  As described above, in an audio device in which a plurality of discs can be mounted and recorded continuously, if there are more discs to be recorded than the number of discs that can be accommodated, all the contained discs are once removed and the discs to be recorded are recorded. It took time and effort to record again, and time was lost.

  In such a case, the present invention provides an audio device that enables a user to take out a disc that has been recorded and mount a new disc to be recorded and to discriminate the newly installed disc and record the disc. Objective.

  In order to solve this problem, an audio apparatus according to the present invention is capable of continuously reproducing a plurality of first recording media for reproduction, and capable of switching the first recording medium during recording, TOC information storage means for storing the TOC information of the first recording medium, recording means for recording the reproduction content of the first recording medium on the second recording medium, TOC information of the first recording medium, Analyzing means for comparing the storage contents of the TOC information storage means, and the recording means compares the TOC information of the first recording medium and the storage contents of the TOC information storage means when they are not the same. The means is allowed to record the reproduction content of the first recording medium.

  The audio apparatus according to the present invention can copy the recorded contents of the plurality of first recording media to the second recording medium by the configuration as described above, and also the TOC information of the first recording medium and the TOC information storage means. Since the recording means is allowed to record only when the stored contents are not the same, in addition to the initially loaded disc, the disc replaced from the middle can be recorded, and duplicate recording or unrecorded tracks can be recorded. There will be no remaining.

(Embodiment 1)
Hereinafter, an audio device according to Embodiment 1 of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of the audio apparatus according to Embodiment 1, and FIG.

  In the audio apparatus of the present embodiment, the reproducing means for continuously reproducing a plurality of CDs that are first recording media sets a plurality of disks 3 on a plurality of trays 2 in the changer 1, and the disks 3 on the tray 2 are set. Can be taken out one by one and set in the reproducing apparatus 4 and information can be taken out by the pickup 5. The reproduced data is recorded by a recording pickup 8 on a recording MD 7 mounted on a recording device 6 as recording means. This recording is controlled by the signal recording control unit 9, and the signal recording control unit 9 is controlled by the system controller 10.

  On the other hand, the TOC information extracted from the disk 3 by the pickup 5 recognizes the TOC information in the disk by the TOC information decoder 11, and stores the TOC information in the disk in the TOC information memory 12 as TOC information storage means. The TOC information analysis unit 13 serving as an analysis unit is controlled by the system controller 10 to read and analyze the contents of the TOC information memory 12. The changer control unit 14 controls the drive of the tray 2 in the changer 1 under the control of the system controller 10.

  Details of the other audio devices are known from the above-mentioned Patent Document 1 and other documents, and detailed description thereof is omitted.

  It is assumed that this apparatus has a function that prevents the same disk from being recorded at high speed for a certain period of time, that is, the total time of the high speed recording track. For this reason, the TOC data of the playback disk during high-speed recording is stored in the TOC information memory 12, and the TOC information analysis unit 13 determines whether or not a certain amount of time has elapsed since recording, and a certain amount of time has elapsed since recording. If the recording has not elapsed, the signal recording control unit 9 does not start recording of the recording medium MD7.

  When the recording of the designated track on the disk 3 on the tray 2 is completed, the system controller 10 issues a command to the changer control unit 14 as to whether or not to replace the disk on the tray.

  The operation of the audio apparatus configured as described above will be described below with reference to the flowchart of FIG. After all the discs once set on the tray 2 of the changer 1 have been recorded in step S1, the disc in the first tray is mounted on the playback device 4 in step S2, the pickup 5 is set, and the disc 3 is set in step S3. The TOC information analysis unit 13 determines whether or not the TOC information is the TOC information of the recorded disc initially set in the TOC information memory 12 in step S4.

  If the TOC information is an unrecorded disc, the newly read TOC information is added to the memory 12, and the disc is recorded in step S5.

  If it is the same as the recorded TOC information in step S4, the number of the tray is checked in step S6. If it is not the final number, the process jumps to step S9 to set the pickup 5 on the disc in the next tray. In step S3, the TOC information of the disc in the next tray is read out. In step S4, the TOC information of the unrecorded disc is checked. In step S6, the changer control unit 14 determines in step S9 until the final tray is recorded. The tray on which the pickup 5 is set on the disk 3 is sequentially replaced.

  If the disc 3 in the last tray has unrecorded TOC information, the process returns from step S7 to step S2, and the same procedure is repeated from the first tray to finally add to the disc set in the tray first. Thus, you can find a disc that was replaced during continuous recording and record continuously.

  As described above, according to the present embodiment, after the recording of the disc on the last tray of the changer is completed, the disc is set again from the first tray to the playback device, and the TOC information of the disc is set in the TOC information memory. Since it is recorded if it is unrecorded while checking whether it is the same as what has already been recorded, in addition to the disk initially set in the changer tray, it was replaced on the changer tray during the continuous recording Discs can be recorded, and there are no duplicate recordings or unrecorded tracks.

(Embodiment 2)
FIG. 3 shows an operation flowchart according to the second embodiment of the present invention. In the second embodiment, it is determined whether or not the playback track time is longer than the remaining recording time of the recording medium MD7. If the playback track time is large, means for stopping recording is added.

  In S4 of the first embodiment, the TOC information analysis unit 13, which is an analysis means, has no recorded TOC information, that is, when there is a track to be recorded, in S10 of FIG. The TOC information is read and the remaining recording time is obtained. In S11, the reproduction track time is obtained from the TOC information read in S3. If the reproduction track time is not larger than the remaining recording time of MD7, the track data of the reproduction disk is obtained in S12. Is recorded in MD7 and the process proceeds to S7 in FIG.

  If the playback track time is longer than the remaining recording time of MD7 in S11, the recording is terminated in S13.

  Thus, according to the present embodiment, in addition to the features of the first embodiment, if the time of the playback track to be recorded is larger than the remaining recording time of the recording medium, the recording is stopped. Recording is not interrupted on the way.

  In each of the above embodiments, the case where a compact disc (CD) is used as the first recording medium for reproduction and a mini disc (MD) is used as the second recording medium for recording is exemplified. These recording media may be recordable, and the first and second recording media may be other recording media as long as they have TOC information.

  Further, although the playback speed of the first recording medium is not particularly mentioned, it is a matter of course that the playback speed is higher than the normal playback speed.

  Further, as a condition for entering the flowchart of FIG. 2 after the end of the disc on the last tray of the changer 1, only when the changer control unit 14 receives a disc replacement instruction after the first recording is started. This prevents unnecessary retrieval of TOC information when there is no disk replacement during recording.

  Furthermore, although explanation is omitted here, it includes a case where only a specific track is selected and reproduced from among a plurality of tracks of the reproduction disc.

  As described above, according to the audio apparatus of the present invention, the recorded contents of the plurality of first recording media can be copied to the second recording medium, and the TOC information of the first recording medium and the TOC information storage means Since the recording means is allowed to record only when the stored contents are not the same, in addition to the disc loaded first, the disc replaced in the middle can also be recorded, duplicate recording or unrecorded tracks remain There is nothing to do.

  Further, the analyzing means compares the remaining recordable time of the second recording medium obtained from the TOC information with the time of the content to be recorded on the first recording medium obtained from the TOC information, and the former is large. Since recording to the second recording medium is permitted only in such a case, there is an industrially advantageous effect that recording does not stop during recording.
