Abstract

The present invention makes it possible to reproduce an optical disc in random reproduction or programmed reproduction without interrupting reproduction, even though discs such as a DVD or CD-I with an interactive function are not removed from the roulette. A mechanical unit 1 selects a target optical disc 103 to be reproduced from among a plurality of optical discs accommodated in a roulette 702. A disc detection unit 204 detects the type of the optical disc which is selected as the target to be reproduced. A system controller unit 5 allows reproduction only in a case where the target optical disc to be reproduced is a CD-DA, when the reproduction mode entered to the user interface block unit 6 is either a random-reproduction mode or a programmed-reproduction mode.
