided by a fixed size is a recorded area and fragment information concerning each fragment reserved in the user-data zone is recorded. RAI information and fragment information are acquired from the management information zone. A recording end position in the reserved fragment is searched for using the entirety of an area in a reserved fragment as a search range. A search range in an unreserved fragment whose end address is not defined is determined on the basis of the RAI information, and a recording end position in the unreserved fragment is searched for within the determined search range.
