A barrier mechanism, which is often utilized in a disk changer device, is disclosed herein, in which the barrier mechanism includes two wheels and a barrier belt loop. The two wheels are respectively installed on a top terminal and a bottom terminal of an edge of the disk insertion opening of the magazine. A barrier belt loop which is used for selectively traverse one of the plurality of disk holding members, includes an inner section with a traversing recess carved therein. The inner section is adjacent to the disk insertion opening of the magazine of the disk changer device, and the mechanical coupling between the barrier belt loop and the processing mechanism enables the traversing recess constantly aligned with the optical pick-up unit. Accordingly, the traversing recess is horizontally aligned with the predetermined disk holding member, thereby the procedure enables the drafting unit to extract the predetermined disk holding member through the traversing recess into the optical pick-up unit.
