When the piece 232a abuts, the movement of the piece 232a is blocked and the piece 232a cannot be moved.
That is, the eject operation is prevented in the recording mode of the optical disk recording apparatus.

When the recording mode of this optical disk recording apparatus is released by operating a stop operation button or the like (not shown), recording of the information signal in the first recording area of the optical disk 101 ends, and Recording of the catalog information is started in the second recording area in which the catalog information is recorded other than the area in which the signal is recorded. While the catalog information is being recorded, the eject prevention lever 215 and the magnetic head device 212 are kept in the recording mode described above with reference to FIGS. 14 and 15. Therefore, in this optical disc recording apparatus, even while the catalog information is being recorded,
Eject operation is restricted.

When the recording of the catalog information is completed, the control means releases the attraction of the suction coils 216, 253 to the eject blocking lever 215 and the attracted piece 252. Then, the ejection blocking lever 215 is returned to the initial position by the biasing force of the tension coil spring 243 as shown in FIG. Therefore, at this time, if the pressing operation portion 234 is pressed, the eject plate 232 inserts the contact protruding piece 232a between the pressed operation piece 215c and the ejection blocking piece 215d, and in the direction of arrow h in FIG. Is moved to the rear side of. This eject plate 232
The eject operation is performed by moving the to the rear side. That is, in this optical disc recording apparatus, when the recording of the catalog information on the optical disc 101 is completed, the eject operation becomes possible.
