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

(1) External Configuration In FIG. 1, reference numeral 1 denotes a portable audio device as a whole, in which speakers 2 and 4 are arranged on the left and right, and a compact disk player section 6 and the like are arranged in the center thereof.

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. In addition, the reproduction signals of the compact disc player unit 6 and the magneto-optical disc unit 8 can be monitored via the speakers 2 and 4.

On the other hand, on the front surface of the audio apparatus 1, there are arranged operators for the compact disk player section 6 and the magneto-optical disk section 8 and a display section for displaying the operation mode and the like, whereby the title of the music being reproduced, etc. Is made to be able to confirm.

(2) Compact Disk Player Unit As shown in FIG. 2, the compact disk player unit 6
Drives the compact disc 10 to rotate by the spindle motor 12, and in this state, processes the reproduction signal S1 output from the optical pickup 14 to reproduce the compact disc 10.

That is, the compact disk player unit 6
At the RF signal processing circuit 16, the optical pickup 1
The reproduced signal S1 of No. 4 is amplified, converted into a binarized 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. As a result, in the servo circuit 20, the optical pickup 1 is transmitted via the driver circuit 22.
4 is driven to perform tracking control and focus control.

Further, the RF signal processing circuit 16 detects a scratch on the compact disk 10 by detecting the signal level of the reproduction signal S1, and the detection result is the scratch detection signal S.
Output as 3.

Here, as shown in FIG. 3, when the compact disk 10 is scratched, the optical pickup 14 is also used.
However, in this type of compact disc player, the audio data cannot be corrected 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 that is intermittently output.

In the reproduction 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 along with this, the focus error signal. FE (FIG. 3 (B)) and tracking error signal TE (FIG. 3 (C)) also change greatly. As a result, the RF signal processing circuit 16 detects a change in the amplitude of the reproduction signal S1, the focus error signal FE, and the tracking error signal TE to generate a scratch detection signal S3 whose signal level rises at the scratch portion. .

Incidentally, when the optical pickup 14 is track-jumped by an external impact, the reproduction signal S1, the focus error signal FE, and the tracking error signal TE are changed as in the case of a scratch. However, since the change of the reproduction signal S1 is different between the case of a scratch and the case of an external shock, in the case of this embodiment, the pass band has a frequency of 30 to 300.
Playback signal S1 through the band pass filter circuit of [Hz]
By detecting the amplitude fluctuation of the signal, the change of the focus error signal FE, and the change of the tracking error signal TE, it is possible to reliably detect only the case of a flaw.

The signal processing circuit 18 is the RF signal processing circuit 1.
The binarized signal output from 6 is subjected to signal processing, whereby the audio data is demodulated, and error correction processing and deinterleave processing are executed and output.

The memory controller 24 includes the memory circuit 2
By controlling the input / output of 6, the memory circuit 26 is used as a buffer memory for audio data. That is, in the memory circuit 26, about 3 seconds of audio data converted into an audio signal can be accumulated, and the memory controller 24 sequentially stores the audio data output from the signal processing circuit 18 in the memory circuit 26. At the same time, it is read and output at a predetermined timing.

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

The digital-to-analog digital conversion circuit (D / A) 28 converts the audio data output from the memory controller 24 into an analog signal, and then outputs the analog signal via the output circuit 30. As a result, in the audio apparatus 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 necessary. .

In the compact disk player unit 6, the control circuit 32 controls the entire operation. That is, in the control circuit 32, control data is output to each circuit block in response to the operation of the operation element, whereby the operation of the entire compact disk player unit 6 is switched, and further, the display of the display unit 34 is switched as necessary. .

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

Further, in the compact disk player unit 6, an acceleration sensor (G sensor) 38 is arranged on the same base as the spindle motor 12, and an output signal of the acceleration sensor 38 is used as a band pass filter circuit (BPF) 4.
Output to 0. The bandpass filter circuit 40 extracts a signal component of an external impact from the output signal of the acceleration sensor 38, and then a comparison circuit (COM) 42 obtains a comparison result with a predetermined reference level. When an external impact of (3) is applied to the compact disk 10, a vibration detection signal S5 whose signal level rises is output.

As a result, the control circuit 32 causes the flaw detection signal S
3 and the vibration detection signal S5 are used as references to detect an accident during reproduction, and the detection result D1 is output to the magneto-optical disk unit 8.

Further, in this embodiment, the control circuit 32
When the compact disk player unit 6 detects an accident, the recovery process of the accident is executed, while when the magneto-optical disk unit 8 also causes an accident during recording,
The entire operation is switched on the basis of the control data D2 output from the magneto-optical disk unit 8, whereby the audio signal can be surely recorded / reproduced in the entire apparatus.

(3) Magneto-optical disk unit As shown in FIG. 4, the magneto-optical disk unit 8 outputs the 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 operator.

That is, in the magneto-optical disk unit 8,
The magneto-optical disk 50 is rotationally driven 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 disc unit 8, the reproduction signal S4 output from the compact disc player unit 6 is converted into a digital signal by the analog digital conversion circuit (A / D) 58 and then input to the signal processing circuit 60.

Here, the signal processing circuit 60 audio-compresses the digital audio signal and outputs it. The memory controller 62 controls the input / output of the memory circuit 64 to use the memory circuit 64 as a buffer memory for audio data.

That is, in the memory circuit 64, about 3 seconds of audio data converted into an audio signal can be stored, and the memory controller 62 sequentially outputs the audio data output from the signal processing circuit 60 to the memory circuit. The data is stored in 64 and is read out and output at a predetermined timing. As a result, the magneto-optical disk unit 8
For example, by utilizing the period until the audio data cannot be stored in the memory circuit 64, for example, a skipped portion can be easily re-recorded.

The encoder 66 is the memory controller 6
The audio data output from 2 is converted into a recording signal according to a predetermined format and is output to the modulation coil 56 via the driver 68. As a result, the magneto-optical disk unit 8 forms a predetermined modulating magnetic field according to the audio data, applies the modulating magnetic field to the magneto-optical disk 50, and drives the optical pick-up 54 to intermittently irradiate the light beam. , Thermomagnetically record audio data.

At this time, in the encoder 66, the audio data is processed according to the address data output from the address decoder 70, whereby the audio data that is successively continuous is divided into predetermined blocks, and the predetermined address data is assigned to each block. Is added. 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 preset on the magneto-optical disk 50. 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, whereby the address data assigned to each recording area can be detected. .

Further, in the magneto-optical disk unit 8, at the same time, the output signal of the amplifier circuit 72 is output to the servo circuit 74 so that the optical pick-up 54 can be driven via the servo circuit 74 to perform focus control and tracking control. Has been done. On the other hand, during reproduction, in the magneto-optical disk unit 8, the servo circuit 7 is used in the same manner as during recording.
In step 4, processing such as tracking control is executed, and in this state, the decoder 76 demodulates the output signal of the amplifier circuit 72.

As a result, the magneto-optical disk unit 8 demodulates the audio data by the decoder 76, stores the audio data in the memory circuit 64 via the memory controller 78, and outputs the audio data expanded by the subsequent signal processing circuit 60. To do. At this time, the magneto-optical disk unit 8 has the memory circuit 6
By using 4 as a buffer memory, for example, a skipped portion can be easily reproduced again by utilizing the period until the audio data once stored in the memory circuit 26 is output.

Digital analog conversion circuit (D / A) 8
0 converts the digital audio signal output from the signal processing circuit 60 into an analog signal and outputs the analog signal, so that the audio device 1 can monitor the reproduction signal of the magneto-optical disk 50. At the time of this recording / reproducing, in the servo circuit 74, the output signal of the optical pickup 54 is monitored as in the case of the compact disk player unit 6, and when the sound skips due to a scratch or the like, the scratch detection signal S6 is sent to the control circuit 82. Output.

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 pick-up 54, detects the skipped sound, and outputs the detected signal to the control circuit 82. .

In the magneto-optical disk unit 8, the control circuit 82 controls the entire operation. That is, the control circuit 8
In 2, the control data is output to each circuit block in response to the operation of the operator, whereby the magneto-optical disk unit 8
The entire operation is switched, and if necessary, 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 disc unit 8 has a predetermined insulator 8 like the compact disc player unit 6.
The spindle motor 52 is fixed to the chassis via 4,
This reduces the frequency of sound skipping.

Further, in the magneto-optical disk unit 8, the acceleration sensor (G
Sensor) 86, and outputs an output signal of the acceleration sensor 86 to a bandpass filter circuit (BPF) 88. The band pass filter circuit 88 extracts a signal component of an external impact from the output signal of the acceleration sensor 86, and the comparison circuit (COM) 90 outputs the band pass filter circuit 8
By obtaining the result of comparison between the output signal of 8 and a predetermined reference level, the vibration detection signal S whose signal level rises when an external shock of a certain value or more is applied to the compact disk 50.
7 is output.

As a result, the control circuit 82 detects an accident during recording / reproduction on the basis of the scratch detection signal S6 and the vibration detection signal S7 as in the compact disc player section 6, and outputs the detection result D2 to the compact disc player section 6. Output.

Further, in this embodiment, the control circuit 82
When an accident is detected by the magneto-optical disk unit 8, the recovery process of this accident is executed, while when an accident occurs in the compact disk player unit 6 during dubbing, the compact disk player unit 6 outputs the same. Based on the control data D1, the entire operation is switched, and the recovery process for this accident is executed.

(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 uses the step SP1.
To step SP2, where the magneto-optical disk unit 8
It is determined whether or not sound skipping has occurred on the side (hereinafter referred to as the symbol MD). If a positive result is obtained here, the process proceeds to step SP3 to execute MD sound skipping 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 skip has occurred on the compact disk player unit (hereinafter referred to as symbol CD) side. If a positive result is obtained here, the process proceeds to step SP5 to execute the CD skip processing, and then returns to step SP2.

On the other hand, when a negative result is obtained at step SP4, the control circuit 82 directly determines at step SP4.
Return to 2. As a result, as shown in FIG. 6, in the control circuit 82, when sound skipping occurs in both the compact disk player unit 6 and the magneto-optical disk unit 8, and when only the magneto-optical disk unit 8 skips sound, both Equipment 6
After the operations of and 8 are stopped and controlled, the recording / reproducing operation is restarted by going back a predetermined amount.

On the other hand, when only the compact disk player section 6 skips, the control circuit 82 effectively utilizes the memory circuit 26 of the compact disk player section 6 to restart the recording of the audio signal, and at this time, the memory. When the capacity of the circuit 26 is insufficient and it becomes impossible to continuously record the audio signal, the operation of both the devices 6 and 8 is stopped and controlled by a predetermined amount as in the case where the magneto-optical disk unit 8 skips. The recording / reproducing operation is restarted just back.

As a result, in the audio device 1,
The audio signal of the compact disc player unit 6 can be easily and surely recorded even if the user skips the sound by carrying it.

(5) MD sound skip processing As shown in FIG. 7, in the MD sound skip processing, the control circuit 8
Step 2 shifts from step SP6 to step SP7, where the operation mode of the magneto-optical disk unit 8 is switched to the reproduction mode. At this time, the control circuit 82 immediately switches the operation mode of the optical pickup 54 when the sound skip is detected, thereby reducing the light amount of the light beam applied to the magneto-optical disk 50 and erasing the recorded data by mistake. Prevent it in advance.

Subsequently, the control circuit 82 proceeds to step SP8 to raise a recording disapproval 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 skips, stores this address data in the memory circuit, and moves to the next step SP10.
As a result, the control circuit 82 detects the recording area being recorded when the sound skips.

Further, the control circuit 82 sends the control data to the compact disc player unit 6, and the speakers 2, 4
Mute the audio signal output from. As a result, the audio device 1 stops outputting the audio signal, which is difficult to hear.

Then, the control circuit 82 proceeds to step SP11.
Then, the control data is output to the compact disc player unit 6, and the compact disc player unit 6 is controlled by the control data.
On the side, the reproduction prohibition flag which is a reproduction prohibition flag is activated. As a result, the control circuit 82 controls the stop operation of the reproducing operation of the compact disk player unit 6, and then detects the time data of the compact disk 10 which was reproduced at the time of skipping the sound in the subsequent step SP12.

The control circuit 82 detects absolute time information indicating the time from the beginning of the music being reproduced as this time data,
The detected time data is accumulated in the memory circuit. Subsequently, the control circuit 82 moves to step SP13 and sends the control data to the compact disk player unit 6, detects the remaining amount of the memory circuit 26, and then detects the reproduction position to be resumed at the subsequent step SP14.

In other words, in this embodiment, by using the memory circuit 26 as a buffer memory and outputting the audio data reproduced from the compact disk 10, the audio signal inputted to the magneto-optical disk section 8 and the compact disk player section are outputted. There is a time lag between the audio signal being reproduced in 6 and the audio data accumulated in the memory circuit 26.

That is, as shown in FIG. 8, when a skip occurs when the audio signal of 1 minute 30 seconds 00 frame is input on the side of the magneto-optical disk unit 8 (FIG. 8 (B)), the compact disk player On the part 6 side, when there is no free space in the memory circuit 26, it means that the audio signal of 1 minute 33 seconds 00 frame has already been reproduced (FIG. 8).
(A)). Therefore, in this embodiment, the empty area of the memory circuit 26 is detected, and the time lag between the compact disk player section 6 and the magneto-optical disk section 8 is detected from the detection result.

As a result, the control circuit 82, for example, in the case where audio data for 3 seconds is accumulated in the memory circuit 26 and a skip occurs when reproducing an audio signal of 1 minute 33 seconds 00 frame, Set the start point to 1 minute 30 seconds 00 frames.

Subsequently, the control circuit 82 proceeds to step SP15.
Then, the compact disk player unit 6 is driven to access the starting point, and the process proceeds to step SP16 where the compact disk player unit 6 is set to the paused state. Further, the control circuit 82 clears the memory circuit 26 of the compact disk player unit 6 in the following step SP17, and then accesses the skipped portion of the magneto-optical disk unit 8 in the following step SP18.

Here, the magneto-optical disk unit 8 roughly searches the magneto-optical disk 50 based on the absolute address of the magneto-optical disk 50 stored in the memory circuit, and at this time, based on 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 lost, the location where the sound skips during recording is accessed in the unit of the recording area assigned to the magneto-optical disk 50.

When the sound skipping point is detected, the control circuit 82 moves to step SP19, and the magneto-optical disk unit 8
Is set to a pause state, and then the memory circuit 64 is cleared. Then, the control circuit 82 proceeds to step SP20, outputs control data to the compact disk player unit 6 to turn off the reproduction non-permission flag, and then proceeds to step SP.
In step 21, the recording non-permission flag is raised and the beam quantity of the optical pickup 54 is raised in step SP22.

Subsequently, the control circuit 82 proceeds to step SP23.
Then, after releasing the paused state of the compact disk player unit 6 and the magneto-optical disk unit 8, step SP2
Then, the processing procedure is finished. As a result, the compact disc player unit 6 starts reproduction from the start point set in step SP14 and outputs the audio signal again, whereas the magneto-optical disc unit 8 reproduces the audio signal reproduced by the compact disc player unit 6. The signals are sequentially processed and recording is started, whereby the audio signal is recorded on the magneto-optical disk 50 so as to be continuous from the audio signal in the recording area recorded immediately before the skip.

Thus, the compact disk player unit 6
When both the magneto-optical disk unit 8 and the magneto-optical disk unit 8 skip sound, and when only the magneto-optical disk unit 8 skips sound, the address data of the compact disk 10 and the magneto-optical disk 50 is used as a reference for re-recording. The audio signal of the compact disc player unit 6 can be recorded easily and surely.

(6) CD skipping process On the other hand, when only the compact disk player unit 6 skips as shown in FIG. 9, the control circuit 82 causes the CD
In the skip processing, steps SP25 to S
Moving to P26, the time data of the compact disk 10 being reproduced at the time of skipping the sound is detected and recorded in the memory circuit.

Then, the control circuit 82 proceeds to step SP27.
Then, the absolute address of the magneto-optical disk 50 recorded at the time when the sound is skipped is detected, the address data is stored in the memory circuit, and the process proceeds to step SP28. Here, the control circuit 82 determines whether or not the scratch detection signal S3 is rising, and if a positive result is obtained, the control circuit 82 proceeds to step SP29.

Here, the control circuit 82 mutes the output of the audio signal, increments a predetermined counter, and determines at the subsequent step SP30 whether or not this counter has overflowed. The control circuit 82 clears the memory circuit 26 at the same time when the counter is incremented.

When a negative result is obtained at step SP30, the control circuit 82 proceeds to step SP31, returns to the sound skipping location based on the time data of the compact disk 10 stored in the memory circuit, and then proceeds to step SP32. Then, the playback operation is restarted. Subsequently, the control circuit 82 proceeds to step SP33, determines again whether or not skipping has occurred in the compact disk player unit 6, and if a negative result is obtained, returns to step SP26.

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

In this embodiment, the overflow time of this counter is selected to be sufficiently shorter than the audio data stored in the memory circuit 26. As a result, in the audio device 1, the audio signal is repeatedly reproduced for the scratched portion, and if reproduction can be performed without skipping within the range where the counter does not overflow, the process moves to step SP43 to record continuous audio signals. be able to.

On the other hand, when the compact disc player unit 6 repeatedly reproduces the same portion due to the scratch on the compact disc 10, a positive result is obtained in step SP30, and the control circuit 82 falls into a so-called overhang state. Judging that it was vine, move to step SP34,
After muting the audio signal output, step SP
Move to 35.

Here, the control circuit 82 outputs the control data to the compact disc player unit 6 to access the compact disc player unit 6 at the beginning of the next tune skipped, and then moves to step SP36 for compact disc player. Set part 6 to the paused state. Subsequently, the control circuit 82 proceeds to step SP37 to raise the recording non-permission flag for the magneto-optical disk unit 8 and then switches the operation mode to the reproduction mode.

The control circuit 82 then proceeds to step SP38.
Then, the head address of the track for the skipped music is accessed with reference to the address data stored in the memory circuit, and a predetermined character data is recorded from the recording position of this head address in the following step SP39.

This character data is, as shown in FIG.
When playing this track, for the song in this part,
This data is used to display a message indicating that recording could not be performed due to scratches on the compact disk 10 on the display unit 83 together with the track number (in this case, 05). When this character data is recorded, the control circuit 82 proceeds to the next step S.
In P40, the recording completion position of the character data is set to the end address of this track, and in the subsequent step SP41, the counter is cleared.

Then, the control circuit 82 proceeds to step SP42.
Then, the compact disc player unit 6 and the magneto-optical disc unit 8 are switched to the reproducing and recording modes, respectively, whereby the skipped music is skipped and the recording of the following music is started, and the processing is moved to Step SP44. Complete.

Thus, even if the same portion is repeatedly reproduced due to scratches on the compact disk 10, recording can be performed without re-dubbing, whereby the compact disk 1 can be recorded.
The audio signal of 0 can be recorded easily and surely to improve the usability of the audio apparatus 1.

Further, by recording the character data at this time, it can be displayed on the audio apparatus 1 that the dubbing could not be performed based on the character data, whereby the usability of the audio apparatus 1 can be improved. .

On the other hand, when the compact disk player unit 6 skips due to an external impact, step SP2
When the negative result is obtained in 8, the control circuit 8
Step 2 directly moves to step SP31 and sequentially proceeds to step SP31.
The processing procedure of 32-SP33 is executed. If the compact disk player unit 6 skips due to an impact,
Since the sound skip is not repeatedly detected, the control circuit 8
In step 2, a negative result is obtained in step SP33, and the process proceeds to the following step SP43.

Here, the control circuit 82 judges whether or not all the audio data accumulated in the memory circuit 26 has been output and the memory circuit 26 has become 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 unit 6 and repeats the reproduction of the skipped portion, whereby the audio device 1
By utilizing the period until the audio data once stored in the memory circuit 26 is output, the skipped portion is reproduced.

Thus, the control circuit 82 is connected to the step SP4.
When the process of 5 is executed, the process proceeds to step SP44 to complete this process procedure.

On the other hand, if skipping occurs frequently, the memory circuit 26 becomes empty at last, and a positive result is obtained in step SP43. In this case, as shown in FIG. 11, the control circuit 82 proceeds to step SP46, where the recording operation of the magneto-optical disk unit 8 is stopped and set to the pause state, and then the recording disapproval flag is set at the subsequent step SP47. Turn up and switch to playback mode.

Further, the control circuit 82 follows the subsequent step SP.
At 48, the reproduction operation of the compact disk player unit 6 is stopped and controlled, and then at step SP49, a pause state is set. Further, the control circuit 82 continues to step SP.
In step 50, the control data is sent to the compact disc player unit 6 to return to the beginning of the music being reproduced, and then in step SP51, a pause state is set.

Further, the control circuit 82 continues to step S
After moving to P52, the optical pickup 54 is moved to the head recording position of the music being recorded, and then to SP53, where a pause state is set. Subsequently, the control circuit 82 moves to step SP54, switches the magneto-optical disk unit 8 to the recording mode here, and then moves to step SP55 to release the paused state of the compact disk player unit 6 and the magneto-optical disk unit 8.

As a result, in the audio device 1,
When only the compact disc player unit 6 skips, dubbing is restarted for each piece of music being recorded, and then the process proceeds to step SP44 to complete the processing procedure. Thus, even if the compact disc player unit 6 skips a sound, the operation of re-dubbing can be omitted, whereby the audio signal of the compact disc player unit 6 can be easily and surely recorded.
