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.
Claims4
An optical disc reproducing apparatus capable of accommodating a plurality of different kinds of optical discs, comprising:
- disc detection means for detecting the kind of optical disc;
- disc selection means for selecting an optical disc to be reproduced from among the accommodated optical discs;
- and
- mode receiving means for receiving a reproduction instruction, including at least one of a random-reproduction mode for continuously reproducing the accommodated optical discs at random and a programmed-reproduction mode for selectively reproducing the accommodated optical discs in a predetermined order, wherein:
- said disc selection means only selects optical discs from among the accommodated optical discs which is detected by said disc detection means to be a CD-DA (Compact Disc-Digital Audio), when a reproduction instruction in said random-reproduction mode or programmed-reproduction mode is received by said mode receiving means.
An optical disc reproducing apparatus capable of accommodating a plurality of different kinds of optical discs, comprising:
- disc detection means for detecting whether an optical disc has any interactive program tracks;
- disc selection means for selecting an optical disc to be reproduced from among the accommodated optical discs;
- and
- mode receiving means for receiving a reproduction instruction, including at least one of a random-reproduction mode for continuously reproducing the accommodated optical discs at random and a programmed-reproduction mode for selectively reproducing the accommodated optical discs in a predetermined order, wherein:
- said disc selection means only selects optical discs from among the accommodated optical discs which is detected by said disc detection means to have no interactive program tracks, when a reproduction instruction in said random-reproduction mode or said programmed-reproduction mode is received by said mode receiving means.
