[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording device and a reservation recording method.

[0002]

2. Description of the Related Art With the spread of MDs (minidiscs),
Recording / reproducing apparatus (recording apparatus) represented by MD recorders and the like
Has spread as one of the popular audio devices. Such a recording / reproducing apparatus stores, for example, music data received by an FM tuner included therein, music data input from an external input terminal, or the like on a disc (recordable M
D) and can be played back. Also,
The recording / reproducing apparatus generally has a reserved recording function,
At the set recording start time, the music data can be automatically recorded (recorded). For example, when the recording / reproducing apparatus acquires information for setting reserved recording via a predetermined operation unit, the recording / reproducing apparatus enters a reserved recording execution standby state. And
At the recording start time, the music data received by the FM tuner or the like is recorded on the disc (recording starts), and again.
When the recording end time comes, the recording is automatically ended.

Such a recording / reproducing apparatus (MD recorder)
Among them, a model called a double MD type has been commercialized. A recording / reproducing device of this type is
A plurality of (two) disks can be loaded, and recording / playback, reserved recording, and the like can be performed on each disk. A recording / reproducing apparatus capable of loading such a plurality of discs (MDs) will be described with reference to FIG. Figure 4
FIG. 9 is a block diagram showing an example of a conventional recording / reproducing apparatus. As shown in the figure, this recording / reproducing apparatus has two recording / reproducing units 91a and 91b, an operation unit 92, and a storage unit 93.
And a controller 94 and a display unit 95.

The recording / reproducing units 91a and 91b are controlled by the controller 94, respectively, record music data on the disks Da and Db, and reproduce music data from the disks Da and Db. Specifically, the recording / reproducing units 91a, 91
b indicates the analog music signal to be recorded during recording.
After performing D / D conversion, compression, addition of interleave and error correction code, and EFM modulation to generate music data, the music data is recorded in the unrecorded areas (data areas) of the disks Da and Db. Also, at the time of reproduction, the music data of the reproduction target track in the data area is read to
M demodulation, deinterleave and error correction, expansion, etc. are performed, and D / A conversion is performed to generate an analog music signal, which is supplied to a predetermined speaker.

The operation unit 92 is composed of a plurality of key switches arranged on the front surface of the apparatus, and reservation information (reservation recording start time, reservation recording start time,
Reserved recording end time, recording source, recording mode, etc.)
Instruction information for reproduction, recording, stop, pause, etc. is generated and supplied to the controller 94. The storage unit 93 is
It is composed of a non-volatile memory or the like, and stores reservation information and numerical values necessary for processing executed by the controller 94.

The controller 94 is composed of a one-chip microcomputer and controls the entire apparatus. Specifically, the controller 94 acquires the reservation information that is the setting content of the reservation recording according to the information input by the user via the operation unit 92, and stores the reservation information in the storage unit 93. Then, according to the reservation information stored in the storage unit 93, at the reserved recording start time, the recording / reproducing unit 91a and the like are controlled to record the music data supplied from the target recording source on the recordable disc Da or the like. . The display unit 95 displays information indicating the operation status of the recording / reproducing apparatus, and displays information that assists the user who operates the operation unit 92 to input the reservation information when setting the reserved recording.

The operation of the recording / reproducing apparatus having such a configuration will be described below by taking the reserved recording process as an example. Figure 5
6 is a flowchart for explaining a reserved recording process executed by the controller 94. It should be noted that, before execution of this reserved recording process, it is assumed that the storage unit 93 has stored therein reservation information that is the setting content of the reserved recording.
It is assumed that the main power supply of the recording / reproducing device is off. Then, this processing is automatically started, for example, a few minutes before the start time of the reserved recording.

First, the controller 94 turns on the main power source of the recording / reproducing apparatus (step S81), and switches the control target to the recording / reproducing section 91a (step S82). The controller 94 determines the presence / absence of a recordable disc in the switched recording / reproducing section (recording / reproducing section 91a in the first case, recording / reproducing section 91b in the case after the processing of step S85) (step S83). ). It should be noted that the recordable disc referred to here is a disc whose erroneous erasure prevention knob is set to “recordable”. In other words, the controller 94 determines that the disc is not recordable if the disc is not loaded and if the erroneous erasure prevention knob is set to "record prohibited".

When the controller 94 determines that there is no recordable disc, the controller 94 determines whether or not the control target has been switched to the recording / reproducing unit 91b (step S8).
4). In other words, following the first recording / playback unit 91a, 2
It is also determined whether or not the disc is checked for the second recording / reproducing unit 91b. When the controller 94 determines that the recording / playback unit 91b has been switched to,
Since there is no recordable disc in both the recording / reproducing units 91a and 91b, the process proceeds to step S94 described later. On the other hand, when it is determined that the recording / reproducing unit 91b has not been switched, the controller 94 switches the control target to the recording / reproducing unit 91b (step S85), and returns the process to step S83.

When it is determined in step S83 that a recordable disc is loaded, the controller 94
The recording start address is read (step S86), and the recording start address is searched (step S87). That is, the controller 94 uses the recordable disc to UT
The OC (User Table Of Contents) information is acquired, and this U
The pointer of the recording start address is read from the TOC information. Then, the corresponding recording start address in the data area of the disc is searched. The controller 94
According to the reservation information stored in the storage unit 93, the selector (not shown) is switched to the target recording source (tuner, AUX, etc.) (step S88), and the control target recording / reproducing unit (recording / reproducing unit 91a or 91b). Is set to a recording standby state (recording pause state or the like) (step S89). Then, the controller 94 waits for execution of subsequent processing until the reserved recording start time comes (step S90).

At the reserved recording start time, the controller 94 starts recording (step S91). That is, the controller 94 operates the recording / reproducing unit in the recording standby state to record the music data from the target recording source on the disc. Then, the controller 94 maintains the recording operation until the reserved recording end time comes (step S92). At the scheduled recording end time,
The controller 94 ends the recording (step S9
3) The main power supply is turned off (step S94).

By such a reserved recording process, the recording / reproducing apparatus shown in FIG. 4 has two recording / reproducing units 91a and 91b.
The music data can be reserved and recorded on either the disc Da or the disc Da by properly switching the control.

[0013]

However, in the conventional recording / reproducing apparatus described above, the reserved recording process shown in FIG. 5 only externally determines that the disc is a recordable disc. Even if the reserved recording operation starts,
Recording was not always done. This means that even if the disc is set with the erroneous erasure prevention knob set to "recordable", the inappropriate management information (U
This is because the music data cannot be recorded in the state where the TOC information) is recorded. That is,
In the reserved recording process shown in FIG. 5, the UTOC information and the recording start address cannot be read (step S8).
6) Also, it is not possible to retrieve the recording start address by reading out the inconsistent address (step S87).
In this case, the controller 94 detects an unexpected error and forcibly stops the processing (or forcibly shifts to the error processing). Therefore, the subsequent recording process (step S91 etc.) is not executed, and as a result, the music data is not recorded on any disc.

Such an inconvenience can occur even when inappropriate management information is recorded only on one disk and normal management information is recorded on the other disk. That is, one disk (disk with improper management information)
When it is externally determined that the disc is a recordable disc, the controller 94 attempts to start reserved recording for one disc. Then, an unexpected error is detected, and the process ends without recording. In this case, if the reserved recording is started on the other disc, the music data can be recorded. That is, in the conventional recording / reproducing apparatus as shown in FIG. 4, although the plurality of discs can be loaded, the discs capable of recording are discriminated externally, and thus the originally reserved recording can be normally performed. There were times when I couldn't let it go.

The recording / reproducing sections 1a and 1b are composed of, for example, a drive section for rotationally driving the disks Da and Db to be recorded / reproduced, a pickup for irradiating the disks Da and Db with laser light, and a pickup. A magnetic head that magnetizes a portion irradiated with laser light and a signal processing unit that performs signal processing of music data to be written by the magnetic head are included. Specifically, the recording / reproducing section 1a, 1
When recording, analog audio signals to be recorded are A / D-converted at the time of recording, compression, interleaving and addition of error correction code, EFM modulation, etc. are performed to generate music data, and then the discs Da and Db are recorded. The data is recorded in the unrecorded area (data area). Further, at the time of reproduction, the music data of the reproduction target track in the data area is read, EFM demodulation, deinterleave and error correction, expansion, etc. are performed, and D / A conversion is performed to generate an analog audio signal.

The tuner unit 2 comprises a predetermined AM / FM tuner or the like controlled by the control unit 5, tunes to a predetermined frequency, and receives an audio signal of a broadcast program transmitted from a corresponding broadcasting station. The tuner unit 2 supplies the received audio signal to the input selector 3.

The input selector 3 inputs audio signals respectively supplied from the tuner unit 2 and a recording source such as AUX (external input). And the control unit 5
Control is performed to select one of the audio signals, and the selected audio signal is supplied to the recording / reproducing units 1a and 1b. The input selector 3 also supplies the selected audio signal to an amplifier circuit, a speaker and the like (not shown).

The storage unit 4 is composed of a non-volatile memory or the like, and stores the reservation information which is the setting content of the reserved recording and the numerical values necessary for the processing executed by the control unit 5. For example, the storage unit 4 stores reservation information including a reserved recording start time, a reserved recording end time, a recording source, and a recording mode.

The control unit 5 includes a CPU (Central Processing).
Unit), ROM (Read Only Memory), etc., and is composed of a one-chip microcomputer and controls the entire recording / reproducing apparatus. In addition, the control unit 5 includes a timer 5 that measures the current time and the like.
1 is provided. Specifically, the control unit 5 controls the recording / reproducing units 1a, 1b, etc. to record the music data on the target discs (discs Da, Db), and the music data recorded on the discs Da, Db. Reproduce. Further, when the control unit 5 acquires the reservation information which is the setting content of the reservation recording via the operation unit 6, the control unit 5 stores the reservation information in the storage unit 4. Then, the current time measured by the timer 51 is several minutes before the reservation recording start time of the reservation information (for example,
2 minutes before), the recording / reproducing sections 1a and 1b are controlled to discriminate the discs (discs Da and Db) which can be recorded not only externally but also substantially. Eventually, at the reservation start time, the music data is recorded on the disc that has been discriminated.

The operation unit 6 is composed of a plurality of key switches arranged on the front surface of the apparatus, and reservation information (reservation recording start time, reservation recording end time, recording source) which is the setting contents of the reservation recording according to the user's operation. , And recording mode etc.)
Also, instruction information such as reproduction, recording, stop and pause is generated and supplied to the control unit 5.

The display section 7 is composed of a fluorescent display tube, a liquid crystal display panel or the like, and displays information indicating the operation status of the recording / reproducing apparatus. For example, the display unit 7 displays information to assist the user who operates the operation unit 5 to input reservation information when setting the reservation recording.

The operation of the recording / reproducing apparatus according to this embodiment will be described below with reference to FIG. This Figure 2
6 is a flowchart for explaining a reserved recording process executed by a control unit 5 of the recording / reproducing apparatus. It should be noted that, prior to the execution of this reserved recording process, it is assumed that the storage unit 4 stores the reservation information that is the setting content of the reserved recording.
It is assumed that the main power supply of the recording / reproducing device is off. Then, this processing is automatically started, for example, a few minutes before the start time of the reserved recording.

First, the control section 5 turns on the main power source of the recording / reproducing apparatus (step S11), and switches the control target to the recording / reproducing section 1a (step S12). That is, the control unit 5 makes the recording / reproducing units 1a and 1b, the tuner unit 2, and the like operable, so that the recording / reproducing unit 1a is first controlled after the main power of the device is turned on.

The control unit 5 controls the recording / reproducing unit (if it is the first recording / reproducing unit 1a, or step S17).
After the processing of (1), the recording / reproducing unit 1b) externally determines the presence / absence of a recordable disc (step S).
13). The external determination referred to here is whether or not a disc is loaded and whether or not the erroneous erasure prevention knob is set to "recordable". That is, the control unit 5
If the loaded disc's accidental erasure prevention knob is "recordable", it is externally determined to be a recordable disc. In addition, if the disc is not loaded, accidental erasure prevention If the knob is "recording prohibited",
The disc is not recordable.

When the control unit 5 determines that the disc is not a recordable disc, the control unit 5 advances the process to step S16 described later.
On the other hand, when it is externally determined that the disc is a recordable disc, the control unit 5 reads out the UTOC information (step S
14). That is, the UTOC information, which is the management information of the disks (disks Da and Db), is read from the disk that is externally determined to be recordable.

The control section 5 determines whether or not the read UTOC information is normal (step S15). Specifically, the control unit 5 inspects whether the UTOC information is inconsistent, the pointer of the recording start address is inconsistent, and the like.
It is determined whether or not the UTOC information is normal. That is,
The control unit 5 substantially determines whether the disc is a recordable disc based on the read UTOC information. Note that U
Even when the TOC information itself cannot be read from the management information area of the disc, the control unit 5 determines that the UTOC information is not normal.

When the control unit 5 determines that the UTOC information is not normal, it determines whether the recording / reproducing unit 1b has been switched (step S16). That is, after the first recording / reproducing unit 1a, it is determined whether or not the second recording / reproducing unit 1b has also checked the disc. When the control unit 5 determines that the recording / reproducing unit 1b has been switched to, both the recording / reproducing units 1a and 1b
Since there was no external or practically recordable disc,
The process proceeds to step S26 described below. On the other hand, record
If it is determined that the reproduction unit 1b has not been switched, the control unit 5 switches the control target to the recording / reproduction unit 1b (step S17) and returns the process to step S13.

When it is determined in step S15 that the UTOC information is normal, the control section 5 reads the recording start address (step S18) and searches for the recording start address (step S19). That is, the control unit 5 reads the pointer of the recording start address from the UTOC information of the virtually recordable disc. Then, the corresponding recording start address in the data area of the disc is searched. The control unit 5 follows the reservation information stored in the storage unit 4, and the target recording source (tuner 2, AUX, etc.)
The input selector 3 is switched to (step S20), and the control target recording / reproducing unit (recording / reproducing unit 1a or 1b) is
A recording standby state (recording pause state or the like) is set (step S21). Then, the control unit 5 waits for execution of subsequent processing until the reserved recording start time comes (step S2).
2).

At the reserved recording start time, the control unit 5
Recording is started (step S23). That is, the control unit 5 operates the recording / reproducing unit in the recording standby state to record the music data from the target recording source on the disc. Then, the control unit 5 maintains the recording operation until the reserved recording end time comes (step S24). At the reserved recording end time, the control unit 5 ends the recording (step S25) and turns off the main power source (step S25).
26).

As described above, by the reserved recording process shown in FIG. 2, it is substantially determined that the disc can be recorded according to the UTOC information. Therefore, reserved recording is not performed on a disc that cannot be recorded. In other words, a recording / reproducing device (recording device) capable of loading a plurality of discs substantially discriminates the recordable discs. Therefore, if a recordable disc is included in the plurality of discs, a reservation is made. Recording is done normally. As a result, reservation recording such as reservation recording can be appropriately performed.

In the above-described embodiment, the reserved recording is performed on the disc which is determined to be substantially recordable in the reserved recording process shown in FIG. 2, but the remaining recording time of the disc (recording is possible. The reserved recording may be performed by further considering the remaining time. Hereinafter, another embodiment of the present invention will be briefly described with reference to FIG. FIG. 3 is a flowchart for explaining a reservation recording process according to another embodiment. In addition, the reservation recording process shown in FIG.
This is obtained by adding step S31 and step S32 to the reservation recording process shown in FIG.

That is, similarly to the reserved recording process shown in FIG. 2, the control unit 5 reads the UTOC information from the disc that is externally determined to be recordable (step S14), and determines that the read UTOC information is normal. If so (step S15), the recording start address is read (step S18).

Then, the control section 5 obtains the remaining recordable time on the disc (step S31). The control unit 5 determines whether or not the obtained remaining time is sufficient (step S32). That is, the control unit 5 controls the storage unit 4
The time required for reserved recording (required recording time) is obtained from the reserved recording start time and reserved recording end time of the reservation information stored in (1). Then, the required recording time and the remaining recording time are compared to determine whether or not the remaining recording time of the disc is sufficient.

If the control section 5 determines that it is not sufficient, the control section 5 advances the processing to step S16 or the like to switch the recording / reproducing section to be controlled. On the other hand, if it is determined that the remaining recording time is sufficient, the control unit 5 advances the processing to step S19 or the like, searches for the recording start address, etc., and then enters the recording standby state (step S21). Then, at the reserved recording start time, the control unit 5 starts recording (step S2).
3) When the reserved recording end time comes, recording is ended (step S25).

As described above, by the reserved recording process shown in FIG. 3, after it is substantially determined that the disc is recordable, the remaining recording time of the disc is compared with the required recording time, and the reserved recording is performed. It is also determined whether the process is completed normally. Also in this case, reservation recording such as reservation recording can be appropriately performed.

In the above-described embodiment, the recording / reproducing apparatus for recording the music data on the MD in advance has been described as an example, but the recording medium to be recorded is not limited to the MD and is arbitrary. For example, CD-R / W, CD-RAM, DVD-R
It may be a recording medium that manages the recording data by management information such as / W and DVD-RAM. The data to be recorded is not limited to music data, but may be image data, moving image data, or the like.

In the above embodiment, a recording / reproducing apparatus capable of mounting two disks (recording media) has been described as an example, but the number of recording media to be mounted is arbitrary as long as it is two or more. Further, the recording media to be mounted do not have to be the same, and a plurality of types of recording media may be mounted, and the music data or the like may be recorded on any type of recording medium that can be recorded substantially.

In the above-described embodiment, it is determined whether or not the disc is substantially recordable when the reserved recording is executed (during the reserved recording process). However, when the reserved recording is set, the disc is not recorded. It may be determined whether or not recording is substantially possible. Then, the determination result may be displayed on the display unit 7 or may be output as voice or the like from a predetermined speaker. Further, information specifying a recordable disc may be stored in the storage unit 4 by including it in the reservation information so that it can be used when executing the reserved recording. Further, in response to a simple pressing operation of the recording key included in the operation unit 6, it may be determined whether or not the disc is substantially recordable.

In the above-described embodiment, the case where one recording / reproducing apparatus is provided with a plurality of recording / reproducing sections (recording / reproducing sections 1a, 1b) has been described, but a predetermined control device is used for other recording / reproducing sections. It is also applicable as appropriate when controlling a plurality of recording devices and the like.
