ABSTRACT:
High speed access to an information recording medium is possible by preparing information relative to a lower level recording unit, e.g., a fragment, which is set smaller than a higher level recording unit, e.g., a session. A fragment identifier, typically, a fragment number is assigned to each fragment, sequentially and in ascending order. A fragment number (greatest fragment number) that is greater than any other fragment number in the session is recorded in the information recording medium for each session. When reproducing a desired fragment, a controller acquires the greatest fragment number of each session sequentially from the first session, and compares the greatest fragment number of the session with the fragment number of the desired fragment. When the greatest fragment number that is equal to or greater than the fragment number of the desired fragment is found, the desired fragment is searched for from the top of the session.
