PROBLEM TO BE SOLVED: To make it possible to speed up the announcement of the effect that an empty tray is erroneously selected by detecting the presence of a disk on a tray facing a recording and reproducing section, once storing the information on the presence or absence of the disk and actuating a tray drive mechanism upon detection that there is no disk on the tray from the information on the presence or absence of the disk in a memory when a manipulation signal is received. SOLUTION: When the tray 4 arrives at a position of EXTRA upon confirmation that the tray 4 arrives at the EXTRA position, i.e., that a switch SW2 is on and a switch SW3 is off, the lapse of the prescribed time is decided. When the time within the prescribed time is attained, a force OPEN operation is ended by deciding that the tray 4 can move smoothly between a HOME position and the EXTRA position. When the prescribed time elapses, the user's attention is aroused by judging that there is a hindrance in the forward and between movement of the tray 4. The number of repetition times of the retreat and advance of the tray 4 is then checked and the corresponding processing is executed by the number of the repetition times and the display to this effect is carried out.
