Such acquisition determination can be made based on whether or not the identification information has been acquired after a predetermined time has elapsed since the transmission of the identification information request command. This time may be set as appropriate.
If the main control unit 731 determines that the identification information has not been acquired, the main control unit 731 generates and outputs a control signal indicating an error to the display control unit 744 of the drive control system 74. Upon receiving this control signal, the display control unit 744 generates an error message, displays the error message on the display unit 3 (processing S31), returns to processing S12, and obtains identification information for the other disks 9. Process S12 is executed.
Note that the message when the process moves from the process S13 to the process S31 is a message that the disk 9 that can receive the identification information does not exist around the disk device 1.

On the other hand, when the main control unit 731 determines that the identification information has been acquired, the main control unit 731 outputs a control signal to the information determination unit 733, and the information determination unit 733 transmits the identification information. It is determined whether the disc 9 corresponds to the disc device 1, that is, whether the disc device 1 can reproduce or record (processing S14). Specifically, in process S14, the information determination unit 733 determines media information and information type information included in the identification information. This determination result is output from the information determination unit 733 to the main control unit 731.
If the information determination unit 733 determines that the disk 9 does not correspond to the disk device 1, the main control unit 731 outputs a control signal indicating an error to the display control unit 744. Upon receiving this control signal, the display control unit 744 generates an error message, displays the error message on the display unit 3 (processing S31), returns to processing S12, and obtains identification information for the other disks 9. Process S12 is executed.
Note that the message when the process shifts from the process S14 to the process S31 is a message that the disc 9 that can be reproduced or recorded does not exist around the disc device 1.

On the other hand, when the information determination unit 733 determines that the disk 9 is compatible with the disk device 1, the main control unit 731 outputs a control signal for causing the display control unit 744 to display identification information. The display control unit 744 to which this control signal is input forms an image including the title name and media information included in the identification information, and displays the image on the display unit 3 (process 15).
After this process S15, the main control unit 731 outputs a control signal to the open / close control unit 743 of the drive control system 74. The open / close control unit 743 to which the control signal is input drives the tray driving motor 25 to cause the disk tray 23 to protrude from the disk storage unit 2 to open the disk storage unit 2 (processing S16). The system waits for the disk 9 to be installed (process S17). That is, the main control unit 731 and the opening / closing control unit 743 correspond to the opening operation control unit of the present invention.

Through the processing S17, the main control unit 731 in the installation standby state of the disk 9 monitors the signal from the disk detection unit 24, and determines whether or not the disk 9 is installed and mounted on the disk tray 23 (processing S18).
Here, when the main control unit 731 determines that the disk 9 is not installed from the signal input from the disk detection unit 24, the process returns to the processing S17 and waits for the installation of the disk 9 on the disk tray 23.
On the other hand, when the main control unit 731 determines that the disk 9 has been installed, the main control unit 731 outputs a control signal to the tag communication unit 5, and a disk by the strong radio wave transmission / reception unit of the tag communication unit 5. The transmission / reception of commands to / from the RFID tag 93, that is, communication with the RFID tag 93 is restricted (step S19). That is, the main control unit 731 corresponds to an information acquisition restriction unit of the present invention.
As a result, it is possible to prevent identification information from being received from another disk 9 that can communicate with the disk device 1, and to prevent inconsistency between the disk 9 and the identification information. Further, since communication restriction is performed, unnecessary power consumption can be suppressed, and power saving of the disk device 1 can be achieved.

After this process S19, as shown in FIG. 6, the main controller 731 again executes the identification information acquisition process from the disk 9 installed on the disk tray 23 (identification information reacquisition process S20). That is, the main control unit 731 corresponds to the information reacquisition unit of the present invention.
In this process S20, except that communication with the RFID tag 93 is performed via the weak radio wave transmission / reception unit of the tag communication unit 5 and communication is performed only with the RFID tag 93 of the disk 9 installed on the disk tray 23. Since it is substantially the same as the above-described process S12, description thereof is omitted.
By this identification information reacquisition process S20, the identification information corresponding to the disk 9 to be reproduced or recorded can be reliably acquired, so that malfunction of the disk device 1 can be suppressed and at the time of reproduction, The image quality and sound quality can be set accordingly.

After the identification information reacquisition process S20, the main control unit 731 determines whether or not the identification information has been received (process S21), similarly to the process S13 described above.
If the main control unit 731 determines that the identification information has not been received from the disk 9 stored in the disk storage unit 2, the main control unit 731 sends a control signal indicating an error to the display control unit 744. Then, an error message is displayed on the display unit 3 (process S32), and the reproduction / recording standby process S is terminated.
Note that the message when the process shifts from the process S21 to the process S32 is a message that the identification information cannot be acquired from the disk 9 stored in the disk storage unit 2.

On the other hand, when the main control unit 731 determines that the identification information has been received, the information determination unit 733 determines that the disk 9 installed on the disk tray 23 corresponds to the disk device 1 as in the above-described processing S14. (Step S22), and outputs the determination result to the main control unit 731.
If the information determination unit 733 determines that the disk 9 does not correspond to the disk device 1, the main control unit 731 outputs a control signal indicating an error to the display control unit 744 to display the display unit. 3 displays an error message (process S32), and ends the reproduction / recording standby process S.
The message when the process shifts from the process S22 to the process S32 is a message that the disk 9 installed in the disk tray 23 does not correspond to the disk device 1.

On the other hand, when the information determination unit 733 determines that the disk 9 installed on the disk tray 23 corresponds to the disk device 1, the main control unit 731 outputs a control signal to the open / close control unit 743. The open / close control unit 743 to which the control signal is input drives the tray driving motor 25 to immerse the disk tray 23 in the disk storage unit 2 and close the disk storage unit 2 (processing S23). As a result, the disk 9 whose identification information has been acquired by the main control unit 731 is stored in the disk storage unit 2. That is, the main control unit 731 and the opening / closing control unit 743 correspond to the closing operation control unit of the present invention.
If it is determined by such processing S23 that the disc 9 can be reproduced / recorded from the identification information, the disc tray 23 on which the disc 9 is installed is inserted into the disc storage portion 2 and the disc is inserted. Since the disk is automatically stored in the disk storage unit 2, the user's operation can be simplified. Therefore, even an inexperienced user can easily operate the disk device 1.
Note that the opening and closing operations of the disc storage unit 2 are not shown, but can also be performed by the user.

After this processing S23, the main control unit 731 outputs a control signal to the information determination unit 733, and the information determination unit 733 determines the information type and the like included in the acquired identification information, and stores it in the disc storage unit 2. It is determined whether the stored disk 9 is a reproduction disk in which information has already been recorded in the recording unit 92 or a recording disk in which information can be added to the recording unit 92 (processing S24). The determination result is output to the main control unit 731.
Here, when the main control unit 731 determines from the determination result of the information determination unit 733 that the disk 9 is a recording disk, the information recording standby state for the disk 9 is set as a standby state (process S41), and reproduction / reproduction is performed. The recording standby process S is terminated.
On the other hand, when the main control unit 731 determines that the disc is a playback disc, the main control unit 731 outputs a control signal to the detailed information acquisition unit 734, and the detailed information acquisition unit 734 causes the HDD 6. Alternatively, detailed information is acquired from an information distribution device on the network (processing S25).

FIG. 8 is a diagram showing a process flow of the detailed information acquisition process S25 by the detailed information acquisition unit 734.
In the detailed information acquisition process S25, the detailed information acquisition unit 734 first outputs a drive signal to the HDD control unit 746 of the drive control system 74 to drive the HDD 6. Then, detailed information including setting information corresponding to the title information and the unique code included in the identification information acquired from the disk 9 stored in the disk storage unit 2 is retrieved from the HDD 6 (processing S251). It is determined whether information is recorded (step S252).
If the detailed information acquisition unit 734 determines that the detailed information corresponding to the identification information is recorded in the HDD 6, the detailed information is acquired (step S255).

On the other hand, when the detailed information acquisition unit 734 determines that the detailed information is not recorded, the detailed information acquisition unit 734 determines whether communication connection to the information distribution apparatus on the network is possible via the network interface 72 (processing S253). .
Here, when the detailed information acquisition unit 734 determines that the network connection is not possible, the detailed information acquisition process ends, and the detailed information acquisition unit 734 outputs the processing result to the main control unit 731.
On the other hand, when the detailed information acquisition unit 734 determines that the network connection is possible, the detailed information acquisition unit 734 determines whether the detailed information can be acquired by accessing the information distribution apparatus on the network (processing S254).

Here, when the detailed information acquisition unit 734 determines that acquisition of detailed information from the information distribution apparatus is impossible, the network connection is cut off, and the detailed information acquisition process ends. This processing result is output from the detailed information acquisition unit 734 to the main control unit 731. Such determination processing measures the elapsed time after outputting the detailed information request signal to the information distribution apparatus, and determines whether or not there is a response from the information distribution apparatus after a predetermined time has elapsed. be able to. The time may be set as appropriate.
On the other hand, when the detailed information acquisition unit 734 determines that the detailed information can be acquired from the information distribution apparatus, the detailed information according to the acquired identification information is acquired from the information distribution apparatus (processing S255). ).

After this process S255, the detailed information acquisition unit 734 determines whether the acquired detailed information is acquired from the HDD 6 or acquired from the network (process S256).
If the detailed information is acquired from the HDD 6, the detailed information acquisition unit 734 ends the detailed information acquisition process S 25 and outputs the processing result to the main control unit 731.
On the other hand, when the detailed information is acquired via the network, the detailed information acquiring unit 734 records the acquired detailed information in the HDD 6 via the HDD control unit 746 so as to correspond to the identification information. (Process S257), the detailed information acquisition process is terminated. This processing result is output from the detailed information acquisition unit 734 to the main control unit 731.

  By such detailed information acquisition processing S25, detailed information including setting information corresponding to the identification information of the disc 9 related to reproduction or recording can be acquired. Therefore, image quality setting and / or sound quality setting suitable for the disc 9 can be obtained. Processing can be performed. Further, since it is not necessary for the user to make such settings each time the disk 9 is reproduced, the operability of the disk device 1 can be further improved. Further, when the detailed information is not recorded in the HDD 6, the detailed information is acquired by accessing the information distribution apparatus on the network, so that it is possible to deal with various disks, and the information recorded on the disk is included in the information recorded on the disk. The corresponding setting can be automatically performed.

After the detailed information acquisition process S25, the main control unit 731 determines whether the detailed information has been acquired as shown in FIG. 6 (process S26).
If the main control unit 731 determines that the detailed information has not been acquired, an error signal is output to the display control unit 744, and the display control unit 744 displays an error message on the display unit 3. (Process S32), the reproduction / recording standby process S is terminated.
Note that the message when the process proceeds from the process S26 to the process S32 is a message indicating that the detailed information could not be acquired.
On the other hand, if the main control unit 731 determines that the detailed information has been acquired, the information processing unit 735 is set according to the image quality information and / or the sound quality information included in the detailed information (step S27). The reproduction / recording standby process S is terminated.

When the disk device 1 detects the disk 9 corresponding to the disk device 1 by the reproduction / recording standby process S as described above, the disk tray 23 is automatically opened to open the disk storage unit 2. Therefore, the disk 9 can be easily stored in the disk storage portion 2. As a result, even a person unfamiliar with the operation of the disk device 1 can easily operate the disk device 1.
When the disk 9 corresponding to the disk device 1 is installed in the disk tray 23, the disk tray 23 automatically closes and the disk 9 is stored in the disk storage unit 2. The operability can be further improved.

Further, when reproducing the disk 9, detailed information corresponding to the identification information recorded on the RFID tag 93 of the disk 9 is acquired, and setting information included in the detailed information, that is, image quality setting information and / or sound quality setting information. Therefore, it is possible to perform reproduction suitable for the video information and / or audio information recorded on the disk 9.
Such detailed information can be acquired from an information distribution apparatus on the network, and the acquired detailed information can be recorded in the HDD 6, so that it can correspond to various disc 9 identification information. Further, since the HDD 6 is provided, it is possible to record the detailed information acquired from the information distribution apparatus, so that it is not necessary to connect to the network every time the disk 9 is reproduced, so that the operability can be further improved. .

  In addition, when the image quality setting and / or the sound quality setting at the time of disc playback is changed by the user's operation, the detailed information is generated as the image quality setting information and the sound quality setting information according to the image quality setting and the sound quality setting. . The image quality information and the sound quality information included in the detailed information recorded in the HDD 6 are updated by the image quality setting information and the sound quality setting information. According to this, since it is possible to prevent the detailed information set by the user from being set again, it is possible to execute the playback setting according to the user's preference. Therefore, the operability of the disk device 1 can be further improved.
