First, after selecting a setup menu (S11), a user inputs a copy key button (S12) among a plurality of menus, and selects copying data of an optical disc to a first recorder (S13).

Thereafter, the data of the optical disk is copied to the first recorder (for example, VCR, HDD), and when the copying is completed (S14), the user selects copying from the first recorder to the optical disk in the copy menu (S15). . At this time, the optical disc recorder performs a series of VCR reproducing operations for reproducing and outputting audio and video signals recorded on a video tape through an interface with a microcomputer of the first recorder.

Thereafter, the operation of the VDR system is controlled, and the audio and video signals reproduced from the videotape are encoded after MPEG encoding, and the buffered audio and video data is copied to the optical disc (S16) and set up by the user. When a finalize selection signal is input from the menu (S17), finalization is performed in the selected mode (S18).

When data is recorded in the VR mode on the rewritable disc in the optical disc recorder as described above, the disc cannot be played back by the recorder means or the playback means which supports only the finalized VR mode or does not support the VR mode, but does record in the video mode. After the finalized optical disc is reproduced, any ordinary optical disc reproducing means can be reproduced.

However, a user who does not know such a problem faces a problem in that an optical disc recorded in the VR mode is not reproduced when it is desired to reproduce it by other reproducing means.

In addition, when copying from the VCR to the optical disc again, the image quality may deteriorate and the time required to reproduce the recorded contents twice is consumed.

When copying to HDD and then copying to optical disc again, the image quality does not deteriorate.However, when copying while playing, it takes time to play twice, and when copying only data without playing, it varies from set to set but it takes more time. There is a problem that is consumed a lot.

The present invention has been made to solve the above problems of the prior art, and an object of the present invention is to copy the data recorded in the VR mode on the rewritable optical disc to the first recorder, and then copy the data back to the optical disc in the video mode. As a result, a method of ensuring reproduction compatibility of a rewritable optical disc with improved compatibility of an optical disc to which data has been copied is provided.

Another object of the present invention is to provide a method of ensuring playback compatibility of a rewritable optical disc that is easy to use and convenient by automatically performing finalization after converting to a video mode without a user's separate operation.

The technical method according to the present invention for achieving the above object is to determine whether the optical disk is an optical disk in the VR mode, and if the optical disk is an optical disk in the VR mode, copy the data of the optical disk to the first recorder, and the first recorder When copying is completed, the optical disk is formatted in video mode. When the format is completed, the optical disk is automatically copied after the data of the first recorder is copied to the optical disk.

The present invention relates to a multi-function device such as DVD / VCR, DVD / HDD, etc., which utilizes the copy function of the first recorder, converts the optical disc into video mode and finalizes the data while preserving data recorded on the optical disc in VR mode. By allowing the recorder to play smoothly, the compatibility of the optical disc can be ensured with a simple operation of the user.

In addition, by automatically processing the optical disc to the video mode and even the finalize operation only by the copy recording operation, it can be conveniently compatible with other optical disc first recorders without a separate user operation.

It also eliminates the hassle and time wasted waiting for the user to complete the write operation to finalize.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The first recorder is composed of a second microphone 22, a head drum 23, and a video tape 24. In addition, in the present embodiment, the second recorder will be described with an example of a DVD recorder and the first recorder with a VCR among VCRs or HDDs.

The optical disc 10 is rotationally driven by the motor 20, and controls the motor driver 19 according to the drive signal generated by the first microcomputer 13, and controls the motor 20 under the control of the motor driver. The optical disk 10 is rotated by driving.

In this case, the optical disc can be rewritten two or more times, and any one of the DVD? RW, DVD-RAM, HD DVD-RW, BD-RE, or CD-RW is used.

The optical pickup 11 includes a laser diode, which irradiates a recording surface of the optical disk 10 with a laser having a power comparable to that of the recording power so as to transmit data transmitted from the VCR system to the optical disk 10. After the data recorded on the optical disc 10 is reproduced (read) by irradiating the optical disc 10 with a laser having a power corresponding to the reproduction power, the read data is copied to the VCR. send.

When the encoder / buffer 12 records data on the optical disc 10, the video / audio data transmitted from the VCR system is encoded and buffered and transmitted to the optical drive unit 15, and the first microcomputer 13 buffers the data. A drive signal is provided to the optical drive section 15 to cause the data to be recorded on the data recording surface of the optical disc 10 to change the recording power of the laser diode.

When the data recorded on the optical disc 10 is reproduced, a laser having a power corresponding to the reproduction power is generated from the laser diode in the optical pickup 11 and irradiated onto the data recording surface of the optical disc 10, and the irradiated laser is applied to the optical disc ( The reflection on the data recording surface of 10) is received by the R / F 16 and then amplified and converted into a binary signal.

The DSP (signal processor 17) restores the binary signal converted by the R / F 16 to digital data. In this case, the restored digital data is in an encoded state, and is then decoded into digital data before encryption while passing through the decoder 18.

The RF signal of the signal processing unit 17 is also supplied to the servo unit 14, which generates a tracking error signal and a focus error signal from the RF signal, and references the tracking error signal and the focus error signal.

Next, when the command for ensuring compatibility of the optical disc is input from the user, it is determined whether the data recorded on the optical disc inserted in the DVD recorder is the data recorded in the VR mode (S22).

At this time, if the data recorded on the optical disc 10 is not the data recorded in the VR mode, a message is output (S24) so that the user can visually identify that the optical disc is not the VR mode in the display means (not shown).

On the other hand, if the data recorded on the optical disc is the data recorded in the VR mode, the microcomputer 22 of the first recorder VCR checks the remaining amount of the VCR through an interface with the DVD recorder.

At this time, if the remaining amount of the VCR is smaller than the recording amount of the optical disc, a message informing the securing of the remaining amount of the VCR is output (S26) so that the user can recognize that the remaining amount of the VCR is insufficient.

On the other hand, if the remaining amount of the VCR is equal to or larger than the data recording amount of the optical disc, the data of the optical disc is copied to the VCR (S25).

Next, after copying the data of the optical disc to the VCR (S27), the optical disc is automatically formatted in video mode (S28).

When the next format is completed (S29), the DVD recorder performs a series of VCR playback operations for reproducing and outputting audio and video signals recorded on a video tape mounted in the VCR via an interface with the microcomputer 22 of the VCR.

That is, the operation of the VDR system is controlled so that the audio and video signals reproduced from the video tape are buffered after being MPEG encoded, and the buffered audio and video data are copied and recorded on the optical disc 10 (S30).

Next, when data copy recording is completed on the optical disk (S31), the first microcomputer 13 automatically performs a finalize operation (S32) without a user's separate key input (S32). The microcomputer 13 reproduces the reproduction management information (TOC information) already recorded on the optical disc 10, and updates the reproduced reproduction management information to the reproduction management information including track information for the additional recorded track data. The first microcomputer records a signal indicating the end of the program (repetitive pulse of 2 Hz) in the lead-out area of the optical disc 10, thereby completing the finalizing operation. You're all done.

If the VCR reproducing operation is completed during the series of copy recording operations, and the user inputs the reproduction stop key, the copy recording operation is stopped.

Accordingly, by utilizing the copy function of the first recorder, the optical disc is converted to the video mode while preserving the data recorded on the optical disc in the VR mode, and then finalized so that it can be played smoothly in other recorders. Compatibility can be secured.
