DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk recording / reproducing apparatus, and can be applied to, for example, an audio apparatus in which a compact disk player and a magneto-optical disk apparatus are integrated.

[0002]

2. Description of the Related Art Conventionally, there is a portable audio device in which a compact disc player and a tape recorder are integrated, and music reproduced by the compact disc player can be directly recorded by a tape recorder. .

As a result, a user can easily dub a compact disc as necessary, and can carry this device to reproduce various recording media.

[0004]

In this type of audio equipment, if a magneto-optical disk drive can be integrated in place of the tape recorder, it is considered that usability can be further improved.

That is, in a magneto-optical disk drive,
By being able to select a desired music piece at random, there is a feature that is easier to use than a tape recorder. Further, by being able to record and reproduce a digital audio signal, it is possible to record and reproduce a high-quality audio signal.

However, in the case of a compact disc player, if the compact disc is scratched, there is a possibility that the same spot will be reproduced many times over at the scratched portion. As a result, in the magneto-optical disc device, However, there is also a problem that unless the user interrupts dubbing by his / her own operation, the dubbing of the audio signal of the same portion reproduced by the compact disc player is continued as it is.

For this reason, even if the compact disc player reproduces the same portion over and over due to a scratch on the compact disc, it corresponds to the scratch on the magneto-optical disc device. If it is possible to skip dubbing a song and continue dubbing from the beginning of the next song, it is possible to save the user's labor by that much compared to the case where the user finishes dubbing and redo the dubbing again, and it is compact. Since it is possible to reliably dub a song other than the song corresponding to the scratched portion on the disc, it is considered that the benefit is large for the user as a result.

Further, if it is possible to notify the user of the number of music corresponding to the scratched portion on the compact disc, it is considered that usability can be further improved for the user.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and it is an object of the present invention to propose a disk recording / reproducing apparatus which can improve the usability of a user.

[0010]

According to the present invention, there is provided a disk recording / reproducing apparatus for dubbing an information signal S4 reproduced from a first disk-shaped recording medium 10 to a second disk-shaped recording medium 50 according to the present invention. In the device 1,
Reproducing means 6 for reproducing the information signal S4 from the first disc-shaped recording medium 10, recording means 8 for recording the information signal S4 reproduced from the reproducing means 6 on the second disc-shaped recording medium 50, and reproducing means 6 Detecting means 16 for detecting that the continuous reproduction of the information signal S4 from the CPU has been interrupted by disturbance
When the detecting means determines that the continuous reproduction of the information signal S4 from the reproducing means 6 has been interrupted by a disturbance, a determining means 82 for determining whether or not a period for repeatedly reproducing the same portion is longer than a predetermined time. If the determination unit 82 determines that the reproducing unit 6 repeatedly reproduces the same location for a predetermined time or more, the information signal S4 corresponding to the same location repeatedly reproduced is transmitted to the second disk-shaped recording medium 50. Control means 32 and 82 are provided to control the recording operation to be interrupted and to transfer the reproducing means 6 away from the same place.

As a result, in the disc recording / reproducing apparatus 1, if the reproducing means 6 repeatedly reproduces the same portion for a predetermined time or more due to a scratch on the first disc-shaped recording medium 10 during dubbing, the second By interrupting the recording operation on the disc-shaped recording medium 50 and moving the reproducing means 6 away from the same location, the output of the information signal repeatedly reproduced at the same location is muted and, if necessary, The next predetermined portion based on the same portion can be reproduced, and thus the user's labor can be saved by that much as compared to the case where the user ends dubbing and redoes again.

In the present invention, the second disk-shaped recording medium 50 has a management area for managing character information corresponding to the recorded information signal S4, and is recorded on the second disk-shaped recording medium 50. First disk-shaped recording medium 10
Signal S corresponding to the same portion repeatedly reproduced from
In correspondence with No. 4, character information indicating that recording was interrupted is recorded in the management area.

As a result, in the disc recording / reproducing apparatus 1, at the time of dubbing, the character information indicating that the recording has been interrupted is recorded in the management area of the second disc-shaped recording medium 50. Thus, it is possible to notify the user that the song corresponding to the scratched portion on the first disk-shaped recording medium 10 could not be dubbed, thereby improving the usability of the user.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings.

(1) Appearance Configuration In FIG. 1, reference numeral 1 denotes a portable audio apparatus as a whole. Speakers 2 and 4 are arranged on the left and right, and a compact disc player section 6 and the like are arranged in the center.

That is, in the audio device 1, the magneto-optical disk unit 8 is arranged adjacent to the compact disk player unit 6 so that the audio signal reproduced by the compact disk player unit 6 can be dubbed by the magneto-optical disk unit 8. The reproduction signals of the compact disk player unit 6 and the magneto-optical disk unit 8 can be monitored via the speakers 2 and 4.

On the other hand, on the front side of the audio apparatus 1, there are arranged the controls of the compact disc player section 6 and the magneto-optical disc section 8 and a display section for displaying an operation mode and the like. It is made to be able to confirm.

(2) Compact Disc Player Section As shown in FIG. 2, the compact disc player section 6
Drives the compact disk 10 by the spindle motor 12, processes the reproduction signal S1 output from the optical pickup 14 in this state, and reproduces the compact disk 10.

That is, the compact disk player section 6
, The RF signal processing circuit 16
After amplifying the reproduction signal S1 of No. 4, the signal is converted into a binary signal and output to the signal processing circuit 18, and the tracking error signal TE and the focus error signal FE are detected and output to the servo circuit 20.

Thus, in the servo circuit 20, the optical pickup 14 is driven via the driver circuit 22,
Tracking control and focus control are performed.

Further, the RF signal processing circuit 16 detects the flaw of the compact disk 10 by detecting the signal level of the reproduction signal S1, and outputs the detection result to the flaw detection signal S1.
Output as 3.

Here, as shown in FIG. 3, if the compact disc 10 is damaged,
If a track jump occurs, it becomes impossible for this kind of compact disc player to correct errors in audio data correctly, and in some cases, it becomes difficult to demodulate the audio data.

In this case, the audio signal output from the compact disc player is in a so-called skipped state which is output intermittently.

In the reproduced signal S1 output from the optical pickup 14 in this skipped state, the entire amplitude sharply falls at the skipped portion (FIG. 3 (A)), and the focus error signal FE is accordingly generated. (FIG. 3B) and the tracking error signal TE (FIG. 3C) also change greatly.

Thus, the RF signal processing circuit 16 detects a change in the amplitude of the reproduced signal S1, the focus error signal FE, and the tracking error signal TE, thereby obtaining a flaw detection signal S3 whose signal level rises at the flaw.
Generate

Incidentally, when the optical pickup 14 jumps a track due to an external impact, the reproduction signal S1, the focus error signal FE, and the tracking error signal TE change similarly to the case of the scratch.

However, the change of the reproduction signal S1 is different between the case of a flaw and the case of an external impact. In the case of this embodiment, a pass band is passed through a band-pass filter circuit having a frequency of 30 to 300 [Hz]. By detecting the change in the amplitude of the reproduction signal S1, the change in the focus error signal FE, and the change in the tracking error signal TE, it is possible to reliably detect only a flaw.

The signal processing circuit 18 is an RF signal processing circuit 1
The binary signal output from 6 is subjected to signal processing, thereby demodulating audio data, performing error correction processing and deinterleaving processing, and outputting the result.

The memory controller 24 includes the memory circuit 2
6, the memory circuit 26 is used as a buffer memory for audio data.

That is, the memory circuit 26 is capable of storing about three seconds of audio data in terms of an audio signal, and the memory controller 24 sequentially stores the audio data output from the signal processing circuit 18 in the memory circuit. 26, and read out and output at a predetermined timing.

Thus, in the compact disk player section 6, for example, a skipped portion is reproduced again using the period until the audio data once stored in the memory circuit 26 is output.

Digital-to-analog conversion circuit (D / A) 2
8 converts the audio data output from the memory controller 24 into an analog signal, and outputs the analog signal via the output circuit 30.

Thus, in the audio device 1,
The audio signal S4 output from the output circuit 30 can be output to the magneto-optical disk unit 8 for dubbing, and can be output from the speakers 2 and 4 as needed.

In the compact disk player section 6, the control circuit 32 controls the entire operation. That is, the control circuit 32 outputs control data to each circuit block in response to the operation of the operation element, thereby switching the operation of the entire compact disc player section 6, and further switching the display of the display section 34 as necessary. .

Further, the control circuit 32 detects a sound skip accident due to an external impact, and executes a recovery process based on the detection result. That is, in the compact disc player section 6, the spindle motor 12 is fixed to the chassis via the predetermined insulator 36, so that the frequency of sound skipping due to an external impact is reduced.

Further, in the compact disk player section 6, an acceleration sensor (G sensor) 38 is disposed on the same base as the spindle motor 12, and an output signal of the acceleration sensor 38 is output to a band-pass filter circuit (BPF) 4
Output to 0.

The band-pass filter circuit 40 extracts a signal component of an external impact from the output signal of the acceleration sensor 38, and then obtains a comparison result between a predetermined reference level and a comparison circuit (COM) 42. When an external shock equal to or more than a predetermined value is applied to the compact disc 10, the signal output is a vibration detection signal S5 whose signal level rises.

As a result, the control circuit 32 outputs the flaw detection signal S
An accident during reproduction is detected with reference to the vibration detection signal 3 and the vibration detection signal S5, and a detection result D1 is output to the magneto-optical disk unit 8.

Further, in this embodiment, when an accident is detected in the compact disk player section 6, the control circuit 32 executes a recovery process for this accident, whereas the control circuit 32 performs recording in the magneto-optical disk section 8 in the same manner. When the accident occurs, the control data D output from the magneto-optical disk unit 8
2 to switch the overall operation, whereby the audio signal can be reliably recorded and reproduced as a whole device.

(3) Magneto-optical disk unit As shown in FIG. 4, the magneto-optical disk unit 8 includes an audio signal S output from the compact disk player unit 6.
4 is converted into a digital signal and recorded on the magneto-optical disk 50, and the magneto-optical disk 50 is reproduced in response to the operation of the operation element.

That is, in the magneto-optical disk section 8,
The magneto-optical disk 50 is driven to rotate by the spindle motor 52, and in this state, the optical pickup 54 and the modulation coil 56
Is driven to record and reproduce desired information.

In the magneto-optical disk section 8, the reproduced signal S 4 output from the compact disk player section 6 is converted into a digital signal by an analog-to-digital converter (A / D) 58 and then input to a signal processing circuit 60.

Here, the signal processing circuit 60 compresses the digital audio signal and outputs it. The memory controller 62 uses the memory circuit 64 as a buffer memory for audio data by controlling the input and output of the memory circuit 64.

That is, the memory circuit 64 is capable of storing about three seconds of audio data in terms of an audio signal, and the memory controller 62 sequentially stores the audio data output from the signal processing circuit 60 into the memory circuit. 64, and read out and output at a predetermined timing.

Thus, the magneto-optical disk unit 8 can easily re-record, for example, a skipped portion by using the period until the audio data cannot be stored in the memory circuit 64.

The encoder 66 is connected to the memory controller 6
2 is converted into a recording signal in accordance with a predetermined format and output to the modulation coil 56 via the driver 68.

Thus, the magneto-optical disk section 8 forms a predetermined modulating magnetic field in accordance with the audio data, applies the modulating magnetic field to the magneto-optical disk 50, and drives the optical pickup 54 to intermittently generate the light beam. And the audio data is thermomagnetically recorded.

At this time, the encoder 66 processes the audio data in accordance with the address data output from the address decoder 70, thereby dividing successive audio data into predetermined blocks, and adding predetermined address data to each block. I do.

Further, the encoder 66 outputs the audio data of each block at a predetermined timing, thereby recording the audio data of each block in each recording area set on the magneto-optical disk 50 in advance.

Therefore, in the magneto-optical disk unit 8,
The output signal of the optical pickup 54 is output to the address decoder 70 via the amplifier circuit 72, so that the address data assigned to each recording area can be detected.

Further, in the magneto-optical disk section 8, the output signal of the amplifier circuit 72 is simultaneously output to the servo circuit 74, whereby the optical pickup 54 is driven via the servo circuit 74 so that focus control and tracking control can be performed. Has been made.

On the other hand, during reproduction, the magneto-optical disk unit 8
In the step (2), processing such as tracking control is executed by the servo circuit 74 in the same manner as during recording, and in this state, the output signal of the amplifier circuit 72 is demodulated by the decoder 76.

Thus, the magneto-optical disk unit 8 demodulates the audio data by the decoder 76, accumulates the audio data in the memory circuit 64 via the memory controller 78, and decompresses and outputs the sound by the signal processing circuit 60. I do.

At this time, by using the memory circuit 64 as a buffer memory, the magneto-optical disk unit 8 can use the period until the audio data once stored in the memory circuit 26 is output, and It is designed to be able to be easily reproduced again.

Digital-to-analog conversion circuit (D / A) 8
Numeral 0 converts a digital audio signal output from the signal processing circuit 60 into an analog signal and outputs the analog signal, whereby the audio device 1 can monitor the reproduction signal of the magneto-optical disk 50.

At the time of recording / reproduction, the servo circuit 74 monitors the output signal of the optical pickup 54 in the same manner as in the case of the compact disc player section 6, and controls the flaw detection signal S6 when sound skips due to flaws or the like. Circuit 8
Output to 2.

Further, the servo circuit 74 detects the signal levels of the focus error signal and the tracking error signal in addition to the output signal of the optical pickup 54, thereby detecting a sound skip and outputting it to the control circuit 82.

In the magneto-optical disk section 8, a control circuit 82 controls the entire operation. That is, the control circuit 8
2, the control data is output to each circuit block in response to the operation of the operation element, whereby the magneto-optical disk unit 8 is output.
The entire operation is switched, and the display unit 83
Switch the display of.

Further, the control circuit 82 detects a sound skip due to an external impact, and executes a recovery process based on the detection result. That is, the magneto-optical disk unit 8 is provided with a predetermined insulator 8 like the compact disk player unit 6.
4, the spindle motor 52 is fixed to the chassis,
Thus, the frequency of occurrence of skipping is reduced.

Further, in the magneto-optical disk section 8, an acceleration sensor (G
A sensor 86 is arranged, and outputs an output signal of the acceleration sensor 86 to a band-pass filter circuit (BPF) 88.

The band-pass filter circuit 88 extracts a signal component of an external shock from the output signal of the acceleration sensor 86, and the comparison circuit (COM) 90 compares the output signal of the band-pass filter circuit 88 with a predetermined reference level. As a result of the comparison, a vibration detection signal S7 whose signal level rises when an external shock of a certain value or more is applied to the compact disk 50 is output.

As a result, the control circuit 82 detects an accident during recording / reproduction based on the flaw detection signal S6 and the vibration detection signal S7 in the same manner as the compact disc player section 6, and sends the detection result D2 to the compact disc player section 6. Output.

Further, in this embodiment, the control circuit 8
2 executes recovery processing of the accident when the accident is detected in the magneto-optical disk section 8. On the other hand, when an accident occurs in the compact disk player section 6 during dubbing, the compact disk player section 6 The entire operation is switched based on the output control data D1, thereby performing recovery processing for this accident.

(4) Recovery Processing The control circuit 82 of the magneto-optical disk unit 8 executes the processing procedure shown in FIG. 5 when dubbing is started, and executes the recovery processing when sound skipping occurs.

That is, the control circuit 82 determines in step SP1
To step SP2, where the magneto-optical disk unit 8
It is determined whether or not a skip has occurred on the side (hereinafter, referred to as a symbol MD). If an affirmative result is obtained, the process proceeds to step SP3, executes MD skip processing, and returns to step SP2.

On the other hand, if a negative result is obtained in step SP2, the control circuit 82 proceeds to step SP4 and determines whether or not a sound skip has occurred in the compact disc player section (hereinafter referred to as a symbol CD). If an affirmative result is obtained, the process proceeds to step SP5, executes the CD skipping process, and then returns to step SP2.

On the other hand, if a negative result is obtained in step SP4, the control circuit 82 directly proceeds to step SP4.
Return to 2.

As a result, as shown in FIG.
In the case where sound skipping occurs in both the compact disk player section 6 and the magneto-optical disk section 8 and further when only the magneto-optical disk section 8 skips, the operation of both devices 6 and 8 is stopped and controlled. The recording / reproducing operation is resumed by going back by a predetermined amount.

On the other hand, if only the compact disc player section 6 skips the sound, the control circuit 82 resumes recording the audio signal by effectively using the memory circuit 26 of the compact disc player section 6, and at this time, When the capacity of the circuit 26 is insufficient and the audio signal cannot be continuously recorded, the operation of both devices 6 and 8 is stopped and controlled by a predetermined amount, as in the case where the magneto-optical disk unit 8 skips sound. The recording / reproducing operation is resumed only by going back.

Thus, in the audio device 1,
The audio signal of the compact disc player section 6 can be easily and reliably recorded even if the sound is skipped while being carried.

(5) MD skipping process In the MD skipping process as shown in FIG.
Step 2 moves from step SP6 to step SP7, in which the operation mode of the magneto-optical disk unit 8 is switched to the reproduction mode.

At this time, the control circuit 82 switches the operation mode of the optical pickup 54 immediately after the sound skip is detected, thereby reducing the light amount of the light beam applied to the magneto-optical disk 50 and reducing the amount of the recorded data. Prevents accidental erasure.

Subsequently, the control circuit 82 proceeds to step SP8, raises a recording non-permission flag which is a recording prohibition flag, and then proceeds to step SP9. Here, the control circuit 82 detects the absolute address of the magneto-optical disk 50 recorded at the time when the sound skipped, accumulates the address data in the memory circuit, and proceeds to the subsequent step SP10.

Thus, the control circuit 82 detects the recording area being recorded at the time when the sound skips.

Further, the control circuit 82 sends control data to the compact disk player section 6 and outputs
Mutes the audio signal output from. As a result, in the audio device 1, the output of the unsightly audio signal is stopped.

Subsequently, the control circuit 82 determines in step SP11
The control data is output to the compact disc player section 6, and the
Raises a reproduction non-permission flag, which is a reproduction prohibition flag.

After controlling the reproduction operation of the compact disk player section 6 to stop, the control circuit 82 detects the time data of the compact disk 10 being reproduced at the time of the sound skip in the subsequent step SP12.

The control circuit 82 detects, as the time data, absolute time information indicating the time from the beginning of the music being reproduced.
The detected time data is stored in the memory circuit. Subsequently, the control circuit 82 sends control data to the compact disc player unit 6 in step SP13, detects the remaining amount of the memory circuit 26, and then detects the playback position at which to resume in step SP14.

That is, in this embodiment, the audio signal reproduced by the compact disk 10 is output by using the memory circuit 26 as a buffer memory, so that the audio signal input to the magneto-optical disk unit 8 and the compact disk There is a time lag between the audio signal being reproduced by the player unit 6 and the audio data stored in the memory circuit 26.

That is, as shown in FIG. 8, when a skipping occurs when an audio signal of 1:30:30 is input on the magneto-optical disk unit 8 side (FIG. 8B), the compact disk player On the side of the unit 6, when there is no free space in the memory circuit 26, it means that the audio signal of 1:33:00 has already been reproduced (FIG. 8).
(A)).

For this reason, in this embodiment, an empty area of the memory circuit 26 is detected, and a time lag between the compact disk player section 6 and the magneto-optical disk section 8 is detected from the detection result.

Thus, for example, when audio data for 1 second 3 00 frames is reproduced while audio data for 3 seconds is stored in the memory circuit 26, if a sound skip occurs, 1 minute 30 seconds 00 frames are set as the starting point.

Subsequently, the control circuit 82 determines in step SP15
Then, the compact disc player unit 6 is driven to access the starting point, and the process proceeds to step SP16 to set the compact disc player unit 6 in the pause state in this state.

Further, the control circuit 82 executes the following step SP
17, the memory circuit 2 of the compact disk player section 6
After clearing No. 6, in a succeeding step SP18, the skipped portion of the magneto-optical disk unit 8 is accessed.

Here, the magneto-optical disk unit 8 roughly searches the magneto-optical disk 50 with reference to the absolute address of the magneto-optical disk 50 stored in the memory circuit, and at this time, with reference to the reproduction signal of the magneto-optical disk 50. By detecting the continuity of the address, the lack of the frame synchronization signal, and the timing at which the lock of the PLL circuit is released, the skipped portion during the recording is accessed in units of the recording area allocated to the magneto-optical disk 50.

Here, when the sound skipping portion is detected, the control circuit 82 proceeds to step SP19, where the magneto-optical disk unit 8
Is set to the pause state, and then the memory circuit 64 is cleared.

Subsequently, the control circuit 82 determines in step SP20
Then, the control data is output to the compact disc player unit 6 and the reproduction non-permission flag is turned off. Then, the process goes to step SP21, the recording non-permission flag is turned on, and the beam amount of the optical pickup 54 is turned on in the following step SP22. increase.

Subsequently, the control circuit 82 determines in step SP23
After the pause state of the compact disk player section 6 and the magneto-optical disk section 8 is released, the process proceeds to step SP2.
Then, the process proceeds to 4 and the processing procedure ends.

Thus, the compact disc player section 6 starts reproduction from the start point set in step SP14 and outputs the audio signal again, whereas the magneto-optical disc section 8 reproduces the audio signal on the compact disc player section 6. The recorded audio signals are sequentially processed to start recording, whereby the magneto-optical disk 5 is continued from the audio signal in the recording area recorded immediately before the sound skip.
0 is recorded as an audio signal.

Thus, the compact disc player section 6
When both the magneto-optical disk unit 8 and the magneto-optical disk unit 8 skip sound, and further, when only the magneto-optical disk unit 8 skips sound, by re-recording based on the address data of the compact disk 10 and the magneto-optical disk 50, The audio signal of the compact disc player section 6 can be easily and reliably recorded.

(6) CD skipping processing On the other hand, when only the compact disc player section 6 skips the sound as shown in FIG.
In the sound skipping process, from step SP25 to step S25
The process proceeds to P26, where the time data of the compact disc 10 reproduced at the time of the sound skip is detected and recorded in the memory circuit.

Subsequently, the control circuit 82 determines in step SP27
Then, the absolute address of the magneto-optical disk 50 recorded at the time of skipping is detected, the address data is stored in the memory circuit, and the flow proceeds to step SP28.

Here, the control circuit 82 determines whether or not the flaw detection signal S3 has risen. If an affirmative result is obtained, the process proceeds to step SP29.

Here, after muting the output of the audio signal, the control circuit 82 increments a predetermined counter, and determines in a subsequent step SP30 whether or not this counter has overflowed.

The control circuit 82 clears the memory circuit 26 at the same time as incrementing the counter.

If a negative result is obtained in step SP30, the control circuit 82 proceeds to step SP31, returns to the skipping point based on the time data of the compact disk 10 stored in the memory circuit, and then proceeds to step SP32. To resume the playback operation.

Subsequently, the control circuit 82 determines in step SP33
Then, it is determined again whether or not sound skipping has occurred in the compact disc player unit 6. If a negative result is obtained, the process returns to step SP26.

Thus, when the compact disc player section 6 repeatedly reproduces the same portion due to a scratch on the compact disc 10, the control circuit 82 determines in steps SP26-SP27-SP28- until the counter overflows.
SP29-SP30-SP31-SP32-SP33-
The processing procedure of SP26 is repeated.

Here, in this embodiment, the time at which the counter overflows is selected to be a time sufficiently shorter than the audio data stored in the memory circuit 26.

As a result, in the audio device 1,
When the reproduction of the audio signal is repeated for the damaged portion and the reproduction can be performed without skipping in a range where the counter does not overflow, by continuing to step SP43, a continuous audio signal can be recorded.

On the other hand, if the compact disc player section 6 repeatedly reproduces the same portion due to a scratch on the compact disc 10, a positive result is obtained in step SP30, so that the control circuit 82 falls into a so-called overhang state. And proceeds to step SP34.
After muting the output of the audio signal, step SP
Move on to 35.

Here, the control circuit 82 outputs control data to the compact disc player section 6 to allow the compact disc player section 6 to access the beginning of the next tune skipped, and then proceeds to step SP36 to proceed to step SP36. The part 6 is set to the pause state.

Subsequently, the control circuit 82 determines in step SP37
After raising the recording non-permission flag for the magneto-optical disk unit 8 in step (1), the operation mode is switched to the reproduction mode.

Subsequently, the control circuit 82 determines in step SP38
Then, the head address of the track is accessed for the skipped music based on the address data stored in the memory circuit, and in step SP39, predetermined character data is recorded from the recording position of the head address.

This character data is, as shown in FIG.
When you play this track,
This is data for displaying on the display 83 a message indicating that the recording could not be performed due to a scratch on the compact disc 10 together with the track number (in this case, 05).

When this character data is recorded, the control circuit 8
2 sets the character data recording completion position to the end address of this track in the following step SP40, and clears the counter in the following step SP41.

Subsequently, the control circuit 82 determines in step SP42
Then, the compact disc player section 6 and the magneto-optical disc section 8 are switched to the reproduction and recording modes, respectively, thereby starting the recording of the music that skips over the skipped music, and proceeds to step SP44 to execute the processing procedure. Complete.

Thus, even when the same portion is repeatedly reproduced due to a scratch on the compact disc 10, recording can be performed without re-dubbing.
The audio signal of 0 can be easily and reliably recorded, and the usability of the audio apparatus 1 can be improved.

Furthermore, by recording the character data at this time, it is possible to display in the audio device 1 that dubbing could not be performed based on the character data, thereby improving the usability of the audio device 1. .

On the other hand, if the compact disc player section 6 skips sound due to an external impact, step SP2
8, a negative result is obtained, so that the control circuit 8
2 proceeds directly to step SP31 and sequentially proceeds to step SP31.
The processing procedure of 32-SP33 is executed.

Here, if the compact disc player section 6 skips sound due to an impact, the control circuit 82 determines in step S that the skipping is not repeatedly detected.
A negative result is obtained in P33, and the following step SP4
Move to 3.

Here, the control circuit 82 determines whether or not all the audio data stored in the memory circuit 26 has been output and the memory circuit 26 is empty. If a negative result is obtained here, the control circuit 82 proceeds to step SP45. , Clear the counter.

At the same time, the control circuit 82 outputs the control data to the compact disc player section 6 and repeats the reproduction of the skipped portion, whereby the audio data stored in the memory circuit 26 in the audio device 1 is output. By using the period until the sound is skipped, the skipped portion is reproduced again.

Thus, the control circuit 82 determines at step SP4
When the processing of No. 5 is executed, the process subsequently moves to step SP44, and this processing procedure is completed.

On the other hand, if skipping occurs frequently, the memory circuit 26 eventually becomes empty, and a positive result is obtained in step SP43.

In this case, as shown in FIG.
Moves to step SP46, in which the recording operation of the magneto-optical disk unit 8 is stopped and set to a pause state. Then, in step SP47, the recording non-permission flag is raised and the mode is switched to the reproduction mode.

Further, the control circuit 82 executes the following step SP
After stopping the reproduction operation of the compact disk player section 6 at 48, the pause state is set at the subsequent step SP49.

The control circuit 82 subsequently proceeds to step S
After moving to P50, control data is sent to the compact disc player section 6 to return to the beginning of the song being reproduced, and then to step SP51, where a pause state is set.

The control circuit 82 subsequently proceeds to step S
After moving to P52, the optical pickup 54 is moved to the head recording position of the song being recorded, and then to step SP53, where it is set to a pause state.

Subsequently, the control circuit 82 proceeds to step SP54.
After the mode is switched to the recording mode in the magneto-optical disk unit 8, the process proceeds to step SP55, and the pause state of the compact disk player unit 6 and the magneto-optical disk unit 8 is released.

As a result, in the audio device 1,
If only the compact disc player section 6 skips sound, dubbing is resumed in units of the tune being recorded, and the process proceeds to step SP44 to complete the processing procedure.

Thus, the compact disc player section 6
Even when the sound skips, the operation of re-dubbing can be omitted, whereby the audio signal of the compact disc player section 6 can be simply and reliably recorded.

(7) Effects of the Embodiment According to the above configuration, in the disc recording / reproducing apparatus 1, during dubbing, the compact disc player 6 repeats the same part for a predetermined time or more due to a scratch on the compact disc 10. When reproducing, the magneto-optical disk unit 8
Is necessary to interrupt the recording operation on the magneto-optical disk 50 and to move the compact disk player unit 6 away from the same location, thereby muting the output of the audio signal S4 repeatedly reproduced at the same location and necessitating Accordingly, the next predetermined portion based on the same portion can be reproduced, and thus the user's labor can be saved by that much as compared with the case where the user ends the dubbing and redoes the dubbing again.

Furthermore, in the disk recording / reproducing apparatus 1, the magneto-optical disk unit 8 records character information indicating that recording was interrupted in the management area of the magneto-optical disk 50 during dubbing, so that Based on this, it is possible to notify the user that the song corresponding to the scratched portion on the compact disc 10 could not be dubbed, thus improving the usability of the user.

(8) Other Embodiments In the above-described embodiment, dubbing is performed in units of recording when skipping occurs in the magneto-optical disk unit, and in units of music when skipping occurs only in the compact disk player unit. Although the case where the dubbing is performed has been described, the present invention is not limited thereto, and dubbing may be performed again in units of music and recording.

Further, in the above-described embodiment, the case where sound skipping is detected with reference to the output signal of the optical pickup has been described. However, the present invention is not limited to this, and the present invention is not limited thereto. Sound skipping may be detected by detecting the soundness.

Further, in the above-described embodiment, a case has been described in which sound skipping is detected based on the reproduction signal, tracking error signal, and focus error signal output from the optical pickup. However, the present invention is not limited to this. ,
Sound skipping may be detected based on any of these signals.

Further, in the above-described embodiment, the case of dubbing an audio signal composed of an analog signal has been described. However, the present invention is not limited to this, and the audio signal may be dubbed in the form of a digital signal. May dub image data.

[0129]

As described above, according to the present invention, in a disc recording / reproducing apparatus for dubbing an information signal reproduced from a first disc-shaped recording medium to a second disc-shaped recording medium, the first signal is used when dubbing. When the reproducing means repeatedly reproduces the same portion for a predetermined time or more due to the scratch on the disc-shaped recording medium, the recording operation on the second disc-shaped recording medium is interrupted and the reproducing means is separated from the same portion. The output of the information signal that is repeatedly reproduced at the same location can be muted, and the next predetermined location based on the same location can be reproduced as needed, thus enabling the user A disk recording / reproducing apparatus which can improve usability can be realized.

Further, according to the present invention, the second disk-shaped recording medium has a management area for managing character information corresponding to the recorded information signal, and the second disk-shaped recording medium recorded on the second disk-shaped recording medium. In response to the information signal corresponding to the same location repeatedly reproduced from the disc-shaped recording medium, the character information indicating that the recording has been interrupted is recorded in the management area. The user can be notified that the song corresponding to the scratched portion on the disc-shaped recording medium could not be dubbed, and a disc recording / reproducing apparatus which can improve the usability of the user can be realized.
