A disc seating tray of an optical disc recording / reproducing apparatus, which can prevent the detachment of a disc.

In general, an optical disc D used in a recording / reproducing apparatus such as a digital versatile disc (DVD) is a type of recording medium for recording information in a spiral or concentric track or for reproducing the recorded information. The conventional tray for seating such an optical disk into the optical disk recording and reproducing apparatus is provided with a tray 12 which is taken out and / or inserted into the case 10, as shown in FIGS. In the upper surface of the tray 12, a mounting groove 12a is formed to seat the optical disk, and an opening 12b is formed on the bottom surface of the tray 12 to expose the non-magnetic and magnetic portions of the optical disk to the outside.

Inside the case 10, a deck base 16 having a turntable 14 is installed to be in contact with the bottom surface of the non-magnetic portion of the optical disk while being raised at a predetermined angle by a loading mechanism (not shown). An optical pickup device (not shown) is provided for storing or reproducing the stored record on the surface of the optical disc while being transferred in the radial direction of the optical disc.

In the conventional tray configured as described above, when the ejecting button (not shown) provided on the front of the case 10 is pressed in order to record and / or reproduce information on the recording surface of the optical disk, the tray 12 is rotated by the rotation of the drive mechanism. Is taken out while horizontally moving forward of the case 10, and the optical disc having a diameter of 12 cm is seated on the taken out tray 12. At this time, the optical disk is seated in the mounting groove 12a formed in the tray 12 to prevent the microfluidic flow and at the same time the magnetic portion is exposed to the opening 12b.

Then, when the ejecting button is pressed again, the driving mechanism is rotated to draw the tray 12 into the case 10, and when the drawing is completed, the loading mechanism installed inside the case 10, that is, the nonmagnetic portion of the optical disk, is pressed. The information is recorded and / or reproduced on the optical disc by the deck base 16 having the turntable 14 and the optical pickup device which is linearly reciprocated so that the contact is in close contact with each other.

However, although the optical disc is placed on the tray to be taken out and / or drawn while moving horizontally with respect to the horizontally installed case as described above, the recording stored therein is reproduced, but the tray is applied to the vertically standing case. In this case, there is a disadvantage in that the optical disk seated on the tray is separated during the horizontal movement of the tray.

In addition, a separate locking means is not provided to prevent separation of the optical disc, so that the tray can not be used in both the horizontal and vertical optical disc recording and reproducing apparatuses, thereby decreasing compatibility, and particularly suitable for the horizontal and / or vertical type. Since the tray must be provided separately, there was a problem that the economic cost is increased.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to prevent the detachment of an optical disk seated on a tray when the optical disk recording and reproducing apparatus is used vertically, as well as horizontal and / or vertical type. The present invention provides a disc seating tray of an optical disc recording / reproducing apparatus that can use a single tray for the recording / reproducing apparatus not only to improve compatibility, but also to reduce economic costs.
