The invention relates to a disc magazine (1) to be inserted in the housing (6) of disc changers, disc players, computers or the like, comprising a housing mounting frame (2) in which multiple disc holders (9) lying on top of each other are placed in mounting compartments (11), each plate holder accommodating one disc, and a cover (3) which is connected to the mounting frame (2). In order to automatically protect the disc holder (9) placed therein from falling off or damaging when the disc magazine (1) is taken out from a corresponding device, the cover (3) comprises a flexibly mounted locking element (19) which engages in corresponding recesses in the disc holder (9) and which releases the disc holder (9) when the disc magazine (1) is slid into the mounting frame (6).
