BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synchronous recording method in a double disc recorder, and more particularly, in a double disc recorder in which a first optical disc device and a second optical disc device are integrally read and read from a read-only optical disc such as a CD-ROM. When dubbing and recording audio data to be recorded on a recordable optical disc such as a CD-RW or CD-R, a synchronous recording is provided so that a silent section can be separately recorded between the audio songs to be copied and recorded ( Sync Recording) apparatus and method.

First, Fig. 1 shows a configuration of a general double disc recorder, in which the first disc apparatus 100 for reproducing an optical disc for reproduction, such as a CD-ROM, and a CD-RW. Alternatively, the second disk apparatus 200 for reproducing or recording a recordable optical disc such as a CD-R or the like is integrally configured to read and reproduce audio data read and reproduced from a reproduction-only optical disc such as the CD-ROM. Copy recording on a recordable optical disc such as

On the other hand, the first disk apparatus 100 includes an optical pickup 11 for reading data recorded on the optical disk 10; A reproduction signal processing unit (12) for processing a reproduction signal of the read data; A control unit (13) for controlling operation of the configuration means according to a user key input requested through a key input unit (14); And a D / A converter 15 for converting and outputting audio data processed by the reproduction signal processing unit into an analog audio signal.

The second disk apparatus 200 includes an optical pickup 21 for reading or recording data recorded on the optical disk 20; A recording / reproducing signal processor 22 for processing the read data into a reproduction signal or processing an input signal into a signal suitable for recording; A control unit 23 for controlling recording and playback signal processing operations in accordance with a user key input requested through the key input unit 24; An A / D converter 26 for converting an analog audio signal input from the outside into a digital audio signal; And a D / A converter 25 for converting and outputting audio data processed by the recording / reproducing signal processing unit into an analog audio signal, wherein the control unit 13 of the first disk device is provided. The control unit 23 of the second disk device may be connected to each other to simultaneously perform playback and recording operations in response to a user's request, or to independently play each optical disk inserted and seated in the first and second disk devices. Control.

Therefore, a user having a double disc recorder configured as described above may include an optical disc 10 such as a CD-ROM and an optical disc such as a CD-RW in the first and second disk apparatuses 100 and 200. After inserting and seating 20, the first disk device 100 is set to a playback mode, and the second disk device 200 is set to a recording mode, such that the optical disk 10 such as the CD-ROM or the like. Audio data recorded in the above can be copied and recorded on the optical disc 20 such as the CD-RW or the like.

On the other hand, in the case where the copy recording operation is performed, the controller 23 of the second optical disk apparatus 200 may include table of contents information of the reproduction-only optical disk transmitted from the controller 13 of the first optical disk apparatus 100. After receiving and storing (TOC: Table of Contents) in the internal memory (not shown), the start address (Start_Address) and the end address (End_Address) for each track recorded in the table of contents information are detected.

As shown in FIG. 2, the audio data CD_Audio In received and recorded is classified and recorded in track units corresponding to each audio song according to the identified end address of each track. Between each track recorded in 10), there may be a silent section of about 3 seconds, or the silent section may not exist so that the user can easily recognize the end and start of the audio song. .

However, in the control unit 23 of the second optical disc, as shown in Fig. 2, new tracks are separately set according to the end address (End_Address) for each track recorded in the table of contents information of the optical disc 10 for reproduction only. Since audio data (CDP_Audio In) to be transmitted and received is separated and recorded in track units, audio data to be copied and recorded on the recordable optical disc 20, that is, time data for a silent section does not exist between tracks. Will not.

As a result, when the user selects and plays a specific audio song, the silent section existing in the first section of the track corresponding to the audio song is unnecessarily reproduced. After about three seconds, the actual audio data is reproduced. The output problem occurs.                         

In addition, since the playback time for each track further includes a time of about 3 seconds corresponding to the silent section, a problem occurs that the playback time for each track becomes incorrect.

Accordingly, the present invention has been made to solve the above problems, and in the double disc recorder in which the first optical disc device and the second optical disc device are integrally combined, audio data read and reproduced from a read-only optical disc such as a CD-ROM, etc. In the case of copy recording on a recordable optical disc such as a CD-RW or CD-R, a new track is recorded after recording a silent section having a predetermined recording size based on the start address for each track recorded in the table of contents information of the reproduction-only optical disc. To record audio data, and to terminate the track on the basis of the end address of each track, thereby synchronizing recording in a double disc recorder such that a silent section is normally recorded between audio tracks recorded on a recordable optical disc. The purpose is to provide a method.

In the synchronous recording method of the double disc recorder according to the present invention for achieving the above object, the recording position address of the currently reproduced audio data is the start address of the track in a state where the recording operation is suspended when a copy recording request is made. Detecting and confirming whether or not coinciding with; A two-step recording of a silent section of a predetermined recording size on a recordable optical disc when the result of the check is matched; Recording and recording the audio data into a new track after recording the silent section; During the recording, if the recording position address of the currently reproduced audio data coincides with the end address of the track, terminating the track; And five steps of repeating the operation according to whether or not the recording position address of the reproduced audio data corresponds to the start address of the next track after the end of the partition.

Hereinafter, a preferred embodiment of a synchronous recording method in a double disc recorder according to the present invention will be described in detail with reference to the accompanying drawings.

First, in the synchronous recording method of the double disc recorder according to the present invention, as described above with reference to FIG. 1, the first optical disc apparatus 100 and the second optical disc apparatus 200 include an optical disc such as a CD-ROM or the like. 10) and the optical disk 20 such as a CD-RW, respectively, are inserted and seated therein, and then the first optical disk device 100 is set to a playback mode, and the second optical disk device 200 is set to a recording mode. When copying and recording audio data recorded on the optical disc 10 such as a CD-ROM onto the optical disc 20 such as the CD-RW, etc., this operation is automatically performed, and will be described in detail with reference to the operation flowchart shown in FIG. 3. Is as follows.

First, when a key input requesting copy recording is selected and input from a user having a double disc recorder (S10), the control unit 23 of the second optical disc apparatus holds the data recording operation in a state where the data recording operation is suspended. 1 to interface with the control unit 13 of the optical disk device to read and transmit the table of contents information (TOC) recorded in the lead-in area of the read-only optical disk 10 inserted and seated in the first optical disk device. You will be asked.

On the other hand, the control unit 13 of the first optical disk apparatus searches and reads the table of contents information recorded in the lead-in area of the read-only optical disk or reads the table of contents information stored in the internal memory (not shown) according to the request. Thus, the control unit 23 transmits the data to the control unit 23 of the second optical disk device.

Then, the control unit 23 of the second optical disk apparatus stores the table of contents information of the transmission-only optical disc for transmission and reception in an internal memory (S11), and then reads and reproduces data from the reproduction-only optical disc 10. Allow the playback operation to be performed.

Thereafter, the audio data transmitted and received by the reproduction operation is temporarily stored in a RAM memory provided in the second optical disk apparatus (S12), and the recording address of the audio data currently read and reproduced is stored in the table of contents information. It is detected whether or not it corresponds to a start address for each track included and recorded (S13).

For example, as shown in FIG. 4, in the control unit 23 of the second optical disc apparatus, the recording address of the audio data currently reproduced through the interface with the control unit 13 of the first optical disc apparatus is the first. It is detected whether it corresponds to the start address (Start_Add 1) of the track.

As a result of the detection, in the case of the start address of the first track, null data having a recording size of a predetermined recording size, for example, a reproduction time of about 3 seconds is transmitted to the recordable optical disc 20. After recording in the silent section Pause 0 '(S14), a new first track (Track 1') is set (S15), and a recording operation for recording the temporarily stored audio data is performed (S16).

On the other hand, during the audio data recording operation, as shown in FIG. 4, when the end address of the first track is detected (S17), the recording audio data is divided into tracks corresponding to one audio song. (S18).

Thereafter, since the silent section recording and track setting and the audio recording operation are repeatedly performed until the copy recording is requested to be interrupted or the copying is completed, the recordable optical disc as shown in FIG. Prior to the first track (Track 1 ') and the third track (Track 3'), which are copied and recorded on 20), unlike the reproduction-only optical disc 10, silent sections of a predetermined recording size (Pause 0 ', Pause 2') This recording is inserted, and before the second track (Track 2 ') and the fourth track (Track 4'), silent sections of a predetermined recording size are recorded as in the optical disk 10 for reproduction only.

Accordingly, when any one track, e.g., the second track (Track 2 '), which has been copied and recorded on the recordable optical disc 20 is selectively reproduced, the first recording position of the second track is searched and recorded. Since audio data is read out and reproduced, it is possible to prevent the silent section from being unnecessarily read out and reproduced.

The audio data recorded in each track of the recordable optical disc 20 is the same as the audio data recorded in each track of the read-only optical disc 10, so that the playing time for each track is exactly the same.

Further, when continuously playing a plurality of tracks copied and recorded on the recordable optical disc 20, for example, when continuously playing the third track from the first track, a predetermined recording size existing between the tracks Since the silent section is read out and reproduced, a plurality of audio songs continuously reproduced can be easily listened to.

As mentioned above, preferred embodiments of the present invention are disclosed for purposes of illustration, and those skilled in the art can improve and change various other embodiments within the spirit and technical scope of the present invention disclosed in the appended claims below. , Replacement or addition would be possible.

In the synchronous recording method of the double disc recorder according to the present invention as described above, the double disc recorder in which the first optical disc device and the second optical disc device are integrally read is read and reproduced from a read-only optical disc such as a CD-ROM. When dubbing audio data to a recordable optical disc such as a CD-RW or CD-R, recording a silent section having a predetermined recording size based on the track start address recorded in the table of contents information of the reproduction-only optical disc. After that, new audio is set to record audio data, and the track is partitioned based on the end address of each track, whereby a silent section is normally recorded between audio tracks recorded on the recordable optical disc, thereby allowing specific audio to be recorded. When you select and play back songs, silence sections are played unnecessarily, or corresponding audio songs. It becomes possible to prevent the reproduction time to be inaccurate, it is also very useful to be able to separate inventions listen to each of the audio track by a silent interval in the case of performing the continuous reproduction operation.
