In step ST2, it is determined whether or not the reproduction of the music by the disk reproducing device 10 is continuous without generating any skip using the determination signal LP. The discrimination regarding the continuity of the reproduction of the music is performed by, for example, a CD-DA
This can be performed by determining whether or not the time information of the subcodes recorded on the disc 100 is continuous by the CD control unit 25 and generating the determination signal LP.
Here, when it is determined that the reproduction of the music is continuously performed, the process proceeds to step ST3.

In step ST3, it is determined whether or not the reproduction of the music to be dubbed has been completed. If the reproduction of the music to be dubbed has not been completed, step ST2
When all are completed, the process proceeds to step ST4.

In step ST4, the reproducing operation of the disk reproducing unit 10 is terminated. Further, the disc recording / reproducing device section 40 records TOC information indicating the recording position of the music recorded on the CD-RW disc 200 in the lead-in area of the CD-RW disc 200, and performs the recording operation of the disc recording / reproducing device section 40. To complete the dubbing process.

On the other hand, when it is determined in step ST2 that the reproduction of the music is not continuous due to skipping of sound, the process proceeds to step ST5. In step ST5, the recording operation of the disk recording / reproducing device section 40 is set to a pause state, and the process proceeds to step ST6.

In step ST6, the reproduction position in the disk reproducing device 10 is skipped to the beginning of the next music piece, and the process proceeds to step ST7. In step ST7, the track number in the disk recording and reproducing device 40 is updated. The recording operation is restarted, and the process returns to step ST2.

As described above, according to the above-described first operation,
The desired music is reproduced in the order shown in FIG.
When dubbing to the RW disc 200, the song "TN
When “3” is no longer continuously reproduced, as shown in FIG. 3B, a new tune “TN4” can be switched from the position where continuous reproduction is stopped, and the tune can be recorded continuously.

By the way, when a sound skip occurs due to vibration or the like, there is a case where the music in which the sound skip occurs can be continuously reproduced by repeating the reproducing operation.
Therefore, as a second operation, the CD-DA disk 10
When the music recorded in the CD-RW disc 2 cannot be reproduced continuously, the music is reproduced again and the CD-RW disc 2 is reproduced.

Proceed to 12.

In step ST12, it is determined whether or not the number of repetitions of the reproduction of the music in which the skipping has occurred is greater than a predetermined number N. If the number of repetitions is not greater than the predetermined number N, the process proceeds to step ST13. If the number of repetitions is greater than the predetermined number N, the process proceeds to step ST4.

In step ST13, the reproduction position of the disk reproducing device 10 is returned to the head position of the music in which the sound skipping has occurred, and the process proceeds to step ST14.

This case will be described with reference to the flowchart of FIG. In FIG. 5, processes corresponding to those in FIG. 2 are denoted by the same step numbers, and in FIG.
If it is determined in step 2 that the reproduction of the music is not continuous, the process proceeds to step ST21 as shown in the figure, where the recording operation in the disk recording / reproducing device section 40 is temporarily stopped, and the recording position is skipped. It returns to the head position of the music and proceeds to step ST22.

In step ST22, the reproduction position in the disk reproducing device section 10 is skipped to the head position of the music following the music in which the skipping occurred, and the process proceeds to step ST23.
In step ST23, the recording operation of the disk recording / reproducing device section 40 is restarted, and the process returns to step ST2.

As described above, the disc reproducing device 10 skips the reproduction of the music having the skipped sound, and the disc recording / reproducing device 40 records the next music at the recording position of the music having the skipped sound. Therefore, when skipping occurs due to a scratch on the disc or the like, as shown in FIG.
Dubbing can be correctly performed on the W disk 200.

Further, the fourth operation shown in the flowchart of FIG. 6 may be performed by combining the above-described second operation and third operation.

In FIG. 6, when it is determined in step ST2 that the reproduction of the music is not continuous, the process proceeds to step ST31 as shown in FIG. 6, and the recording operation in the disk recording / reproducing device section 40 is temporarily stopped. Return the recording position to the beginning position of the music in which the skipping occurred, and step ST
Go to 32.

In step ST32, it is determined whether or not the number of repetitions of the reproduction of the music piece whose reproduction is not continuously performed has exceeded a predetermined number N. Here, if the number of repetition times of reproduction is not larger than the predetermined number N, step ST33
Then, the playback position in the disk playback device unit 10 is returned to the head position of the music in which the skipping occurred, and the process proceeds to step ST35. When the number of repetitions of reproduction is larger than the predetermined number N, the process proceeds to step ST34, where the reproduction position in the disc reproducing device unit 10 is returned to the head position of the music in which the skipping occurred, and the process proceeds to step ST35. Step ST3
In step 5, the recording operation of the disk recording / reproducing device section 40 is restarted, and the process returns to step ST2.

In this case, when a sound skip occurs due to vibration, a scratch on the disk, or the like, the music that cannot be continuously played back even if the repetitive playback operation is performed is automatically removed, and only the desired music is correctly removed. It can be recorded on a CD-RW disc 200.

In the above-described embodiment, the operation control section 90 controls the disk reproducing apparatus section 10 and the disk recording / reproducing apparatus section 40. However, a terminal for outputting a reproduction signal of the disk reproducing apparatus section 10 is provided. The terminal for inputting the recording signal of the disk recording / reproducing device section 40 is connected, and the CD control section 25 and the CD-RW control section 55 perform communication to perform the above-described first to fourth operations. This may be performed by the unit 40.

In addition to dubbing music recorded on the CD-DA disc 100 to the CD-RW disc 200, a recording medium using another recording medium can be used as long as the continuity of reproduction can be confirmed. The signal from the reproducing device may be dubbed to the CD-RW disc 200.
