  However, in the above-described conventional configuration, the operation for erasing information recorded on the recording medium is not considered. For this reason, if the recording medium on which the information for which the user has issued an erasure instruction is recorded is not loaded, the recording medium must be loaded, and the erasure instruction is issued due to the time required for loading. After that, there is a problem that it takes time to complete the erasure.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to record on a recording medium in a recording apparatus that detachably stores a plurality of recording media and performs recording on the recording medium. It is an object of the present invention to provide a recording apparatus capable of shortening a user's experience time relating to erasure of recorded information.

  In order to solve the above-described problems, a recording apparatus according to the present invention stores information that is a part of a plurality of recording media stored in the storage unit and a storage unit that detachably stores a plurality of recording media. A recording apparatus that includes a recording unit that mounts a target recording medium to be recorded and records the information on the target recording medium, and a change unit that switches the target recording medium. An acquisition means for acquiring an erasure instruction for erasing at least one piece of information recorded as erasure target information, a storage unit for storing the erasure instruction acquired by the acquisition means, and the acquisition means instructing the erasure instruction When the recording medium on which the erasure target information indicated by the erasure instruction is recorded is not attached to the recording unit at the time of acquisition, the operation finger that becomes the operation target is the recording medium on which the erasure target information is recorded. Alternatively, when an instruction to turn off the main power supply is acquired so that the own apparatus enters a standby state, the erasure target information indicated by the erasure instruction stored in the storage unit or the erasure target in the recording medium Control means for controlling the recording unit and the changing unit so as to erase the management information indicating the recording position of the information is provided.

  In order to solve the above problems, a control method according to the present invention includes a storage unit that detachably stores a plurality of recording media, and information that is a part of the plurality of recording media stored in the storage unit. A method for controlling a recording apparatus, comprising: a recording unit that mounts a target recording medium to be recorded; records the information on the target recording medium; and a changing unit that switches the target recording medium. An acquisition step of acquiring an erasure instruction for erasing at least one information recorded on any of the media as erasure target information, a storage step of storing the erasure instruction acquired in the acquisition step in a storage unit, and When the erasure instruction is acquired in the acquisition step, the erasure object information is recorded when the recording medium on which the erasure object information indicated by the erasure instruction is recorded is not mounted on the recording unit. The erasure target indicated by the erasure instruction stored in the storage unit triggered by the acquisition of an operation instruction for the recorded recording medium to be operated or an instruction to turn off the main power so that the own device enters a standby state And a control step of controlling the recording unit and the changing unit so as to erase the information or the management information indicating the recording position of the erasure target information on the recording medium.

  According to said structure, a some recording medium is accommodated in the accommodating part so that attachment or detachment is possible. The recording unit mounts a target recording medium, which is a part of the recording medium, and records information on the target recording medium. In other words, the recording unit records information on a smaller number of recording media than the largest recording medium that can be accommodated by the recording device in one recording opportunity.

  In order to record information on a larger number of recording media than the recording unit, the changing unit changes the target recording medium mounted on the recording unit. For example, the changing unit changes the recording medium loaded (loaded) in the drive device as the recording unit.

  In order to change the recording medium to be recorded, it is necessary to physically move the storage unit or the recording medium, so it takes time to change the recording medium.

  On the other hand, the acquisition unit acquires an erasure instruction for erasing erasure target information that is information to be erased. The erasure target information is at least one piece of information recorded on any one of a plurality of recording media, and may be plural. The erasure instruction acquired by the acquisition unit is stored in the storage unit.

  The control means records information on the target recording medium by controlling the recording unit and the changing unit, or erases information on the target recording medium. The control unit records the erasure target information when the recording unit on which the erasure target information indicated by the erasure instruction is recorded is not attached to the recording unit when the acquisition unit acquires the erasure instruction. The erasure target indicated by the erasure instruction stored in the storage unit triggered by the acquisition of an operation instruction for the recorded recording medium or an instruction to turn off the main power of the local device so that the local device enters a standby state Delete information or its management information.

  By this erasure process, the erasure target information is substantially erased from the recording medium. When using a recording medium that manages information recorded on itself using management information, the recording (reproducing) device can store the information to be erased only by erasing the corresponding management information without erasing the information to be erased. Recognize that it has been erased. Therefore, the corresponding management information may be deleted without deleting the information to be deleted.

  As described above, when the erasing instruction is input and the recording medium on which the erasing target information is recorded is not loaded in the recording unit, the erasing target information is not erased by changing the recording target recording medium. Instead, the erasure target information indicated by the erasure instruction or its management information is erased at a predetermined timing thereafter. The predetermined timing is a point in time when an operation instruction for the recording medium on which the erasure target information is recorded becomes an operation target or an instruction to turn off the main power of the own apparatus so that the own apparatus enters a standby state. .

  If an operation instruction for inputting a recording medium on which the erasure target information is recorded is input, and the erasure target information is erased when the recording medium is mounted on the recording unit, the erasure target information is erased. Therefore, the operation of mounting the recording medium on the recording unit can be omitted.

  In addition, when the main power supply in which the self apparatus is in a standby state is off, the self power supply apparatus does not accept instructions related to the recording (playback) operation from the user except for reserved recording and reserved reproduction. Even when the recording medium on which the information to be erased is recorded is mounted on the recording unit in the off state, it is very unlikely that the user will wait by interrupting the operation instructed by the user. Also, normally, in the standby state, the user does not pay attention to the recording device.

  Therefore, the waiting time of the user who issued the erasure instruction can be shortened as compared with the case where the erasure target information is erased when the erasure instruction is input.

  Further, a display list generating means for generating a display list for displaying a list of information recorded in the plurality of recording media on a display device connected to be communicable with the own device, and the display list generation Display control means for displaying the display list generated by the means on the display device, and by the control means, the erasure object information indicated by the erasure instruction stored in the storage unit, or the erasure object information Before the management information is erased, it is preferable that the display list generation unit deletes information related to the erasure target information indicated by the erasure instruction acquired by the acquisition unit from the display list.

  According to the above configuration, the display list generation unit generates a display list for displaying a list of information recorded in a plurality of recording media on a display device connected to the own device, and the display control unit Displays the display list on the display device. Then, the display list generation unit obtains information (for example, a video title) related to the deletion target information indicated by the deletion instruction from the display list before the control unit deletes the deletion target information or the management information of the deletion target information. delete.

  Therefore, by deleting the name of information that the user has instructed to delete from the display list, even if the information is not actually deleted, it can be shown to the user as if it had been deleted. It is possible to prevent the user from being confused by displaying the name of the information that should have been displayed.

  Further, it is preferable that the operation instruction is an instruction to record information on the recording medium on which the erasure target information indicated by the erasure instruction stored in the storage unit is recorded.

  According to the above configuration, the erasure target information is erased when the recording medium is loaded in the recording unit in order to record information on the recording medium in which the erasure target information is recorded.

  Therefore, it is possible to omit the operation of mounting the recording medium on the recording unit in order to erase the erasure target information, and it is possible to shorten the time required for erasing the erasure target information.

  The information processing apparatus further includes a reproduction unit that reproduces information of a target recording medium that is a target of information reproduction, which is a part of the plurality of recording media stored in the storage unit, and the operation instruction is stored in the storage unit. It is preferable that the reproduction unit reproduces information recorded on the recording medium on which the erasure target information indicated by the erase instruction is recorded.

  According to the above configuration, the erasure target information or the erasure target information indicated by the erasure instruction is selected while the recording medium on which the erasure target information or its management information is recorded is selected as the recording target of the recording unit or the playback target of the playback unit. Management information is deleted. That is, the erasure target information or its management information is erased when a recording medium on which the erasure target information or its management information is recorded is loaded in the recording unit as the target recording medium.

  Therefore, there is no need to change the target recording medium again in order to erase the erasure target information or its management information, and the time for erasing the erasure target information or its management information can be shortened.

  Further, it is preferable that the operation instruction is an instruction to eject the recording medium on which the erasure target information indicated by the erasure instruction stored in the storage unit is recorded from the own apparatus.

  According to the above configuration, when an instruction to eject the recording medium on which the erasure target information is recorded is acquired from the own device before erasing the erasure target information or the management information, the recording medium is ejected. Before the deletion, the erasure target information or the management information is erased via the recording unit.

  Therefore, it is possible to prevent the recording medium on which the erasure target information is recorded before erasing the erasure target information or its management information from being ejected from the apparatus. Therefore, it is possible to prevent the user from being confused by the information that the user should have instructed to erase is reproduced by another recording / reproducing apparatus.

  In addition, while the control unit erases the erasure target information or the management information via the recording unit, the control unit is provided with a message indicating the operation state of the own device or a message prompting the user to wait. It is preferable to further include display control means for displaying on the displayed display unit, the display device connected to the device itself, or both.

  When erasing the erasure target information or its management information when an instruction to eject the recording medium with the erasure target information recorded from its own device is input, it takes time to erase the information. It takes more time than the discharging operation.

  According to the above configuration, when erasing the erasure target information or its management information when the instruction to eject the recording medium on which the erasure target information is recorded is input, the display control means While deleting the information to be deleted or its management information, a message indicating the operation state of the own device or a message prompting the user to wait is displayed on the display unit provided in the own device or a display device connected to the own device. Or display both.

  Therefore, it is possible to prevent the user from being confused with respect to the fact that it takes longer than the normal recording medium ejection operation.

  Also included in the technical scope of the present invention are a control program for operating the recording apparatus, a control program for causing a computer to function as each of the means, and a computer-readable recording medium on which the control program is recorded. It is.

The file management information 221 includes the file name of the file, the position (sector number) where the file is recorded, the file size, the recording date and time, and the like.

  Each file need not be recorded in consecutive sectors, and may be divided into a plurality of partial data. In this case, the position information of each partial data is recorded as file management information 221 in association with the file name. The partial data is recorded from the head of successive sectors, and the position of the partial data is managed by the sector number of the head sector and the length of the partial data.

  The user data area 220 includes a data area 222 for recording data such as program data used by the user. The data area 222 includes an audio / video data area 223. In the audio / video data area 223, control information 224, a video object 225, a picture object 226, and an audio object 227 are recorded.

  The control information 224 is control information necessary when performing various processes such as recording (recording), reproduction, editing, and search. The video object 225 is recording information (moving image data) of the contents of the video data. The picture object 226 is information about a still image such as a slide or a still, information for searching a desired place in the video data, and information for an editing thumbnail in the video data. The audio object 227 is recording information of contents of audio data.

  The control information 224 includes a video manager 228. The video manager 228 is control information necessary for performing processing such as recording (recording), playback, editing, and search of each video title set (VTS) 229 included in the video object 225. Specifically, the video manager 228 includes the version number of the standard adopted by the optical disc 20, the free capacity (recordable capacity) of the optical disc 20 on which each video title set 229 is recorded, the number of video title sets 229, and the like. It is recorded.

  The video manager 228 is recorded near the beginning of the data area 222 (inner circumference side of the optical disc 20), and the recording / reproducing apparatus 1 reads the lead-in area 210, file management information 221, video manager 228 when the optical disc 20 is loaded. This information is read in the order of.

  Each video title set 229 includes video data compressed according to the MPEG standard, audio data compressed according to a predetermined standard or uncompressed audio data, and run-length compressed sub-picture data, and information for reproducing these data. Is stored. There are as many video title sets 229 as the number of recorded videos, and the video title sets 229 may be distributed and recorded in the data area 222.

(Details of table generation processing in the management table generation unit 53)
FIG. 7A is a diagram showing an example of the disc information management table 42, and FIG. 7B is a diagram showing an example of the disc recording information management table 41.

  As described above, the recording / reproducing apparatus 1 reads the information in the order of the lead-in area 210, the file management information 221, and the video manager 228 when loading the optical disc 20. At this time, the management table generation unit 53 reads the type, recording capacity, and remaining recording capacity (empty capacity) of the optical disc 20 from the lead-in area 210, and creates a disc information management table 42 that shows these pieces of information for each optical disc 20.

  At this time, the optical disk 20 set in the tray 15a is recognized as disk No. 1 (D1), and the optical disks 20 set in the trays 15b, 15c, and 15d are respectively set as disk Nos. 2 to 4 (D2 to D4). recognize. That is, the management table generating unit 53 manages each optical disc 20 in association with the number of the tray 15 in which the optical disc 20 is set. Therefore, as shown in FIG. Is associated with the disk number.

  Since the remaining recording capacity is recorded in the video manager 228, the management table generating unit 53 may read the remaining recording capacity from the video manager 228. Further, the management table generation unit 53 calculates the remaining recording capacity by subtracting the data amount recorded at that time in the data area 222 from the recording capacity of the optical disc 20 recorded in the lead-in area 210. Good.

  In addition, the management table generating unit 53, for each program recorded as each video title set 229 from the video manager 228 (and each video title set 229) when loading the optical disc 20, records the recording date and recording quality of the program. Then, the channel (CH) of the television station where the program is broadcast, the title of the program, and the data capacity of the program are read, and a disc recording information management table 41 indicating these pieces of information is created. Note that, as shown in FIG. Is granted.

  When the optical disk 20 is removed from the turntable 12, the management table generating unit 53 deletes management information corresponding to the removed optical disk 20 from the disk information management table 42 and the disk recording information management table 41.

(Details of the deletion instruction recording process in the management table generating unit 53)
When a user inputs an erasure instruction for erasing a program recorded on any of the optical disks 20 stored in the recording / reproducing apparatus 1 using the remote controller 21, the erasure instruction is managed via the controller 56. The data is output to the table generation unit 53.

  When receiving the erasure instruction, the management table generating unit 53 writes erasure target setting information indicating that the program indicated by the erasure instruction is an erasure target in the disk recording information management table 41. This erasure target setting information may be indicated by, for example, a flag of “0” (non-target) or “1” (erasure target). FIG. 7B shows a state where all programs are not to be erased.

  The erasure target setting information indicating the erasure target is not necessarily recorded in the disk recording information management table 41, and may be recorded as a table different from the disk recording information management table 41.

(Details of processing in display list generation unit 52)
FIG. 8 is a schematic diagram illustrating an example of a program list displayed on the display device 24. As shown in the figure, the program list is a list showing details of programs that are not to be erased among the programs shown in the disk recording information management table 41, and is a list recorded in the display list 44. is there. The biggest difference between the display list 44 and the disc recording information management table 41 is that the display list 44 does not show the program to be deleted.

  Thereby, it is possible to prevent the user from being confused by displaying the program name that should have been deleted by the user.

  In order to realize this configuration, the display list generation unit 52 displays a program to be deleted when the management table generation unit 53 records the deletion target setting information indicating the deletion target in the disk recording information management table 41. Delete from the display list 44. The program list indicated by the display list 44 is displayed on the display device 24 by the display control unit 54.

(Processing flow in the recording / reproducing apparatus 1)
Next, an example of the processing flow in the recording / reproducing apparatus 1 will be described with reference to FIGS. FIG. 9 is a flowchart illustrating an example of a processing flow in the recording / reproducing apparatus 1.

  When erasing information recorded on the optical disc 20, there are a method of erasing the information itself and a method of erasing management information of the information, and the latter method is generally used. Hereinafter, a case where the file management information 221 of information to be erased (erasure target information) is erased from the optical disc 20 in which the information to be erased is recorded will be described as an example. By erasing the file management information 221 of the erasure target information, the recording / reproducing apparatus cannot recognize the existence of the erasure target information, so that the erasure target information itself is erased from the optical disc 20.

  First, a signal that causes the display device 24 to display a list of all programs (program list) recorded on all optical discs 20 stored in the recording / reproducing apparatus 1 by the user using the remote controller 21 with respect to the recording / reproducing apparatus 1. Is input (S1).

  The signal is input to the reception signal analysis unit 55 via the infrared transmission / reception unit 2. The received signal analysis unit 55 analyzes the signal and outputs an instruction (display instruction) obtained by the analysis to the controller 56. The controller 56 outputs the display instruction to the display control unit 54.

  Upon receiving the display instruction, the display control unit 54 acquires the display list 44 stored in the auxiliary storage unit 4 and displays the program list indicated by the display list 44 on the display device 24 as shown in FIG. (S2).

  The user designates erasure target information (erasure target program) by operating the remote controller 21 while viewing the program list displayed on the display device 24. In other words, the recording / reproducing apparatus 1 receives an erasure instruction for erasing the erasure target information (S3). FIG. 10 is a diagram illustrating an example of a screen for selecting a program to be erased. In the example shown in FIG. 10, the four title numbers recorded on the two optical discs D2 and D4. Programs 3, 4, 6, and 7 are designated as deletion targets. The title No. Since 5 is a program (movie) recorded on a read-only optical disc, a column for displaying whether or not it is an erasure target cannot be selected.

  When receiving the erasure instruction, the controller 56 determines whether or not the optical disc 20 on which the erasure target information indicated by the erasure instruction is recorded is mounted on the recording / reproducing unit 8 at that time (S4).

  When the optical disk 20 is loaded (YES in S4), the controller 56 instructs the input / output signal processing unit 57 and the optical pickup control unit 58 to erase the file management information 221 of the information to be erased. . The input / output signal processing unit 57 and the optical pickup control unit 58 erase the file management information 221 of the erasure target information in accordance with the instruction (S5).

  Thereafter, the management table generation unit 53 deletes the management information related to the erasure target information from the disk recording information management table 41 and stores the updated disk recording information management table 41 in the auxiliary storage unit 4. Further, the management table generating unit 53 updates the value of the remaining recording capacity of the disk information management table 42 with the deletion of the information to be deleted (S6).

  When these processes are completed, the management table generating unit 53 outputs a command for updating the display list 44 to the display list generating unit 52.

  When receiving the above command, the display list generation unit 52 updates the display list 44 based on the updated disk recording information management table 41. That is, the display list generation unit 52 deletes management information (program title etc.) related to the deletion target information from the display list 44 (S7).

  On the other hand, when the optical disc 20 on which the deletion target information indicated by the deletion instruction is recorded is not attached to the recording / reproducing unit 8 (NO in S4), the controller 56 sets the deletion target via the management table generation unit 53. Information is recorded in the disk recording information management table 41 (temporary erasure state) (S8).

  FIG. 11B is a diagram showing an example of a disk recording information management table 41 in which erasure target setting information is recorded. As shown in FIG. When the programs 3, 4, 6, and 7 are designated as erasure targets, as shown in FIG. 11B, the erasure target setting information indicating that these programs are erasure targets is recorded in the disk recording information management table. 41. The erasure target setting information is shown as “target” in FIG. The title number of the program to be deleted. Is deleted, and a new title No. is assigned to the program not to be deleted. Is granted.

  The program to be erased is treated as a program that cannot be reproduced. Therefore, it can be said that the erasure target setting information is reproduction non-permission information indicating that reproduction of the program is not permitted.

  Thereafter, the management table generating unit 53 adds the capacity of the program to be deleted in the disk information management table 42 to the remaining capacity of the optical disk 20 on which the program is recorded (S9). That is, when a certain program is to be deleted, the management table generating unit 53 manages the remaining capacity of the optical disc 20 as being deleted even if the program is not deleted from the optical disc 20. FIG. 11A shows an example of the disc information management table 42 in which the remaining recording capacity is updated. In the disk information management table 42 shown in FIG. 11A, the disk No. is compared with the disk information management table 42 shown in FIG. The remaining recording capacity of D2 and D4 is updated.

  When these processes are completed, the management table generating unit 53 outputs a command for updating the display list 44 to the display list generating unit 52.

  Upon receiving the above command, the display list generating unit 52 updates the display list 44 based on the updated disk recording information management table 41 (S10). FIG. 12 is a schematic diagram illustrating an example of an updated program list. Title No. Since the programs 3, 4, 6, and 7 are designated as deletion targets, the deletion target programs are deleted from the program list as shown in FIG. Programs to which are assigned are listed.

  Thereafter, the controller 56 deletes the file management information 221 of the program to be deleted at a predetermined timing to be described later (S11).

  When the file management information 221 of the program to be erased is erased, the management table generating unit 53 erases the management information related to the program to be erased from the disk recording information management table 41 (S12). FIG. 13A is a diagram showing the disc information management table 42 in which the remaining recording capacity is updated in the above-described process (S9), and FIG. 13B is the disc recording information from which the management information of the erasure target information is deleted. It is a figure which shows the management table 41. FIG. In the example shown in FIG. The management information related to the programs recorded in D2 and D4 has been completely deleted from the disk recording information management table 41. With this process, a series of erasure processes is completed.

  Note that the display list generation unit 52 performs the process of erasing information related to the erasure target information from the display list 44 when an erasure instruction for erasing the erasure target information is input (that is, between S3 and S4). ) You may go.

(First example of erase timing)
Next, an example of the timing at which the file management information 221 of the program to be erased is erased from the optical disc 20 will be described with reference to FIG. FIG. 14 is a flowchart illustrating an example of a process for deleting the file management information of the information to be deleted.

  Here, an example will be described in which the file management information 221 of the program to be erased is erased from the optical disc 20a when the user inputs an instruction to reproduce information from the optical disc 20a on which the program to be erased is recorded.

  First, when a user inputs a playback instruction for the optical disc 20a, the controller 56 receives the playback instruction (S21).

  When receiving the reproduction instruction, the controller 56 outputs an instruction to load the optical disc 20a to the turntable control unit 59 and the optical pickup control unit 58. When receiving this instruction, the turntable control unit 59 controls the turntable moving unit 13 to rotate the turntable 12 and sets the optical disc 20 a as a reproduction target of the recording / reproducing unit 8. Further, as shown in FIGS. 5B and 5C, the optical pickup control unit 58 controls the position adjusting unit 11 to mount the optical disc 20a on the spindle motor 10 (S22).

  Further, the controller 56 determines whether there is a program recorded on the optical disc 20a and set as a deletion target by referring to the disc recording information management table 41 (S23).

  When a program set as an erasure target (program to be erased) is recorded on optical disk 20a (YES in S24), controller 56 erases via input / output signal processing unit 57 and optical pickup control unit 58. The file management information 221 of the target program is deleted (S25). When there are a plurality of deletion target programs recorded on the optical disc 20a, the file management information 221 corresponding to the plurality of deletion target programs may be deleted.

  Thereafter, the controller 56 commands the management table generation unit 53 to update the disk recording information management table 41.

  When receiving the command, the management table generating unit 53 deletes the management information related to the erasure target program from the disk recording information management table 41 (S26).

  When the update of the disk recording information management table 41 is completed, the controller 56 instructs the optical pickup control unit 58 to reproduce the program instructed to be reproduced. The optical pickup controller 58 reproduces the program recorded on the optical disc 20a by controlling the optical pickup 9 and the spindle motor 10 (S27).

  On the other hand, when the program set to be erased (program to be erased) is not recorded on optical disc 20a (NO in S24), controller 56 reproduces the program recorded on optical disc 20a in accordance with the user's instruction. (S27).

  Note that the file management information 221 of the erasure target program may be erased after the program instructed to be reproduced is reproduced, while the optical disk 20a on which the erasure target program is recorded is loaded in the recording / reproducing unit 8 and recorded. The file management information 221 of the program to be deleted may be deleted while the reproduction operation is not being performed. Note that the time when the recording / reproducing operation is not performed means that the optical pickup 9 is not recording a signal on the optical disc 20a or reproducing a signal. For example, in the case of a recording / reproducing apparatus equipped with a buffer memory, for example, by rotating an optical disc at high speed, pre-reading a reproduction signal, storing the information in the buffer memory, and sequentially reproducing the user, Despite watching the video reproduced from the optical disk on the display device, the optical pickup has a free time during which no signal is reproduced. The file management information 221 of the program to be erased may be erased using this free time. The same applies to recording, and in order to record a reserved program, erasing may be performed using the idle time in which the signal is recorded.

  Further, when the user inputs an instruction to record information on the optical disc 20a on which the program to be erased is recorded, the file management information 221 of the program to be erased may be erased from the optical disc 20a.

  However, when information is further recorded on the optical disc 20a having a small remaining recording capacity, it is preferable to delete the file management information 221 of the program to be erased before performing the recording. Since the file management information 221 can be erased in a very short time after the optical disk 20 is loaded, even if the file management information 221 is erased before the reproduction or recording operation, a time delay (waiting time) is caused to the user. There is little possibility of feeling.

  Details of the case where the user loads the optical disc 20a into the recording / playback unit 8 and records the file management information 221 of the program to be deleted will be described later in order to record the program for which the user has set the reserved recording. Further, as described above, even during the recording of the program, by rotating the disc at a high speed, it is possible to create a free time during which the optical pickup 9 is not recording a signal. The file management information 221 may be deleted using it.

(Second example of erase timing)
Next, another example of timing for erasing the file management information 221 of a program to be erased from the optical disc 20 will be described with reference to FIG. FIG. 15 is a flowchart showing another example of the process of deleting the file management information of the information to be deleted.

  Here, an example will be described in which the file management information 221 of the program to be erased is erased from the optical disc 20a when the main power supply 7 of the recording / reproducing apparatus 1 is set to OFF.

  The state in which the main power supply 7 is set to OFF is a so-called standby state in which recording and reproduction operations are not performed except for a recording (or reproduction) operation reserved by the user. In other words, when the main power supply 7 is OFF, recording and playback operations are not performed even if the user inputs a playback or recording instruction. In such a standby state, the main power supply 7 is not completely turned off, and power consumption is smaller than when the main power supply 7 is turned on.

  First, when the user inputs an instruction to turn off the main power supply 7, the controller 56 turns off the main power supply 7 (S31).

  Thereafter, the controller 56 determines whether or not there is at least one program set as an erasure target (erasure target program) by referring to the disk recording information management table 41 (S32).

  If there is at least one program to be erased (YES in S33), the controller 56 determines that the time t1 required for erasing the file management information 221 corresponding to one of the programs to be erased and the timer 6 are The time t2 from the current time shown to the start time of the next recording reservation or reproduction reservation recorded in the reservation list 45 is compared (S34). That is, the controller 56 determines whether or not the file management information 221 of a certain erasure target program can be erased before the next recording (or reproduction) reservation operation recorded in the reservation list 45 is started.

  When t2 is larger than t1 (that is, when file management information 221 of the program to be erased can be erased by the start time of the next recording (or playback) reservation) (YES in S35), controller 56 Then, the optical disc 20 on which the program to be erased is recorded is loaded into the recording / reproducing unit 8 via the optical pickup control unit 58 and the turntable control unit 59 (S36).

  Thereafter, the controller 56 erases the file management information 221 of the program to be erased via the input / output signal processing unit 57 and the optical pickup control unit 58 (S37).

  Subsequently, the controller 56 commands the management table generation unit 53 to update the disk recording information management table 41.

  When receiving the command, the management table generating unit 53 deletes the management information related to the erasure target program from the disk recording information management table 41 (S38).

  Thereafter, the controller 56 determines whether there is any other program to be erased (return to S33).

  On the other hand, if t2 is smaller than t1, that is, if file management information 221 of the program to be erased cannot be erased by the start time of the next recording (or playback) reservation (NO in S35), controller 56 Is postponed to delete the file management information 221 until the recording (or playback) reservation indicated by the reservation list 45 ends, and is recorded in the reservation list 45 after the recording (or playback) reservation ends (YES in S39). It is determined whether the file management information 221 of the program to be erased can be erased before the next recording (or playback) reservation operation is started (return to S34).

  On the other hand, when there is no program to be erased (NO in S33), controller 56 maintains a standby state.

  Note that the above description is for the case where the main power supply 7 is set to OFF. However, the recording operation according to the recording reservation or the reproduction operation according to the reproduction reservation can be performed even when the main power supply 7 is ON. It may be. In this case, the process described as the second example can be performed even when the main power supply 7 is ON. That is, regardless of whether the main power supply 7 of the recording / reproducing apparatus 1 is ON or OFF, the controller 56 does not wait until the next recording (or reproduction) reservation operation recorded in the reservation list 45 is started. It is determined whether the file management information 221 of a certain erasure target program can be erased (whether there is free time), and when it is determined that erasure is possible (there is free time), the file management information of the erasure target program 221 may be deleted.

  Here, the controller 56 determines that there is a free time and starts an erasing operation for erasing the file management information 221 of the program to be erased, but the user gives an operation instruction (for example, a recording instruction) while the main power supply 7 is ON. ) Or when the user inputs an operation instruction after turning the main power source 7 from OFF to ON. In this case, the controller 56 gives priority to the erasing operation and performs the operation according to the operation instruction after the erasing operation is completed, or stops (or interrupts) the erasing operation and performs the operation according to the operation instruction. Either priority should be given.

  More specifically, when the optical disk 20 is loaded as an erasing operation (when a mechanical loading operation is performed, an operation of reading information on the optical disk 20 after the optical disk 20 is mounted on the recording / reproducing unit 8) In this case, the loading operation of the optical disc 20 may be stopped and the optical disc 20 designated by the user may be loaded.

  As the erasing operation, when the erasure target information is being erased, it is preferable to load the optical disc 20 designated by the user after the erasure is completed. The reason is that if the erasing operation is not completed completely, a reading error occurs in the next reproducing operation of the optical disc 20.

  As an erasing operation, even when the optical disc 20 in which erasure target information has been erased is being removed (removed) from the recording / reproducing unit 8, the optical disc 20 designated by the user is loaded after the removal is completed.

  When the user turns the main power supply 7 from OFF to ON, the controller 56 may consider the operation to turn on the main power supply 7 as the operation instruction and interrupt the erasing operation as described above.

(Third example of erase timing)
Next, when an instruction to take out the optical disc 20 on which the program to be erased is input before erasing the file management information 221 of the program to be erased from the optical disc 20, the file management information of the program to be erased is input. A process flow for deleting 221 will be described with reference to FIG. FIG. 16 is a flowchart showing still another example of the process of deleting the file management information of the deletion target information.

  First, when the user inputs an instruction to eject the optical disc 20a to the recording / reproducing apparatus 1, the controller 56 receives the instruction (S41).

  The controller 56 determines whether or not the erasure target program is recorded on the optical disc 20a by referring to the disc recording information management table 41 (S42).

  When the program to be erased is recorded on the optical disc 20a (YES in S43), the controller 56 loads the optical disc 20a into the recording / reproducing unit 8 via the optical pickup control unit 58 and the turntable control unit 59 (S44). Then, the file management information 221 of the program to be erased recorded on the optical disc 20a is erased via the input / output signal processor 57 and the optical pickup controller 58 (S45).

  At this time, the controller 56 instructs the display control unit 54 to display that it takes time to take out the optical disk 20a.

  When receiving the instruction, the display control unit 54 causes the display device 24 to display a message indicating that it takes time to remove the optical disc 20a (S46). The message is, for example, “Information is being erased” as a message indicating the operation status of the device even if the user does not know the processing content “Please wait for a while” as a message to prompt the user to wait. The processing content may be understood by the user.

  When the file management information 221 has been erased, the controller 56 commands the management table generation unit 53 to update the disk recording information management table 41.

  When receiving the command, the management table generating unit 53 deletes the management information related to the erasure target program from the disk recording information management table 41 (S47).

  Thereafter, the controller 56 ejects the optical disc 20a through the turntable control unit 59 (S48).

  On the other hand, when the erasure target program is not recorded on optical disc 20a (NO in S43), controller 56 ejects optical disc 20a through turntable control unit 59 (S48).

  As described above, by deleting the file management information 221 of the erasure target program before the optical disc 20 in which the erasure target program is recorded is taken out, the program that the user intends to delete can be reproduced by other playback. It can be prevented from being played back by the device.

  In addition, as described above, a message is displayed to the user during an operation related to erasure of the file management information 221 of the program to be erased after an instruction to eject the optical disc 20a is input. In contrast to the fact that it takes more time than the ejecting operation of the optical disc 20, the possibility that the user is confused can be reduced.

(Fourth example of erase timing)
Another example of the timing for deleting the file management information 221 of the program to be deleted from the optical disc 20 will be described.

  When the controller 56 obtains an erasure instruction for erasing the file management information 221 of all programs to be erased from the user, the controller 56 stores the file management information 221 of all programs to be erased at that time. It may be erased.

  When a plurality of erasure target programs are recorded on the plurality of optical discs 20, the controller 56 sequentially attaches all the optical discs 20 on which the erasure target programs are recorded to the recording / reproducing unit 8 and the erasure target programs. The file management information 221 is deleted.

  Since the information on the program to be erased has been deleted from the program list regardless of whether it has actually been erased, the user can decide which program has been temporarily erased. It is not possible to know whether it is in a state that has not been done. Therefore, the above-described operation is not an operation for erasing a specific program, but an operation for erasing all programs in a temporary erasure state.

  If an erasure instruction for erasing all temporarily erased programs has been input, but there is no program in the temporarily erased state, the recording / reproducing apparatus 1 displays a message to that effect on the display device 24. This may be notified to the user.

  In addition, the display list generating unit 52 may generate a list of programs that are temporarily deleted (temporarily deleted program list), and the display control unit 54 may display the temporarily deleted program list on the display device 24. . The temporary deletion program list (temporary deletion information list) may be incorporated in the display list 44 or may be generated separately from the display list 44.

  In this way, when displaying the temporary deletion program list, the user can input an deletion instruction to delete a specific program among the programs in the temporary deletion state. Therefore, in the above-described “operation instruction that the optical disc 20 on which the deletion target information is recorded is an operation target”, at least a part of the programs to be deleted or the file management information 221 thereof is deleted. An erasure instruction is also included.

(Modification example of optical disk storage and exchange mechanism)
The storage unit for storing the optical disc 20 and the mechanism for exchanging the optical disc 20 to be recorded / reproduced by the recording / reproducing unit 8 are not limited to the turntable 12 described above, and any mechanism may be used.

  FIG. 17 is a diagram illustrating a modification example of a storage unit that stores the optical disc 20. For example, the optical disk 20 may be stored in a cartridge 70 including a plurality of trays 71 as shown in FIG.

  A plurality of trays 71 are stacked and stored in the cartridge 70 in a state in which the trays 71 can slide out of the cartridge 70 by sliding on guide rails (not shown). Tray NO.
