More specifically, in the example described below, an optical disc, such as a so-called compact disc, in which a plurality of pieces of music information and catalog information serving as a list of a plurality of pieces of music information are recorded, for example, a music disc, An optical disc is used in which catalog information, which is a list of these plural pieces of music information, and a disc title, a player name, a composer name, a lyricist name, a title of each music information, and information on the genre of the song are recorded. . An optical disk having such a format is disclosed in Japanese Unexamined Patent Publication No. 9-73.
No. 54 is described.

As shown in FIG. 1, the first example of the recording medium reproducing apparatus according to the present invention includes a disk storage section 2 for storing a plurality of optical disks. The disc reproducing apparatus 1 selects one optical disc from a plurality of optical discs stored in a disc storage section 2, takes out the optical disc from the storage section 2, and reproduces the selected optical disc.

The disc reproducing apparatus 1 shown here rearranges the optical disc 200 in the disc storage section 2 based on the information on the optical disc 200 stored in the disc storage section 2. That is, information about the optical disc 200 has a relationship with another optical disc 200,
This indicates that there is a high possibility that the data will be reproduced continuously with the other optical discs 200. For example, the information on the optical disc 200 is information indicating a group that is reproduced continuously with another optical disc 200, for example, category information indicating a genre or a singer to which the optical disc 200 belongs.

The disc reproducing apparatus 1 has a disc storage section 2 having a plurality of slots for storing a plurality of optical discs 200, and a reproduction for reproducing information signals recorded on the plurality of optical discs 200 taken out of the disc storage section 2.

And a storage position storage area 5b for storing the storage position of the optical disk 200. In the disk input information storage area 5a of the RAM 5, the category information of the optical disk is stored at the address corresponding to the address given to each slot as each storage position of the storage unit 2. Generally, some commercially available optical disks do not record the above-described title, song name information, and genre information of the disk. In this case, the user operates an operation unit (not shown) to input necessary information and store it in the RAM 5. When category information such as a genre is recorded on the optical disc 200 in advance, the category information is read out by the reproducing unit 3 and stored in the storage area 5 a of the RAM 5.
Is written to.

The RAM 5 and the transport control circuit 6 are provided in a system controller 7. The system controller 7 controls, for example, the playback unit 3.

A plurality of slots are formed in the disk storage section 2 corresponding to storage positions for individually storing the plurality of optical disks 200, and the optical disks 200 are individually stored in these slots. Although not shown, the optical disc 20 is inserted into any of the slots in the disc storage unit 2.
A detection mechanism for detecting whether 0 is stored or not is provided, and the detection result by this detection mechanism is written to the storage position storage area 5b of the RAM 5 of the system controller 7.

The disk transport mechanism 4 transports the optical disk 200 between the storage section 2 and the playback position of the playback section 3. The disk transport mechanism 4 also performs an operation of taking out the optical disk 200 stored in the disk storage unit 2 and storing the optical disk 200 in another slot of the disk storage unit 2 according to a flowchart shown in the later-described figure.

The disc reproducing apparatus 1 having the above-described structure performs normal reproduction of the optical disc 200, and also controls the reproducing section 3 and the disc transport mechanism 4 by operating the operation switch of an operation section (not shown). Under the control, the plurality of optical discs 200 can be sequentially taken out of the storage section 2 and continuously reproduced by the reproducing section 3.

The disc reproducing apparatus 1 includes a disc storage unit 2
The optical disk 200 stored in the storage unit 2 is stored on the basis of the information on the optical disk 200 stored in the disk input information storage area 5a in the RAM 5 and the above-described category information.
Can be rearranged in the storage section 2. The information on the optical disk 200 stored in the disk input information storage area 5a is category information on the above-described genre, singer name, and the like of each optical disk 200 stored in the disk storage unit 2, for example.

The mode for performing the rearrangement of the optical disk 200 based on the information on the optical disk 200, that is, the category information, is executed in accordance with the flowchart shown in FIG. . For example, a case where the optical disc 200 is rearranged according to the category information will be described.

In the disk reproducing apparatus 1, first, as shown in step S 1, whether or not the user has operated the operation switch of the operation section (not shown) of the apparatus 1 to issue an instruction to execute the rearrangement of the optical disk 200 by the system controller 7 If it is confirmed in step S1 for performing the determination that the operation switch has been operated by the user and that a rearrangement execution command has been issued, the system controller 7 proceeds to step S2.
Proceed to. If no relocation execution instruction has been issued, the system controller 7 ends without executing the relocation mode.

In step S2, the system controller 7 searches for the category information of the first optical disk 200 stored in the disk input information storage area 5a of the RAM 5, and then, as shown in step 3, the disk storage unit 2 The first optical disc 200 stored in the
That is, it is determined whether or not the optical disk 200 stored at the address 1 of the storage unit 2 is stored in the RAM 5. In step S3, when the presence of the category information on the first optical disk 200 stored in the storage unit 2 is confirmed in the information stored in the disk input information storage area 5a of the RAM 5, as shown in step S4, The system controller 7 reads the category information from the disk input information storage area 5a of the RAM 5. The system controller 7 reads the category information from the RAM 5 and writes the category information in the memory area of the controller 7, and as shown in step S6, stores the category information read from the RAM 5 in the plurality of optical discs 200 stored in the disc storage unit 2. The last optical disk 2
00 is determined. Whether or not category information corresponding to the optical disc 200 is present in the disc input information storage area 5a of the RAM 5, that is, whether or not the category information is stored, corresponds to an address indicating a slot position as each storage position of the disk storage unit 2. The determination is made based on whether information is stored at the specified address.

On the other hand, if it is not determined in step S3 that the corresponding category information exists in the disk input information storage area 5a of the RAM 5, the system controller 7 is stored in the disk storage unit 2 in step S5. It is determined whether the optical disk 200 is the last optical disk 200, that is, the optical disk 200 stored at the last address of the disk storage unit 2.

If it is determined in step S5 that the optical disk 200 is not the last optical disk 200 stored in the disk storage unit 2, the system controller 7 proceeds to step S5.
As shown in FIG. 6, category information relating to the optical disk 200 stored in the disk input information storage area 5a of the RAM 5 is searched again.
It is determined whether or not the category information corresponds to the next optical disc 200 in the disc input information storage area 5a of AM5.

The system controller 7 determines in step S3
If it is confirmed in step S4 that the category information corresponding to the next optical disc 200 exists, the category information is stored in the disc input information storage area 5a of the RAM 5 in step S4.
Then, the data is read out and written into the memory area of the system controller 7, and subsequently, in step S5, it is determined whether the optical disk 200 is the last optical disk 200 stored in the disk storage unit 2. On the other hand, if the existence of the category information cannot be confirmed in step S3, the system controller 7
In step S5, it is confirmed whether the last optical disk 200 is stored in the disk storage unit.

The system controller 7 repeats the above-described operations from step S3 to step S6 for all the optical disks stored in the disk storage unit.
If it is determined in step S5 that the optical disk 200 is the last optical disk 200 stored in the disk storage unit 2, the process proceeds to step S7.

In step S7, the system controller 7 reads out from the disk input information storage area 5a of the RAM 5 and stores the category information stored in the memory area of the system controller 7 (not shown) in the system controller 7. The control unit determines the order in which the optical disks 200 are arranged. For example, the order in which the optical disks 200 having the same category information are arranged in the disk storage unit 2 is determined. After this determination, the system controller 7 controls the transport mechanism 4 by the transport control circuit 6 and rearranges each optical disc 200 in the determined order.

The system controller 7 determines in step S8
As shown in the figure, the first optical disk 200, for example, the optical disk 200 stored at the address 1 of the disk storage unit 2
Is taken out of the disk storage unit 2. As shown in step S9, the system controller 7 stores the removed optical discs 200 in the storage positions according to the determined order. However, in this case, an empty area, which is a slot where no optical disk is stored, is required in the disk storage unit 2.

After the operation in step S9 is completed, the system controller 7 determines whether or not the optical disk 200 rearranged in step S9 is the last optical disk 200 stored in the disk storage section 2, as shown in step S10. I do.

If it is determined in step S10 that the optical disk 200 is not the last optical disk 200 stored in the disk storage unit 2, the system controller 7 proceeds to step S11 to place the next optical disk 200 in the disk storage unit in the determined order. Remove from 2. The system controller 7 rearranges the next optical disk 200 taken out in a slot of the disk storage unit 2 adjacent to the optical disk 200 rearranged in the previous step S9 according to the determined order.

The system controller 7 repeats the rearrangement of the optical disc 200 as described above until it confirms that the rearranged optical disc 200 is the last optical disc 200 stored in the disc storage section 2 in step S10. Do.

As described above, the disc reproducing apparatus 1 performs the operation in the disc storage section 2 of the optical disc 200 by using the transport mechanism 4 based on the information on the optical disc 200, for example, the category information.
Swap the storage position of. Therefore, the disc reproducing device 1
Indicates that the disk storage 2
For example, optical disks of the same category can be arranged or stored in a nearby storage position.

In the disk reproducing apparatus 1 according to the present invention, when performing the above-described rearrangement mode and wishing to perform continuous reproduction for each category, the disk transport mechanism 4 promptly selects a desired optical disk 200 and sends it to the reproducing section 3. The optical disc 200 can be conveyed, and the time for taking out, storing, and conveying the optical disc 200 from the disc storage section 2 when continuous reproduction based on the category is performed can be shortened. Further, the disc reproducing apparatus 1 can minimize the operations of taking out, storing, and conveying the optical disc 200 by the disc transport mechanism 4, and thus can reduce power consumption during continuous reproduction. The drive noise of the disk transport mechanism 4 due to the transport operation of the optical disk 200 can be reduced by minimizing the operation of taking out, storing, and transporting the optical disk 200 by the transport mechanism 4. Furthermore, since the optical disc 200 is stored in the disc reproducing apparatus 1 for each category, the user can control the optical disc 2
00 can be easily managed. Therefore, the user does not need to perform a troublesome operation such as finding a storage position so as to be classified by category.

The disk reproducing apparatus 1 according to the present invention can also execute the above-described optical disk relocation operation using a timer at a predetermined time or a non-use time. For example, if the optical disk relocation mode is executed during a time period when the disk reproducing device 1 is not operated, for example, at midnight, the optical disk 200 can be relocated by category, for example, by genre in the next morning. Thus, the use efficiency of the optical disc reproducing apparatus 1 is improved.

Next, the second embodiment of the disk reproducing apparatus according to the present invention will be described.
Will be described.

The disc reproducing apparatus according to the second embodiment of the present invention has the same basic configuration as that of the first embodiment shown in FIG. 1 described above, and is described with reference to FIG. About a structure, detailed description about FIG. 1 is cited and detailed description is abbreviate | omitted.

The disc reproducing apparatus 1 according to the second embodiment of the present invention, after the end of the reproduction,
0, for example, an optical disc 200 that has been reproduced based on category information such as a genre and a singer's name.
0 is stored in a slot where the optical disk 200 is not stored in the storage area of the disk storage section 2 in which the optical disk 200 is stored, that is, in an empty area.

The disc reproducing apparatus 1 of the second example checks whether or not the information on the optical disc 200 reproduced by the reproducing section 3 is stored in the disk input information storage area 5a of the RAM 5. After confirming the information, the disc reproducing apparatus 1 reads the disc 2
The optical disk 200 whose reproduction has been completed is stored in the slot as the storage position where the optical disk 200 having the same category information as 00 is stored. The confirmation of the empty storage position is performed based on the information stored in the storage position storage area 5b in the RAM 5.

The storage mode immediately after the reproduction of the optical disc 200 is completed based on the information on the optical disc 200 is executed according to the flowchart shown in FIG. In the following, a case where the optical disc 200 is stored according to, for example, category information will be described.

In the disk reproducing apparatus 1, the system controller 7 determines whether or not the reproduction of the optical disk 200 has been completed as shown in step S21, and when it is confirmed that the reproduction has been completed, the process proceeds to step S22. If the reproduction of the optical disc 200 is not completed in step S21, the optical disc 200 is in a standby state until the reproduction is completed. The determination as to whether or not the reproduction of the optical disk 200 by the reproduction unit 3 is completed is performed by, for example, recording the time code or address information read from the optical disk 200 together with the music information based on the catalog information recorded on the optical disk 200. This is performed by determining whether or not the last time code or the last address has been reached.

In step S22, the system controller 7 determines whether or not there is category information corresponding to the optical disc 200 whose reproduction has been completed. The determination of the presence or absence of the category information is performed based on whether or not the category information of the optical disk 200 is stored in the disk input information storage area 5a of the RAM 5 in which the category information of the optical disk 200 is stored as in the first example.

Disk input information storage area 5a of RAM 5
If the presence of the category information corresponding to the optical disc 200 whose reproduction has been completed can be confirmed in step S23, as shown in step S23, the system controller 7 stores the same category information in the disc storage unit 2 as the optical disc 200 whose reproduction has been completed. A search is made for an empty storage position of the area in which the optical disk 200 is stored based on the information in the disk input information storage area 5a of the RAM 5, and then, in step S24.
As shown in (1), it is determined whether there is an empty storage position in the corresponding storage area. The determination of the presence or absence of an empty storage position in the storage area is performed by storing the storage position storage area 5 in the RAM 5.
b, the optical disk 2 is detected by the detection mechanism (not shown)
This is performed by searching for data indicating that 00 is not stored, or whether there is a position or slot where a flag indicating that the optical disk 200 is stored is not set. If it is possible to confirm that there is an empty storage position in the storage area searched, step S
As shown in FIG. 25, the system controller 7 controls the optical disc 200 taken out of the reproducing unit 3 by the transport mechanism 4.
Is stored in an empty storage position of the disk storage unit 2 and returned.

The optical disk 2 having the same category information as the optical disk 200 whose reproduction has been completed in step S24
If it is confirmed that there is no empty storage position in the area where 00 is stored, as shown in step S26, the system controller 7 moves the optical disc 200 after the reproduction to the empty storage position near the area. To store.

On the other hand, if it is determined in step S22 that the category information corresponding to the optical disk 200 whose reproduction has been completed cannot be confirmed in the disk input information storage area 5a in the RAM 5, the system controller 7 proceeds to step S27. As shown in the figure, the optical disk 200 after the reproduction is stored from the disk storage unit 2 in the original storage position where the optical disk 200 whose reproduction has been completed was originally stored. Similarly, when there is no slot as an empty storage position in the disk storage unit 2, that is, when the optical disk 200 is fully stored in the disk storage unit 2, the optical disk 20 is stored in the disk storage unit 2.
Optical disk 2 whose reproduction has been completed at the original position from which 0 was taken out
Store and return 00.

The disc reproducing apparatus 1 according to the second embodiment of the present invention stores the optical disc 200 after reproduction in the disc storage section 2 in the storage mode based on the information on the optical disc 200, for example, the category information as described above. I do. The disc reproducing apparatus 1 can store the reproduced optical disc 200 side by side with the optical disc 200 having information of the same category, for example.

Therefore, the disc reproducing apparatus 1 of the second example performs the operation of storing the optical discs whose reproduction has been completed based on the flowchart as shown in FIG. In the case of reproduction, the disc transport mechanism 4 can quickly take out the desired optical disc 200 from the disc storage section 2 and transport it to the reproduction section 3, and the disc storage section of the optical disc 200 in the case of continuous reproduction based on the category. 2, the time for taking out, storing, and transporting can be shortened.

Further, the disc reproducing apparatus 1 according to the second embodiment of the present invention can minimize the selection and transport operations of the optical disc 200 by the disc transport mechanism 4, thereby reducing power consumption during continuous reproduction. Can be reduced. By minimizing the time for storing, taking out, and transporting the optical disc, the noise of the disc transport mechanism 4 due to the transport operation of the optical disc 200 can be reduced.

Since a plurality of optical discs 200 are stored in the disc storage section 2 by category, for example, the user can easily manage the optical discs 200.
When storing the optical disk in the disk storage unit 2, it is not necessary to perform a troublesome operation such as finding a storage position so as to be classified by category.

Next, the third embodiment of the disk reproducing apparatus according to the present invention will be described.
Will be described. This disc reproducing apparatus 100 is similar to that shown in FIG.
As shown in FIG. 2, one optical disk 200 is taken out from the disk storage unit 2 for storing a plurality of optical disks 200 and is reproduced by the reproducing unit 3 based on the reproduction history information of the optical disk 200 reproduced in the past. The obtained relocation information is generated, and the plurality of optical discs 200 stored in the disc storage unit 2 are generated based on the generated relocation information.

And a transport control circuit 6 for rearranging the optical disc 200. here,
As will be described later, the reproduction history information is, for example, information including the address information of the storage position of the disk storage unit 2 in which the optical disk 200 reproduced by the reproduction unit 3 is stored, the date of reproduction, and the like.

The RAM 5 has a storage position storage area 5b for storing the storage position of the optical disk 200, as in the first example described above.

The rearrangement mode of the optical disc 200 performed based on the reproduction history information of the optical disc 200 is executed by the system controller 77 according to the flowchart shown in FIG.

In the disk reproducing apparatus 100 according to the third embodiment of the present invention, first, as shown in step S31, the operation switch of the operation unit (not shown) provided in the disk reproducing apparatus 100 is operated by the system controller 77, and the operation is restarted. It is determined whether a placement execution instruction has been input. here,
If it is confirmed that there is a relocation execution instruction, the system controller 77 proceeds to step S32. If the execution instruction of the rearrangement has not been issued by the switch S31, the system controller 77 ends without executing the rearrangement mode.

In step S32, the system controller 77 reads the reproduction history information on the optical disc 200 stored in the reproduction history storage information area 5c of the RAM 5. After reading the reproduction history information from the reproduction history storage information area 5c of the RAM 5, the system controller 7

A weighting coefficient corresponding to the reproduction frequency is calculated for the interrelationship between them. The calculation of the weighting coefficient is performed in the reproduction history storage area 5.
This is performed by the statistical processing circuit 8 on the basis of the reproduction history information of the optical disk stored in c. The weighting factor is
As described above, the value indicating the relevance to another optical disc 200 is calculated so as to increase the value between other optical discs that are frequently reproduced continuously.

After calculating the weighting factors, the system controller 77 operates the disk transport mechanism 4 by the transport control circuit 6 according to the relocation information including the calculated weighting factors, as shown in step S34, and The optical disk 200 is removed from the slot and replaced with another optical disk 200, thereby rearranging the optical disk 200 and terminating the rearrangement mode. By this rearrangement, the optical disc 200 is stored from the first storage position of the disk storage unit 2, for example, in the descending order of the weighting coefficient, that is, the frequency of the continuous reproduction.

As described above, the disc reproducing apparatus 100 of the third example uses the rearrangement mode based on the reproduction history information of the optical disc 200 to operate the disc storage sections of the plurality of optical discs 200 already stored in the disc storage section 2. 2, the optical discs 200 are rearranged, for example, in the descending order of reproduction frequency.

Therefore, the disk reproducing apparatus 100 according to the third embodiment of the present invention is in a state where the optical disk 200 having a high reproduction frequency is stored in the disk storage section 2 after execution of the rearrangement mode. 4 can quickly take out the desired optical disk 200 from the disk storage unit and transport it to the reproducing unit 3. The disc reproducing apparatus 100 can minimize the operation time for taking out, storing, and transporting the optical disc 200 from the disc storage unit by the disc transport mechanism 4, thereby reducing power consumption during continuous reproduction. Optical disk 200
The drive noise of the disk transport mechanism 4 due to the transport operation described above can be suppressed.

The disc reproducing apparatus 100 according to the third embodiment of the present invention can execute the relocation mode of the optical disc at a predetermined time or at a non-use time of the apparatus. It can also be executed automatically and periodically. For example, if the optical disc relocation mode is executed during a time period during which the disc reproducing apparatus 100 is not operated, for example, at midnight, the optical discs 200 stored in the disc storage unit 2 are sorted in the order of high reproduction frequency the next morning. The optical disc reproducing apparatus 10 can be rearranged.
0 can be used more efficiently.

FIG. 6 shows a more specific example of the flowchart shown in FIG. 5 described above. According to the flowchart shown in FIG. 6, a weighting coefficient based on the reproduction history information is determined by the statistical processing calculation circuit 8, and the transport mechanism 4 is controlled by the transport control circuit 6 of the system controller 77 to execute the rearrangement mode.

First, First, as shown in step S41, the system controller 77
It is determined whether or not the operation switch of the operation unit (not shown) of 00 is operated to issue a rearrangement execution instruction. Switch S
If it is confirmed at 41 that there is a relocation execution instruction,
The system controller 77 proceeds to step S42.
If a relocation execution instruction has not been issued by the switch S41, the system controller 77 ends this processing without executing the relocation mode.

In step S42, the system controller 77 sets the reproduction history storage information area 5c in the RAM 5
The reproduction history information on the optical disk 200 stored in the storage device is read. Reproduction history storage information area 5c in RAM 5
If no reproduction history information on the optical disk 200 to be read is stored in the first optical disk 200, the latest reproduction history information on the next optical disk 200 is read.

After reading the latest reproduction history information from the RAM 5, the system controller 77 proceeds to step S43.
As shown in the figure, the reproduction history storage information area 5c in the RAM 5
It is determined whether or not the readout history information of the optical disc 200 which has been read before exists. Here, the previous playback history information is
This is old playback history information before that in time.

When it is confirmed that the read reproduction history information of the optical disk 200 exists before, the statistical processing calculation circuit 8 of the system controller 77 proceeds to step S4.
As shown in FIG. 4, an initial value α is given to the weighting coefficient s, and then, as shown in step S45, an addition value β is added to the weighting coefficient s. For example, the initial value α = 1 and the added value β =
The weighting coefficient s is calculated by adding 0.5.

After calculating the weighting coefficient s, the system controller 77 sets the RA as shown in step S46.
The reproduction of the same optical disc 200 that is earlier in time than the previous reproduction history information as to whether the previous reproduction history information read out into the reproduction history storage information area 5c of M5 is the last, that is, the oldest reproduction history information. Determine whether there is history information.

In step S 46, the reproduction history information before read from the RAM 5 is stored in the reproduction history storage information area 5 c in the RAM 5.
If it is not the last reproduction history information relating to 00, the system controller 77 subtracts the added value β as shown in step S47, and again adds the correlation coefficient β to the weighting coefficient s in step S45. In step S47, for example, the correlation coefficient β is reduced from 0.5 to 0.25, and in step S45, the weighting coefficient s is 1.7.
It becomes 5.

On the other hand, in step S46, the RAM 5
The reproduction history information before read out from the optical disc 2 is stored in the reproduction history storage information area 5c of the RAM 5.
If it is determined that the information is the last reproduction history information relating to 00, the system controller 77 proceeds to step S49. In step S43, if the same reproduction history information for the optical disc 200 cannot be confirmed in the reproduction history storage information area 5c of the RAM 5 before, as shown in step S48, the initial value α is set as the weighting coefficient s.
, And the process proceeds to step S48. Here, the initial value α
Is the same value as the initial value given in step S44,
For example, it is set to 1.

In step S 49, the system controller 77 determines whether or not the playback history information is for the last optical disk 200 stored in the disk storage unit 2.

Here, a description will be given of a case where a weighting coefficient of each reproduced optical disk as shown in Table 1 is calculated. The calculation of the weighting coefficient s is performed for each optical disc 200 for continuous playback within the same day and continuous playback within a certain period.

[0076]

[Table 1]

For example, since the optical disks D ₁ and D ₂ are reproduced on February 1, the weighting coefficient s
Is given as an initial value α = 1. Further, since the reproduction history information in which the optical disks D ₁ and D ₂ are continuously reproduced exists before, that is, also on January 29, the added value β = 0.5 is added and the weighting is performed. Coefficient s
Is calculated. That is, the weighting coefficient s becomes 1.5. If the reproduction history information of the continuous reproduction of the optical disc D ₁ and the optical disc D ₂ also exists before, that is, it also exists on January 28, the subtracted addition value β = 0.
A weighting coefficient s to which 25 has been added is calculated. Thus, the weighting coefficient s between the optical discs D ₁ and D ₂ is calculated as 1.75 as shown in Table 2.

[0078]

[Table 2]

Similarly, a weighting coefficient between the respective optical disks D ₁ , D ₂ , D ₃ , D ₄ and D ₅ is obtained as shown in Table 2 based on the reproduction history information of Table 1. Can be

The system controller 77 determines in step S
In 49, if it is determined that the reproduction history information is for the last optical disc 200 stored in the disc storage unit 2, the information is organized based on the weighting coefficient α obtained for each optical disc 200 as shown in step S50. And obtains relocation information.

The system controller 77 rearranges the optical disk 200 based on the rearrangement information generated based on the weighting coefficients obtained as described above. That is,
The system controller 77 takes out the first optical disk 200 from the disk storage unit 2 by the transport mechanism 4 as shown in step S51, and as a storage position of the disk storage unit 2 based on the relocation information as shown in step S52. The optical disk 200 taken out is stored. After storing the optical disk 200, the system controller 77 determines whether the stored optical disk 200 is the last optical disk 200 stored in the disk storage unit 2 as shown in step S53. If it is determined in step S53 that there is the last optical disk 200 stored in the disk storage unit 2, the process is terminated.

In step S53, the last optical disk 200
If not, the system controller 77 takes out the next optical disk 200 from the slot as the storage position of the disk storage unit 2 based on the relocation information as shown in step S54, and as shown in step S52, The next optical disc 20 is stored at the storage position based on the relocation information.
0 is stored.

In the above-described rearrangement of the optical disk 200, the system controller 7 determines that the optical disk 200 is the last optical disk 200 stored in the disk storage section 2 in step S53.
