The inspection is performed one after another while sequentially exchanging the disks until the inspection of the disks is completed, and when the inspection of the set number of disks is completed, the inspection operation is completed. As a result, it becomes possible to continuously and automatically inspect an arbitrary set number of discs.

〔Example〕

An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 shows an embodiment of an automatic loading disc type recording medium inspection apparatus according to the present invention. This inspection device 1
Checks various characteristics of the optical disc.

The inspection device 1 is provided with an optical disc stacker 2 for accommodating a plurality of (for example, 16) optical discs. Further, an optical disk drive unit 3 for rotating and driving the optical disk to write signals to and read recorded contents from the optical disk, and an inspection control unit 4 are provided. As shown in FIG. 2, the inspection control unit 4 performs various inspections on the optical disc (detection of defects with variable read signal slice level, measurement of recording sensitivity with variable write signal level, etc.). The control signal is supplied to the drive unit 3 and the read signal of the drive unit 3 is input to play a role of obtaining information regarding the quality of the disk to be inspected based on the read signal. This information obtained by the inspection control unit 4 is
If necessary, it is provided to a host system (not shown).

The transfer of the optical disc between the stacker 2 and the drive unit 3 is performed by the automatic loading mechanism unit 5 and the automatic loading control unit 6. The automatic loading mechanism unit 5 includes a ball screw 7 rotatably supported in the apparatus 1 in a vertical direction (direction of arrow Y in the figure), a drive motor 8 for rotating the screw 7, and a screw 7 for rotating the screw 7. And an optical disk carrier 9 that moves in the vertical direction according to the rotation. The carrier 9 moves the optical disk in the horizontal direction (the direction of arrow X in the figure) to remove the optical disk from the stacker 2 and the drive unit 3.
Also, the optical discs are stored and mounted in the stacker 2 and the drive unit 3. The automatic loading control unit 6 plays a role of controlling each operation of the automatic loading mechanism unit 5 as shown in FIG.

The operation monitor display unit 10 is for setting inspection conditions (inspection items, the number of optical disks to be inspected, etc.) when performing inspection. A signal indicating the set conditions is given to the inspection control unit 4 and the automatic loading control unit 6. Further, on the operation monitor display unit 10, signals indicating the inspection status at the time of inspection and the operation status of each unit are displayed.
These contents are displayed.

An example of the inspection operation of the optical disc by the inspection device 1 is as follows.

When the operator sets the inspection conditions on the operation monitor display unit 10, the automatic loading mechanism unit 5 starts to operate under the control of the automatic loading control unit 6, and any one of the plurality of optical disks 11 stored in the stacker 2 is started. After the optical disk 11 (for example, the optical disk 11 stored in the uppermost stage) is taken out by the carrier 9,
The motor 8 rotates to move the carrier 9 to the position of the height of the drive unit 3, and the carrier 9 inserts the disk 11 into the drive unit 3. The drive unit 3 writes signals to and reads recorded contents from the disc 11 under the control of the inspection control unit 4, and the inspection control unit 4 determines the quality of the disc 11 based on the read signal from the drive unit 3. Information regarding the track is obtained for each track and each sector.

When the inspection of the disk 11 is completed, the automatic loading mechanism section 5 starts to operate again, and the carrier machine 9 takes out the disk 11 inserted in the drive section 3 and then the motor 8 rotates to rotate the disk 11. The carrier 9 is moved to the position where it was initially stored (the uppermost stage of the stacker 2 in the above example), and the carrier 9 stores the disk 11 in the stacker 2. Then, the motor 8 is rotated again and the carrier 9
Is moved to the position of the height of another disc 11 (for example, the disc 11 stored in the second stage from the top), this time another disc 11 is taken out by the carrier 9 and the same as the above. Various transfer and inspection processes are performed on the other disk 11.

In this manner, a plurality of optical discs to be inspected are automatically exchanged, and the discs are inspected one by one while the last disc is inspected. Store in the storage position and complete all operations.

〔The invention's effect〕

As described above, according to the automatic loading type disc type recording medium inspection apparatus of the present invention, the operation of inserting the disc type recording medium to be inspected into the disc driving means and the disc driving means of the disc type recording medium which has been inspected from the disc driving means are checked. Removal work can be performed automatically without operator intervention.
Therefore, even in the field of optical discs where these operations have been performed manually, it is possible to always perform efficient inspection without lowering work efficiency regardless of the number of discs to be inspected.

Moreover, the inspection is performed one after another while sequentially replacing the disks until the inspection of the set number of disks is completed, and the inspection operation is terminated when the inspection of the set number of disks is completed. This has an excellent effect that the set number of disks can be continuously and automatically inspected.
