2. Description of the Related Art A recording device such as an MD (mini-disc) recorder capable of recording music data (audio signal) reproduced by a reproducing device such as a player is known. Such a recording device can record on a recording medium such as an MD without substantially deteriorating the sound quality of the reproduced music data. It is also widely used because editing such as replacement of recorded music is easy. Recently, a recording device capable of recording music data (high-speed recording) reproduced at high speed (high-speed reproduction) by a reproducing device is also known. Such a recording device can reduce the time required for recording, and can record more songs in the same time.

[0003]

Generally, when a recording surface of a CD or the like reproduced by a reproducing apparatus has a flaw or the like, sound skipping occurs at the time of reproducing the portion. This skipping does not occur during normal playback (normal playback: playback at a normal speed) with a playback device depending on the size of the scratches on the recording surface, etc., but during high-speed playback. May occur. In a conventional recording device capable of high-speed recording, skipping occurs on the playback device side during high-speed recording, and even if a recording error actually occurs, it is difficult for the user to judge, and recording has been continued as it is. That is, even if the audio signal of the music is output from the recording device or the like during the high-speed recording, it is not easy to recognize the occurrence of the skipping or the like from the audio output that is performed early. Further, the recording device may mute the audio output of the music being recorded only during high-speed recording.
For this reason, the user recognizes, for the first time, a recording error due to a skip or the like when reproducing the music data recorded by the recording device at the normal speed. And the user
It was necessary to redo the recording of the music that caused the recording error due to skipping.

[0004] Also, even if the user can recognize a skip or the like during high-speed recording, re-recording may not be possible immediately. For example, in high-speed recording, skipping is recognized before the end of the recording of the first song, and even if the user attempts to perform high-speed recording again, the recording is performed for a certain period of time by the copyright protection mechanism generally provided in the recording device. Will be banned. More specifically, a recording device generally has a predetermined copyright protection mechanism. Then, by the copyright protection mechanism, the recording device starts a high-speed recording Wait timer at the time of recording. Once the recording is started, even if the user stops the recording in the middle or the recording is automatically terminated, the recording device resumes the high-speed recording while the Wait timer is running. Is banned. For this reason, even if the user can recognize a recording error due to skipping during high-speed recording, there is a problem that high-speed recording cannot be performed again immediately.

I do.

DAC (Digital / Analog Converter)
111 converts the digital music data supplied from the signal processing circuit 102 into an analog music signal, and outputs the converted music signal as audio (music) via a predetermined amplifier, speaker, and the like.

Next, the disk reproducing apparatus 2 will be described. The disc reproducing apparatus 2 is, for example, a reproducing apparatus that uses a CD (compact disc) as a recording medium to be reproduced, and includes a processing control unit 201, a signal processing circuit 202, a spindle servo circuit 203, an optical pickup 204,
Tracking thread servo circuit 205 and display unit 20
6, a key input unit 207, and a DAC 208.

The processing control unit 201 includes a CPU and peripheral LS
It is composed of a one-chip microcomputer or the like including I, and controls the entire disc reproducing apparatus 2. That is, the processing control unit 201
Controls the signal processing circuit 202 and the like to read out music data (audio signals) recorded on a recording medium CD,
The read music data is supplied to the disk recording device 1 via the digital data line 4. At that time, the processing control unit 201 transmits the disc recording device 1 via the communication line 3.
Is controlled in either normal playback or high-speed playback.
The music data recorded in D is reproduced. For example, when high-speed reproduction is instructed from the disk recording device 1, the processing control unit 201 sequentially supplies the music data reproduced by high-speed reproduction to the disk recording device 1 via the digital data line 4.

Further, the processing control unit 201 sends, through the signal processing circuit 202, the Q in the frame of the CD to be reproduced.
By monitoring the continuity of the code, the occurrence of skipping is detected. More specifically, the processing control unit 201 reads the internal Q code via the signal processing circuit 202 based on a sync signal (for example, 13.3 ms during normal reproduction and 1x speed during high-speed reproduction), and tracks therein. The continuity of the number / reproduction total time (minute, second, frame) is constantly monitored. That is, the continuity is monitored by comparing the data read last time with the data read this time.

That is, when normal reproduction is being performed, the total reproduction time is continuous (frames are continuous). However, when skipping occurs due to a scratch or the like in the CD, the total reproduction time is not continuous. That is, one of the minute, second, and frame is not continuous. As described above, the processing control unit 201 detects the occurrence of skipping by monitoring the continuity of the Q code via the signal processing circuit 202. When detecting the occurrence of the skip, the processing control unit 201 supplies information indicating that the skip occurs to the disc recording device 1 via the communication line 3.

The signal processing circuit 202 controls a spindle servo circuit 203, an optical pickup 204, a tracking thread servo circuit 205, and the like. Then, the music data stored in the CD to be reproduced is read out via the optical pickup 204. The signal processing circuit 202 decodes the read music data, and supplies the decoded music data to the disk recording device 1 via the digital data line 4.

The spindle servo circuit 203 controls the drive of a spindle motor (not shown) for rotating a predetermined turntable on which a CD is mounted, and rotates the spindle motor at a predetermined rotation speed. Note that the spindle servo circuit 203
Under the control of the signal processing circuit 202, the spindle motor and the like are driven at a rotation speed corresponding to either high-speed reproduction or normal reproduction.

The optical pickup 204 irradiates a laser beam of a predetermined wavelength toward a pit or the like provided on the recording surface of the CD, and receives the reflected light to convert it into an electric signal. The optical pickup 204 supplies the converted electric signal to the signal processing circuit 202 as music data or the like.

Tracking sled servo circuit 205
Drives a thread motor (not shown) for moving the optical pickup 204 in the radial direction of the CD serving as a recording medium, and moves the optical pickup 204 to a predetermined position on the recording surface of the CD.

The display unit 206 is composed of an LCD panel or the like, and is controlled by the processing control unit 201 to display a predetermined character string or the like in order to clarify the operation status or the like to the user.

The key input unit 207 includes predetermined button switches, rotary switches, and the like. The key input unit 207 inputs instruction information and the like in accordance with a user's operation, and processes the input information.
Feed to 1.

The DAC 208 converts the digital music data transmitted from the signal processing circuit 202 into an analog music signal, and outputs the converted music signal as voice (music) via a predetermined amplifier, speaker, and the like.

Hereinafter, a recording process performed by the disk recording device 1 according to the embodiment of the present invention will be described with reference to FIG. FIG. 3 is a flowchart for explaining a recording process in which the disk recording device 1 records music data in consideration of a skipping or the like generated in the disk reproducing device 2. The recording process shown in FIG. 3 is performed by a key input unit 107 when a user is loaded with a recordable MD in the disc recording device 1 and a CD to be reproduced is loaded in the disc reproducing device 2. Triggered when entered.

First, the processing control section 101 determines whether or not the recording instruction is a new recording (step S11). That is, the processing control unit 101 determines whether the recording instruction input by the user from the key input unit 107 is a new recording.

If the processing control section 101 determines that the recording is a new recording, the processing control section 101 stores the track number for specifying the music to be reproduced by the disk reproducing device 2 in the reproduction music area 91 of the memory 109 (step S12). That is, the processing control unit 101 stores the track numbers of the music pieces that are to be played back by the disk playback device 2 and are to be recorded by the disk recording device 1.

On the other hand, if it is determined that the recording is not a new recording (re-recording), the processing control unit 101
3 is transferred to the reproduction music area 91 (step S13). That is, when re-recording a tune having a recording error due to skipping or the like generated in the disc reproducing device 2 by the previously performed recording process, the re-recording target stored in the re-recorded tune area 93 Is transferred to the reproduction music area 91.

The processing control unit 101 initializes the recording state area 92 and the re-recorded music area 93 (step S1).
4). That is, the processing control unit 101 sets the playback music area 9
1 by the number corresponding to all the track numbers stored in
“Unrecorded” is set in the track in the recording state area 92. Further, the processing control section 101 clears the re-recorded music area 93.

The processing control unit 101 controls the disc playback device 2
, And starts recording music data (step S15). That is, the processing control unit 101 instructs the disc reproducing device 2 to reproduce each music according to the track number stored in the reproduction music area 91, and acquires the music data transmitted via the digital data line 4. Then, the magnetic head driver 110 and the like are controlled to sequentially record music data on the MD. Note that the processing control unit 101 instructs the disk reproducing device 2 to perform high-speed reproduction and high-speed recording when the recording is new, and instructs normal reproduction and normal recording when re-recording. Do.

When recording is started, the processing control unit 101
“Recording NG” is set to the track in the recording state area 92 corresponding to the music currently being recorded (step S16). That is, the processing control unit 101 temporarily sets “recording NG” in consideration of occurrence of skipping in the music currently being recorded. In this track, when recording is normally performed without any skipping, “recording OK” is set in step S20 described later.

The processing control unit 101 controls the disc playback device 2
It is determined whether or not sound skipping has occurred (step S1).
7). That is, the processing control unit 101 determines whether or not information indicating that a sound skip has occurred has been transmitted from the disk reproducing device 2.

When it is determined that no sound skip has occurred, the process control section 101 determines whether or not a stop instruction has been input (step S18). That is, the process control unit 101 determines whether an instruction to stop recording has been input by the user via the key input unit 107.

When the processing control section 101 determines that the stop instruction has been input, the processing advances to step S25 described later. On the other hand, if it is determined that the stop instruction has not been input, the processing control unit 101 determines whether or not the recording of the current music has ended (step S19). That is, the processing control unit 101 determines whether the track number being reproduced by the disk reproducing device 2 has changed to the next track number.

When it is determined that the recording of the music has not been completed, the process control section 101 returns the process to step S17, and repeats the processes of steps S17 to S19. On the other hand, if it is determined that the recording of the music has ended,
The processing control unit 101 sets “recording OK” to a track in the recording state area 92 corresponding to the music piece whose recording has been completed (step S20). That is, the processing control unit 101
In step S16, "recording OK" is set again on the track on which "recording NG" was temporarily set.

If it is determined in step S17 that a skip has occurred, the processing control section 101 determines whether or not a stop instruction has been input (step S21). That is, the processing control unit 101 determines whether or not an instruction to stop recording has been input by the user via the key input unit 107.

When the processing control unit 101 determines that the stop instruction has been input, the processing proceeds to step S25 described later. On the other hand, if it is determined that the stop instruction has not been input, it is determined whether or not the recording of the current music has ended (step S22). That is, the processing control unit 101 determines whether the track number being reproduced by the disk reproducing device 2 has changed to the next track number.

If the processing control section 101 determines that the recording of the music has not been completed, the processing returns to step S21, and the processing of steps S21 and S22 described above is repeated.
On the other hand, if the process control unit 101 determines that the music has ended, the process proceeds to step S23.

The processing control section 101 sets "recording OK" on the target track in step S20, or
After it is determined in step S22 that the current song has ended, it is determined whether or not recording of all songs has ended (step S23). That is, the processing control unit 101 determines whether or not the recording of all the tracks stored in the reproduction music area 91 has been completed.

When the processing control section 101 determines that the recording of all the music pieces has been completed, the processing advances to step S27 described later. On the other hand, if it is determined that all the songs have not been completed, the processing control unit 101 starts reproduction and recording of the next song (step S24). That is, the processing control unit 10
1 instructs the disk reproducing apparatus 2 to reproduce the next music piece and records the music piece data to be sent to the MD.
When recording of the next song is started, the process control unit 101 returns the process to the above-described step S16, and repeats the subsequent processes similarly.

Further, step S18 or step S21
In step S25, when it is determined that the stop instruction has been input, the processing control unit 101 determines whether or not the music piece whose recording has been stopped is the first music piece. That is, the processing control unit 101
Determines whether the recording of the first music has been completed. This determination is made so that high-speed recording is prohibited for the second and subsequent songs.

If it is determined that the music piece is the first music piece, the processing control section 101 clears the counter value of the timer 106 (step S26). That is, the processing control unit 101 clears the counter value of the timer 106 for prohibiting re-recording for a certain time so that high-speed recording (not re-recording) can be continuously performed. After clearing the counter value of the timer 106, the process control unit 101 ends the recording process. The processing control unit 101 may automatically re-execute the recording process without ending the recording process.

On the other hand, if it is determined that the current track is not the first track, or if it is determined in step S 23 that all tracks have been completed, the processing control unit 101 sets “recording NG” and “unrecorded” in the recording state area 92. The track number of the set track is transferred to the re-recorded music area 93 (step S27). In other words, the process control unit 101 determines a track number that specifies a tune in which a recording error has occurred due to a skip in the disc playback device 2 and a tune that has not been recorded because the user has stopped recording. Is transferred to the re-recorded music area 93 for re-recording.

The processing control unit 101 controls the re-recorded music area 93
Is displayed on the display unit 108 as a recording error track (step S28). For example, the processing control unit 101 displays a message indicating that a recording error has occurred and a recording error track number on the display unit 108.
To be displayed. If nothing is transferred to the re-recorded music area 93, that is, if no skipping occurs, the processing control unit 101 may display a message indicating that the recording has been completed normally.

The processing control section 101 deletes information on the track on which the recording error has occurred from the recorded MD (step S29). That is, the processing control unit 101
The track information that caused the recording error is deleted from the TOC (Table Of Contents).

As described above, when the skipping occurs in the disk reproducing device 2, the processing control unit 101 accurately determines the occurrence of the skipping, and stores information indicating a recording error in the memory 109. When the recording of all songs is completed, the display unit 108 displays the track number of the recording error and the like. Thereby, the user can determine that there is a skip without listening to the recorded music. Also, the track information of the music data in which the recording error has occurred is automatically deleted from the TOC of the MD. As a result, the music data reproduced at high speed can be appropriately recorded at high speed.

Further, a track number for specifying a music piece in which a recording error has occurred is stored in the memory 109 as information to be re-recorded. Then, when re-recording is instructed, the processing control unit 101 records only the music to be re-recorded at a normal speed. Thus, the user can re-record each tune having a recording error only by instructing re-recording via the key input unit 107 without individually specifying the tunes with the recording error. . Then, since a music piece in which a recording error has occurred in high-speed recording is normally recorded, it is possible to reduce the occurrence of skipping or the like and record the music.

Before finishing the recording of the first song,
When the recording is stopped, the processing control unit 101
The counter value of 06 is cleared. Thus, the user can continuously perform high-speed recording without waiting for a certain time.

Next, the above-described recording process will be specifically described with reference to FIG. First, when the user instructs a new recording via the key input unit 107, the processing control unit 1
In step 01, as shown in FIG. 4A, the track number of the music to be reproduced is stored in the reproduction music area 91 (step S12). After initializing the recording state area 92 and the re-recorded music area 93, the processing control unit 101 starts high-speed recording of music data (step S15).

The processing control section 101 sequentially records high-speed music pieces while determining whether or not sound skipping has occurred (step S17). At that time, the processing control unit 101 determines that the processing shown in FIG.
As shown in (1), information indicating the recording state is set in each track of the recording state area 92. Specifically, track 1 (1
No skipping occurred during the recording of track number 2 and
When a skip occurs in (second song), the processing control unit 101
Is the track 1 in the recording state area 92 shown in FIG.
“Recording OK” is set to (first song), and “Recording NG” is set to track 2 (second song).

When the processing control section 101 determines that the recording of all the music pieces has been completed (step S23), as shown in FIG. 4 (c), the "recording N" stored in the recording state area 92.
The track number "G" is transferred to the re-recorded music area 93 (step S27), and the transferred track number is displayed on the display unit 108 as a recording error track (step S2).
8). Then, as shown in FIG. 4D, the processing control unit 101 deletes the information of the tracks 02, 04, and n, which are the tracks of the recording error, from the TOC of the recorded MD (step S29).

When a recording error track or the like is displayed on the display unit 108, the user gives an instruction for re-recording via the key input unit 107. The processing control unit 101 executes the recording process again, and as shown in FIG.
Is transferred to the reproduction music area 91 (step S13). Then, the processing control unit 101
In accordance with the track numbers stored in the reproduction music area 91 shown in FIG. 4E, the normal reproduction of the music is instructed to the disk reproduction device 2 and the normal recording is started (steps S15 to S15).

As described above, when the skipping occurs in the disk reproducing device 2, the processing control unit 101 accurately determines the occurrence of the skipping, and stores information indicating a recording error in the memory 109. When the recording of all songs is completed, the display unit 108 displays the track number of the recording error and the like. Thereby, the user can determine that there is a skip without listening to the recorded music. Further, a track number for specifying a music piece in which a recording error has occurred is stored in the memory 109 as information to be re-recorded. Then, the processing control unit 10
When a re-recording is instructed, 1 records only the music to be re-recorded at a normal speed. Thus, the user can re-record each tune having a recording error only by instructing re-recording via the key input unit 107 without individually specifying the tunes with the recording error. .

In the above embodiment, the recording error track number and the like are displayed on the display unit 108 after the recording of all the music pieces is completed. Good. For example, if it is determined in step S17 in the recording process shown in FIG. 3 that the occurrence of a skip has occurred, the processing control unit 101 displays a message indicating a recording error on the display unit 108. In this case, when the user confirms the displayed recording error message, the key input unit 10
7, it becomes easy to input a recording stop. Hereinafter, a specific description will be given with reference to FIG.

First, as described above, when the user instructs the disk recording device 1 to perform a new recording, the processing control unit 101
Stores the track number of the music to be reproduced in the reproduction music area 91 shown in FIG. 5A (step S12). After initializing the recording state area 92 and the re-recorded music area 93, the processing control unit 101 starts high-speed recording of music data (step S15).

The processing control section 101 sequentially performs high-speed recording while determining whether or not a skip has occurred (step S17). At this time, if the skipping does not occur during the recording of the track 1 (the first tune) and the skipping occurs in the track 2 (the second tune), the processing control unit 101 immediately displays a recording error message on the display unit 108. To be displayed. Then, FIG.
As shown in (2), "recording NG" indicating a recording error is set in track 2 (second song) of the recording state area 92.
Even if the recording error message is displayed, if the user does not input an instruction to stop recording, the processing control unit 101
The processing is continued as it is (steps S21, S22).

When a skipping occurs in track 3 (third tune), the processing control unit 101 displays a recording error message on the display unit 108 again. Then, similarly, the processing control unit 101 sets “recording NG” indicating a recording error in the track 3 (third tune) of the recording state area 92 shown in FIG. 5B. When the user inputs a recording stop instruction via the key input unit 107, the processing control unit 101
Determines that a stop instruction has been input (step S2).
1), the track numbers “recorded NG” and “unrecorded” in the recording state area 92 are transferred to the re-recorded music area 93 shown in FIG. 5C (step S27).

Then, the processing control unit 101 determines whether or not the processing shown in FIG.
As shown in (2), the information of tracks 2 and 3 which are recording error tracks is deleted from the recorded TOC of the MD (step S29). When the user instructs the disk recording device 1 to perform re-recording, the processing control unit 101 executes the recording process again, and is stored in the re-recorded music area 93 as shown in FIG. The transferred track number is transferred to the reproduction music area 91 (step S13).

Then, the processing control section 101 instructs the disk reproducing apparatus 2 to perform normal reproduction of the music having the track number stored in the reproduction music area 91 shown in FIG. 5E, and starts normal recording. (Step S15-).

As described above, when the skipping occurs in the disk reproducing device 2, the processing control unit 101 accurately determines the occurrence of the skipping, and stores information indicating a recording error in the memory 109. Then, a recording error message or the like is displayed on the display unit 108. Thereby, the user can determine that there is a skip without listening to the recorded music, and instruct the disc recording device 1 to stop recording. In addition, a track number that specifies a music piece in which a recording error has occurred due to the stoppage of recording and a music piece that has not been recorded are stored in the memory 109 as information to be re-recorded. When re-recording is instructed, the processing control unit 101 records only the music to be re-recorded at a normal speed. This allows the user to enter the key input unit 1 without individually specifying the music in which the recording error occurred.
By simply instructing re-recording via 07, each music piece in which a recording error has occurred can be recorded again.

In the above embodiment, the recording process is executed again when the user inputs a re-recording instruction.
When a recording error occurs, the recording process may be automatically executed again.

In the above embodiment, the disk recording apparatus for recording music data on an MD has been described. However, the recording target medium is not limited to the MD, but may be another MO (Magnifier).
