2. Description of the Related Art Conventionally, as a CD player for reproducing a CD, a CD player equipped with a disc changer device is known. Basically, the disc changer device includes a storage unit for storing a plurality of CDs, and a loading mechanism for loading a CD arbitrarily selected from the plurality of CDs into a reproduction unit of a CD player. A disk changer device using a rotary stocker as a storage unit is known. This rotary stocker has a plurality of grooves extending radially from the rotation shaft, and a CD is placed in these grooves in a standing state. A CD player equipped with a disc changer device has a reproducing unit for reproducing recorded contents of a CD. The playback unit is
The system includes a turntable for holding a disk, a rotation mechanism for rotating the turntable, an optical pickup for reading contents recorded on a CD, and a moving mechanism for moving the optical pickup in a radial direction of the CD. This reproduction unit is provided adjacent to the rotary stocker so that the rotation axis of the turntable is horizontal.

In the CD player having the above configuration, one of the plurality of disks is moved to a position corresponding to the reproducing unit by rotating the rotary stocker. Then, the loading mechanism loads the one disk into the reproducing unit. Then, one side of the CD is reproduced by the reproduction unit.

Things that did not exist. " According to the present invention, when the loaded disc is read and the reading is completed, the disc can be turned over and automatically loaded to the reading means. Accordingly, even when a user or the like stores a disk having information recorded on both sides (hereinafter, referred to as a double-sided disk) in the storage means, both sides of the disk can be reproduced. On the other hand, in the present invention, when the reading means cannot read the disc, the disc can be turned over and automatically loaded on the reading means. Therefore, according to the present invention, it is possible to reproduce even a disk such as a CD or DVD on which information is recorded on only one side (hereinafter, referred to as a single-sided disk). Therefore, the user can store the single-sided disc in the storage means without worrying about the front and back. That is, the user does not need to take out the disk stored upside down once.

According to a second aspect of the present invention, in the disk device according to the first aspect, first means for operating the reversing means when the reading means cannot read the disk loaded by the loading means (for example, FIG. 3 and the CPU 20 shown in FIG. 4: step S8) is characterized in that the control means has the above.

As described above, according to the second aspect of the present invention, when the reading means cannot read the loaded disc, the reversing means operates, so that the single-sided disc is stored upside down in the storing means.

As described above, according to the third aspect of the invention, the same operation and effect as those of the second aspect of the invention can be obtained, and when the reading means cannot read the disc which has been reversed and loaded. The disk is transported to the storage means. Therefore, a disc on which information is not recorded on both sides or a disc whose information is broken on both sides and which is loaded on the reading means automatically returns to the storage means. Therefore, even when a user or the like stores a disc on which both sides are not recorded in the storage means, the state in which the disc is loaded on the reading means is not maintained.

According to a fourth aspect of the present invention, a storage means capable of storing a plurality of disks and a first reading means for reading one surface of the disks (for example, the optical pickup 11 of the first reproducing unit 2 shown in FIG. 11) And second reading means (for example, the optical pickup 11 of the second reproducing unit 2 shown in FIG. 11) for reading the other surface of the disc, and one disc stored in the storing means, And a loading device (for example, a first loading mechanism 6 shown in FIG. 11) for loading the second reading device, wherein a disk loaded on one of the first reading device and the second reading device is loaded. An exchange means (for example, a disc changer device 3 shown in FIG. 11) for loading the other, and a disc loaded on the one side. A control means for controlling the fill switch means based on a result of one above read (e.g., FIG. 12
And a control device 4) shown in FIG.

As described above, according to the present invention, the loading means loads one of the plurality of disks stored in the storage means to one of the first reading means and the second reading means. . Then, one of the reading means tries to read the loaded disk, but since the replacement means is controlled based on the result of reading the disk, the disk loaded on one of the reading means is automatically read by the other. Loaded by means. Here, the first reading unit reads one surface of the disk, and the second reading unit reads the other surface. Therefore, the disc loaded from one reading unit to the other reading unit is loaded with the front and back turned upside down.

Here, the "read result" means, for example, "the reading means has finished reading after reading the loaded disc" or "the reading means tried to read the loaded disc but could not read it. Things. " According to the present invention, when one of the reading units reads the loaded disk and the reading is completed, the disk can be automatically loaded to the other reading unit. Accordingly, even when a user or the like stores a double-sided disc in the storage means, both sides of the disc can be reproduced. Further, according to the present invention, when one of the reading means cannot read the disc, the disc can be automatically loaded on the other reading means. Therefore, according to the present invention, even a single-sided disc can be reproduced. Therefore, users can use a single-sided disc,
It can be stored in the storage means without worrying about its front and back. That is, the user does not need to take out the disk stored upside down once.

According to a fifth aspect of the present invention, in the disk device according to the fourth aspect, the first means for operating the replacement means when the one of the disks loaded by the loading means cannot be read. (For example, the CPU 20 shown in FIGS. 12 and 13: step S28) is provided in the control means.

As described above, according to the fifth aspect of the present invention, when one of the reading means cannot read the loaded disk, the replacement means operates, so that the disk loaded on one of the reading means can be operated. Is loaded on the other reading means. Here, the surface read by the other reading unit is the opposite surface to the surface read by the one reading unit. Therefore, even when the single-sided disk is stored in the storage means upside down, the single-sided disk can be reproduced. In addition, even if the content recorded on the surface read by the reading means on a double-sided disk instead of a single-sided disk is damaged, the opposite surface can be reproduced. Accordingly, the user can store a single-sided disc or the like in the storage means without worrying about the front and back.

According to a sixth aspect of the present invention, in the disk device according to the fifth aspect, a transport unit (for example, as shown in FIG. 11) for transporting the disk loaded on the first reading unit or the second reading unit to the storage unit. And a second means for operating the transport means when the other cannot read the disc loaded on the other side by the replacement means (for example, as shown in FIGS. 12 and 13). CPU 20 shown: Step S3
3) The control means has the feature.

As described above, according to the sixth aspect of the present invention, when the other reading means cannot read the inverted loaded disc, the disc is conveyed to the storage means. Therefore, even if a disc on which information is not recorded on both sides or a disc whose information is broken on both sides is loaded, the disc is automatically returned to the storage means. Therefore, even when a user or the like stores a disc on which both sides are not recorded in the storage means, the state in which the disc is loaded on the reading means is not maintained.

At this time, the disk is clamped so that the center of the disk is the rotation axis of the turntable 9. Then, the disk rotates when the motor 10 rotates the turntable 9. Further, when the disk is rotating, the optical pickup 11 is moved in the radial direction of the disk by the pickup moving mechanism 12, the optical pickup 11 focuses on the surface of the disk, and the optical pickup 11 reads the signal of the disk. .

Next, the loading mechanism 6 will be described. The loading mechanism 6 includes a loading chassis 18 that extends on a line corresponding to the rotation diameter of the rotary stocker 5 so as not to hinder the rotation of the rotary stocker 5, a chucking mechanism 14 that is slidably provided with respect to the loading chassis 18, and And a loading drive mechanism 19 (shown in FIG. 3) for moving the chucking mechanism 14 with respect to the loading chassis 18.

The loading chassis 18 is fixed to the main chassis 7 of the disk drive 1. And
In a plan view, the loading chassis 18 is provided so as to cross the rotary stocker 5 according to the rotation diameter of the rotary stocker 5. The chucking mechanism 14
The disc can be chucked (grabbed), and the disc can be released from chucking. The chucking mechanism 14 is movable according to the diameter of the rotary stocker 5 in a plan view, and is movable from one end to the other end of the loading chassis 18. Also,
The turntable 9 is arranged near the track of the chucking mechanism 14 in a plan view, and the chucking mechanism 14 can move to a position corresponding to the turntable 9. The chucking mechanism 14 is moved with respect to the loading chassis 18 by a loading drive mechanism 19.

In the loading drive mechanism 19 configured as described above, the disc located at one end or the other end of the loading chassis 18 is moved to the chucking mechanism 14.
Releases the chucking of the disc while chucking. When the chucking mechanism 14 is located at the position corresponding to the turntable 9, the chucking mechanism 14 chucks the disk at this position and releases the chucking of the disk.

Next, the loading operation and the reversing operation of the disc changer device 3 will be described.

The loading operation of the disc changer device 3 is as follows. That is, when the rotary stocker driving mechanism 17 rotates the rotary stocker 5, one of a plurality of or a single disk stored in the rotary stocker 5 can be placed at one end (the other end) of the loading chassis 18. )).
Next, the chucking mechanism 14 at one end of the loading chassis 18 chucks the disc located at the one end. Subsequently, the loading drive mechanism 19 moves the chucking mechanism 14 to move the chucked disk together with the chucking mechanism 14 to a position corresponding to the turntable 9.

Next, the contact / separation mechanism is operated to move the clamper 13 in the direction of contact with the turntable 9 to clamp the disk. When the disk is clamped, the chucking mechanism 14 releases the chucking of the disk. The above is the loading operation. When the clamped disc is stored in the rotary stocker 5, the operation is reversed (hereinafter, this operation will be referred to as an eject operation).

On the other hand, the reversing operation of the disc changer device 3 is as follows. That is, when a disc is loaded from one end of the loading chassis 18 (at this time, it is assumed that the A side of the disc faces the optical pickup 11), the groove 15 in which the disc is stored is inserted into the groove of the loading chassis 18. The rotary stocker driving mechanism 17 rotates the rotary stocker 5 so as to be located at the other end. Next, the chucking mechanism 14
Chucks the loaded disc at a position relative to the turntable 9. Next, the contact / separation mechanism operates, and the contact / separation mechanism releases the clamper 13 with respect to the turntable 9 to release the clamp of the disk.

Next, the loading drive mechanism 19 moves the disk together with the chucking mechanism 14 to the other end of the loading chassis 18 and stores the disk in the groove 15. Then, the chucking mechanism 14 releases the chucking of the disk at the other end. Next, the rotary stocker driving mechanism 17 operates the rotary stocker 5.
By rotating the loading chassis 18, the disc located at the other end of the loading chassis 18 is moved.
To one end. At this time, the loading drive mechanism 19 moves the chucking mechanism 14 from the other end of the loading chassis 18 to one end.

Thereafter, the disc changer device 3 performs the same operation as the above-described loading operation to load the disc moved from the other end to the one end to the reproducing unit 2. The above is the reversing operation of the disc changer device 3, whereby the disc previously loaded on the reproducing unit 2 is turned over and further loaded on the reproducing unit 2 (B of the disc).
The surface faces the optical pickup 11).

Further, the disk device 1 has a carry-in / discharge mechanism (not shown). That is, the loading / unloading mechanism inserts a disk into the disk device 1 from an insertion port provided in the housing of the disk device 1, stores the disk in the free groove 15 of the rotary stocker 5, and The stored disk is discharged out of the disk device 1.

The control system of the disk device 1 according to the first embodiment will be described. As shown in FIG.
Is basically composed of a CPU 20 and a RAM 21
, A ROM 22, an interface (not shown), a drive circuit (not shown), and a system bus (not shown), and the respective components are connected to each other by the system bus so as to be able to input and output data.

The optical pickup 11 is connected to a system bus via an interface. Also,
The detection device 16 is connected to the system bus via the interface. Each of the motor 10, the pickup moving mechanism 12, the rotary stocker driving mechanism 17, and the loading driving mechanism 19 is connected to a system bus via a driving circuit.

The ROM 22 stores a control program for controlling the entire disk drive 1 and control data used in the control program in advance. CPU 20
Performs a control process based on a control program and control data stored in the ROM 22, an input signal from the detection device 16 or an input signal from the optical pickup 11. The RAM 21 is a storage unit used as a work area or the like of the CPU 20.

The pickup moving mechanism 12, the rotary stocker driving mechanism 17 or the loading driving mechanism 19 is driven based on the control processing of the CPU 20, and each of the pickup moving mechanism 12, the rotary stocker driving mechanism 17 and the loading driving mechanism 19 is driven. The drive is performed while the information is fed back to the CPU 20.

Further, the CPU 20 controls the optical pickup 11
Control processing is performed so that the disc is focused. When the optical pickup 11 reads the disk by focusing the disk, the result is C
This is fed back to the PU 20. And the CPU 20
Performs control processing of the entire disk device 1 based on the result read by the optical pickup 11.

Next, the flow of processing in the CPU 20 will be described.
This will be described with reference to the flowchart shown in FIG.

First, the CPU 20 determines which of the plurality of grooves 15, 15,... Contains a disk based on an input signal from the detection device 16 (step S1). Then, the CPU 20 selects one groove (hereinafter, referred to as a selection groove) from among the grooves accommodating the disk (step S2). As a result, one disk to be loaded into the reproduction unit 2 is determined from among a plurality of (or a single) disks stored in the rotary stocker 5.

Subsequently, the CPU 20 performs a loading control process (step S3). That is, the CPU 20 controls the rotary stocker driving mechanism 17 to operate, whereby the selection groove moves to one end of the loading chassis 18. Next, the CPU 20 controls the loading drive mechanism 19 to operate. As a result, the disc changer device 3 performs the above-described loading operation, and the disc stored in the selection groove is loaded on the reproducing unit 2.

Subsequently, the CPU 20 performs a disk read control process (step S4). That is, the CPU 20 controls the optical pickup 11 so as to focus on the loaded disc. At that time, the CPU 20 performs control for operating the pickup moving mechanism 12, whereby the pickup moving mechanism 12
Move 1 As a result, the optical pickup 11 reads the surface A of the disk, and the reading result of the optical pickup 11 is output to the control device 4.

After the loading control processing, the CPU 20
A determination is made based on the input reading result (step S
5). That is, the CPU 20 determines whether or not the optical pickup 11 has read the side A of the disk (whether or not the optical pickup 11 has focused on the side A of the disk). Then, when the CPU 20 determines that the optical pickup 11 has read the A side of the disk (step S
5: Yes), the optical pickup 11 and the pickup moving mechanism 12 are controlled so as to continue reading the surface A of the disk (step S6). This allows
The contents recorded on the disc are reproduced. Then, while the recorded content of the disc is being reproduced, the CPU 20 determines whether or not the optical pickup 11 has finished reading the A side of the disc (step S7). If it is determined that the reading has been completed (step S7: Yes),
The process of the CPU 20 proceeds to step S8, and if it is determined that the reading has not been completed (step S7: No), the optical pickup 11 and the pickup moving mechanism 12 are controlled so that the surface A of the disk is continuously read.
The PU 20 controls.

On the other hand, in step S5, if the optical pickup 11 cannot read the A side of the disk,
Is determined (Step S5: No), the CPU 2
The process of 0 moves to Step S8.

Then, in step S8, the CPU 2
0 performs the inversion control process. That is, the CPU 20 controls the rotary stocker driving mechanism 17 to operate, whereby the selection groove is moved from one end of the loading chassis 18 to the other end. Next, the CPU 20
Controls the loading drive mechanism 19 to operate, and by the operation of the loading drive mechanism 19, the loaded disk is stored in the selected groove. Next, the CPU 20 controls the rotary stocker driving mechanism 17 to operate, whereby the selection groove is moved from the other end of the loading chassis 18 to one end. Next, the CPU 20 controls the loading drive mechanism 19.
, So that the disc is loaded into the playback unit 2. Thus, CP
By the reversal control process of U20, the disc changer device 3 performs the reversal operation as described above.

After the inversion control processing, the CPU 20 performs a disk reading control processing (step S9). Thus, as in the case of step S4, the optical pickup 11 reads the surface B of the disk, but the reading result of the optical pickup 11 is output to the control device 4.

Subsequently, the CPU 20 makes a determination based on the input reading result (step S10). That is, CP
U20 determines whether or not the optical pickup 11 has read the B side of the disc (whether or not the optical pickup 11 has focused on the B side of the disc). If it is determined that the optical pickup 11 has read the B side of the disc (step S10: Yes), the CPU 20
Controls the optical pickup 11 and the pickup moving mechanism 12 so as to continue reading the B side of the disk (step S11). Thereby, the recorded contents of the disc are reproduced. When the recorded content of the disc is being reproduced, the CPU 20
Determines whether the reading of the B side of the disk has been completed (step S12). If it is determined that the reading has been completed (step S12: Yes), the process of the CPU 20 proceeds to step S13. If it is determined that the reading has not been completed (step S12: No), the CPU 20 controls the optical pickup 11 and the pickup moving mechanism 12 so as to continue reading the B side of the disk.

On the other hand, if the optical pickup 11 cannot read the side B of the disk at step S10,
0 (step S10: No), the CP
The process of U20 moves to step S13.

Then, in step S13, the CPU
20 performs an eject control process. That is, the CPU 20
Controls the loading drive mechanism 19 to operate. By the operation of the loading drive mechanism 19, the disc turned over is moved to the loading chassis 18.
Is stored in the selection groove located at the other end of the.

Subsequently, the CPU 20 determines whether or not to end the processing (step S14), and ends the processing (step S14: Yes). On the other hand, if the CPU 20 determines that the process is not to be ended (step S14: N
o), another groove is selected from the grooves (excluding the above-mentioned selected groove) in which the disk is stored (step S15). And
The process of the CPU 20 returns to Step S3. It should be noted that in step S14, the determination as to whether or not the processing ends
For example, it may be based on whether or not the disk has been reproduced in all the grooves in which the disks are stored, or whether or not a predetermined number of disks have been loaded.

As described above, according to the disk device 1 of the first embodiment, the following operation and effect can be obtained.
That is, the reading result of the optical pickup 11 is fed back to the control device 4 (step S4), and it is determined whether or not the optical pickup 11 has read the A side of the disk in step S5. Alternatively, the operation based on the processing in step S8 is automatically performed. In step S8, the disc is automatically reversed by the disc apparatus 1 from the side A to the side B of the disc and loaded. Therefore, no information is recorded on the A side of the disc (or it is damaged)
Even in this case, the B side of the disc is reproduced. Therefore, the user using the disk device 1 can store the disk in the rotary stocker 5 without worrying about the front and back of the disk even if the disk is recorded only on one side.

On the other hand, in step S6, when the disk device 1 can read the surface A of the disk, the disk device 1 continues reading the surface A of the disk. Therefore, the A
The face plays automatically. Thereafter, when the reading is completed, the processing proceeds from step S8 to step S9, the disk is turned over, and the disk device 1 tries to read the back surface (surface B) of the disk. Therefore, even if information is recorded on both sides of the disc, the disc is automatically reproduced.

The processing flow of the CPU 20 is as follows: step S5 → step S8 → step S9 → step S10
→ If it becomes step S13, another disk is loaded (step S15).

Further, each of the first loading mechanism 6, the second loading mechanism 6, the motors 10, 10, the pickup moving mechanisms 12, 12, and the rotary stocker driving mechanism 17 are connected to a system bus via a driving circuit.

The ROM 22 previously stores a control program for controlling the entire disk drive 1 and control data used in the control program. CPU 20
Performs a control process based on a control program and control data stored in the ROM 22, an input signal from the detection device 16 or an input signal from the optical pickup 11. The RAM 21 is a storage unit used as a work area or the like of the CPU 20.

Further, the CPU 20 controls the optical pickup 1
A control process is performed so as to focus the disc on the discs 1 and 11. Then, a result of reading the disk by the optical pickups 11 and 11 being focused on the disk is fed back to the CPU 20. Then, the CPU 20 performs control processing of the entire disk device 1 based on the result read by the optical pickup 11.

Next, the CPU according to the fourth embodiment will be described.
The flow of the process 20 will be described with reference to the flowchart shown in FIG.

First, the CPU 20 determines which of the plurality of grooves 15, 15,... Contains a disk based on an input signal from the detection device 16 (step S21). Then, the CPU 20 selects one groove (hereinafter, referred to as a selection groove) from among the grooves accommodating the disk (step S22). As a result, one disk to be loaded into the reproduction unit 2 is determined from among a plurality of (or a single) disks stored in the rotary stocker 5.

Subsequently, the CPU 20 performs a loading control process (step S23). That is, the CPU 20
Control is performed to operate the rotary stocker drive mechanism 17, whereby the selection groove moves to a position corresponding to the first reproduction unit 2. Next, the CPU 20 controls the first loading mechanism 6 to operate. Thereby, the first loading mechanism 6 loads the disc in the selected groove into the first reproducing unit 2.

After the loading control processing, the CPU 20
A disk reading control process is performed (step S24). That is, the CPU 20 controls the optical pickup 11 of the first reproducing unit 2 so as to focus on the loaded disc. At this time, the CPU 20 controls the operation of the pickup moving mechanism 12 of the first reproducing unit 2, whereby the pickup moving mechanism 12 of the first reproducing unit 2 moves the optical pickup 11. As a result, the optical pickup 11 of the first reproducing unit 2 reads the A side of the disk, but the reading result of the optical pickup 11 of the first reproducing unit 2 is output to the control device 4.

Subsequently, the CPU 20 makes a judgment based on the input reading result (step S5). That is, CPU
Reference numeral 20 denotes whether or not the optical pickup 11 of the first reproducing unit 2 has read the A side of the disc (optical pickup 11
Is possible to focus on the surface A of the disc). When the CPU 20 determines that the optical pickup 11 of the first reproducing unit 2 has read the A side of the disk (step S5: Yes), the optical pickup 1 continues reading the A side of the disk.
1 and the pickup moving mechanism 12 are controlled (step S26). Thereby, the recorded contents of the disc are reproduced. Then, while the recorded content of the disc is being reproduced, the CPU 20 determines whether or not the optical pickup 11 of the first reproducing unit 2 has finished reading the A side of the disc (step S27). If it is determined that the reading has been completed (step S27: Yes), C
The process of the PU 20 proceeds to step S28, and when it is determined that the reading has not been completed (step S27: No)
Then, the CPU 20 controls the optical pickup 11 and the pickup moving mechanism 12 of the first reproducing unit 2 so that the surface A of the disk is continuously read.

On the other hand, when the CPU 20 determines in step S25 that the optical pickup 11 of the first reproducing unit 2 cannot read the A side of the disc (step S2).
5: No), the process of the CPU 20 moves to step S28.

Then, in step S28, the CPU
20 performs a replacement control process. That is, the CPU 20 controls the first loading mechanism 6 to operate, and the disc loaded on the first reproducing unit 2 is ejected to the selected groove by the first loading mechanism 6.
Next, the CPU 20 controls the rotary stocker driving mechanism 1
7 is operated to move the selected groove to a position corresponding to the second reproducing unit 2. Then
The CPU 20 controls the second loading mechanism 6 to operate, whereby the second loading mechanism 6 loads the disc in the selected groove into the second reproducing unit 2. As described above, by the exchange control process of the CPU 20, the disc changer device 3 performs the above-described exchange operation, and the second reproducing unit 2 can reproduce the B side of the disk.

After the exchange control processing, the CPU 20 performs a disk read control processing (step S29). This allows
The optical pickup 11 of the second reproducing unit 2 reads the surface B of the disk, and the reading result of the optical pickup 11 of the second reproducing unit 2 is output to the control device 4.

Subsequently, the CPU 20 makes a determination based on the input reading result (step S30). That is, CP
U20 determines whether or not the optical pickup 11 of the second reproducing unit 2 has read the side B of the disc (optical pickup 1
1 is able to focus on the B side of the disc). If it is determined that the optical pickup 11 of the second reproducing unit 2 has read the B side of the disk (step S30: Yes), the CPU 20 of the second reproducing unit 2 continues to read the B side of the disk. The optical pickup 11 and the pickup moving mechanism 12 are controlled (Step S31). Thereby, the recorded contents of the disc are reproduced. Then, while the recorded content of the disc is being reproduced, the CPU 20 determines whether or not the optical pickup 11 of the second reproducing unit 2 has finished reading the B side of the disc (step S32), and the reading ends. (Step S32: Ye
In s), the process of the CPU 20 moves to step S33. If it is determined that the reading has not been completed (step S32: No), the CPU 20 controls the optical pickup 11 and the pickup moving mechanism 12 of the second reproducing unit 2 so as to continue reading the B side of the disk.

On the other hand, in step S30, if the second optical pickup 11 cannot read the side B of the disc,
When the PU 20 determines (step S30: No), the processing of the CPU 20 proceeds to step S33.

Then, in step S33, the CPU
20 performs an eject control process. That is, the CPU 20
Controls the second loading mechanism 6 to operate. Then, by the operation of the second loading mechanism 6,
The disc loaded in the second reproducing unit 2 is stored in the selected groove.

Subsequently, the CPU 20 determines whether or not to end the processing (step S34), and ends the processing (step S34: Yes). On the other hand, if the CPU 20 determines that the processing is not to be ended (step S34: N
o), another groove is selected from the grooves (excluding the above-mentioned selected groove) in which the disk is stored (step S35). And
The process of the CPU 20 returns to Step S23. In step S34, it is determined whether or not the processing is completed, for example, by determining whether or not the disk has been reproduced in all of the grooves in which the disk is stored, or by determining whether or not a predetermined number of disks have been reproduced. It may be based on whether or not loading is performed.

As described above, according to the disk device 1 of the fourth embodiment, the following operation and effect can be obtained.
That is, the reading result of the optical pickup 11 of the first reproducing unit 2 is fed back to the control device 4 (step S2).
4) In step S25, it is determined whether or not the optical pickup 11 of the first reproducing unit 2 has read the A side of the disk, so that the disk device 1 executes step S2.
6 or the operation based on the process of step S28 is automatically performed. By the operation based on step S28,
The disc is moved from the first playback unit 2 to the second playback unit 2
Is automatically replaced by. Therefore, even if no information is recorded on the A side of the disc, the B side of the disc is reproduced. Therefore, the user using the disk device 1 can store the disk in the rotary stocker 5 without worrying about the front and back of the disk even if the disk is recorded only on one side.

On the other hand, in step S26, when the A side of the disk can be read, the A
