Described is a read and/or record device for discs, the device including a housing (2), at least one disc magazine (4) with a multiplicity of superposed disc holders (5) mounted in compartments and each designed to hold one disc, at least one disc drive (3) enabling data to be read off or recorded on the disc, a disc-conveying device (6) designed to move past the stack of compartments in the magazine (4) and to convey the required disc, together with its holder (5), back and forth between the magazine (4) and the disc drive, and a central control unit. In order to prevent a disc holder (5) without a disc being conveyed to the disc drive (3), while at the same time ensuring a high level of reliability, the disc-conveying device (6) operates in conjunction with a detector unit (9) fitted to the housing and designed to detect the presence of a disc in the disc holder (5) carried by the conveying device (6).
