ABSTRACT:
A battery-operated recording medium controller monitors the ID of a replayed melody and when a replay ID comparing section (A126) makes a decision that a melody of the same ID as the previous one is replayed, a section (A127) for judging necessity of auxiliary information designates an auxiliary information access control section not to acquire auxiliary information (ID3 tag) again from a disc but to reuse auxiliary information stored in an auxiliary information storing section A. Consequently, the number of times of accessing the recording medium is decreased, and when the auxiliary information added to reproduction data like the ID3 tag of an MP3 is acquired, moving distance of an optical pickup is decreased and current consumption can be reduced.
