The system plays the data stored in a plurality of disks driven by correspondent disk trays and disk drive mechanism in a single disk player by sharing a single disk servo mechanism, so that it can reduce the PCB occupancy space and the load to a microprocessor. The system comprises: 1st and 2nd gain variable adjustment units(13,17), connected to the disk drive mechanisms(11,15) and the disk trays(2,4) respectively, adjusting the optimal gain variables to operate the disk drive mechanisms(11,15) and the disk trays(2,4); a switching unit(19) sequentially performing switching operations according to alternately input switching signals; the disk servo mechanism(21) making the player read the data in the disk by driving the disk drive mechanisms(11,15); a standby servo mechanism(23) maintaining the wait state of the mechanisms(11,15).
