BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recordable CDP (Compact Disk Player), and more particularly to a recordable CDP and a data editing method using a general-purpose computer for editing data to be recorded on a recordable CD by using an auxiliary storage device of a general-purpose computer. .

Generally, recordable CDP that can record data only once can't correct or erase wrong recorded data when user records wrong or unwanted data or serious error occurs in the data being recorded by external impact. This can lead to disc writes.

As a countermeasure to prevent such cases, conventional recordable CDPs use DAT (Digital Audio Tape) to edit data to be recorded on recordable CDs first in the DAT, and then record the edited data to recordable CDs. Has been taken to copy. However, since the DAT used in such a method is not widely used as an expensive medium, it is difficult to be generalized.

Accordingly, the present invention provides a general-purpose computer capable of easily editing data to be recorded using a HDD (Hard Disk Drive), which is an auxiliary memory device of a general-purpose computer, in a recordable CDP, and recording desired data on a recordable CD without a false record. Its purpose is to provide a recordable CDP and data editing method using

In order to achieve the above object, the present invention provides an A / D converter for converting an input analog signal into a digital signal, an encoder for encoding an input signal, and a signal supplied from the encoder to a disk, and the data recorded on the disk. A recording / reproducing unit for reproducing a signal, a decoder for decoding a signal supplied from the recording / reproducing unit, a D / A converter for converting an input digital signal into an analog signal, and a signal supplied from the D / A converter. A recordable CDP including a speaker for outputting sound; In a recordable CDP using a CUP and a general-purpose computer having a general-purpose computer including an HDD, a buffer for adjusting data differences and data types between the recordable-CDP and the general-purpose computer to exchange data between the recordable CDP and the HDD. And a first switch for transmitting a signal supplied from the A / D converter to the buffer or encoder under control of the CPU, and a signal supplied from the buffer to the encoder or D / A converter under control of the CPU. And a third switch for transmitting a signal supplied from the A / D converter to the D / A converter converter under the control of the CPU.

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

1 is a block diagram of a recordable CDP using a general-purpose computer according to the present invention. The analog sound signal Si input through the input terminal is converted into a digital sound signal by the A / D converter 10 and supplied to the first switch SW1. The first switch SW1 is connected to be transferred to the buffer 20 to be stored in the HDD 34 under the control of the CPU 32 embedded in the general-purpose computer 30, or recorded on the CD. Connected to the encoder 40 to be transmitted. In addition, the digital sound signal output from the A / D converter 10 or the digital sound signal directly input from the outside is supplied to the D / A converter 70 via the third switch SW3 and converted into an analog sound signal. The sound is output through the speaker. At this time, the third switch SW3 is turned on / off under the control of the CPU 32.

When the input sound signal is edited using the auxiliary storage device of the general-purpose computer, the CPU 32 allows the a and b terminals of the first switch SW1 to be connected to each other via the A / D converter 10 or externally. Digital sound signals input directly from the buffer 20 are transmitted to the buffer 20. The buffer 20 adjusts the difference between the clock frequency used in the CDP and the clock frequency used in the general purpose computer so that data exchange is possible between the CDP and the general purpose computer. Thus, the sound signal is input to the HDD 34 of the general purpose computer via the buffer 20. Since the HDD 34 has a sufficient storage capacity of several tens of megabytes, there is no problem in storing sound data of a few minutes. In this case, the user may store the sound signal in the HDD 34 and hear the sound directly through the speaker 80. That is, when the third switch SW3 is connected by the control of the CPU 32, the sound signal stored in the HDD 34 via the buffer 20 through the first switch SW1 is simultaneously transmitted through the third switch. The sound is outputted through the D / A converter 70 to the speaker 80. Therefore, the user can listen to the sound signal input to the CDP through the speaker 80 and simultaneously store the sound data in the HDD 34 of the general-purpose computer, and also monitor the sound data stored in the HDD 34 DP (not shown). Audio data that you don't want to record can be deleted so that you can edit the data more efficiently. In this way, since the editing is efficiently performed, sound data is recorded on the recordable CD, so that only desired data can be recorded, and erroneous recording can be sufficiently prevented.

The edited sound data can be recorded on a recordable CD or directly heard through the speaker 80. When the sound data stored in the HDD 34 is in the mode of being recorded on the recordable CD, the second switch SW2 is connected to the d terminal and the e terminal by the control of the CPU 32. Therefore, the sound data read out from the HDD 34 is supplied to the encoder 40 via the buffer 20. The sound signal encoded by the encoder 40 is recorded on the recordable CD by the recording / reproducing section 50. The sound signals recorded on the CD are reproduced by the recording / reproducing unit 50 and converted into analog sound signals by the D / A converter 70 via the decoder 60 and then output as sound through the speaker 80. . On the other hand, when the user wants to directly listen to the sound data recorded on the HDD 34, the second terminal SW2 is connected to the terminal d terminal under the control of the CPU (32). Then, the sound data stored in the HDD 34 is transmitted to the D / A converter 70 through the buffer 20 to be converted into an analog sound signal and then output as sound through the speaker 80.

As described above, the recording mode of the recordable CDP is controlled by the CPU 32 built in the general-purpose computer, and the sound data is edited by storing the data in the HDD 34 while listening to the input sound signal. A mode for reading and listening to sound data stored in the HDD 34 and listening through the speaker 80, and monitoring and monitoring through a monitor, and for recording the edited sound data from the HDD 34 and recording them on a recordable CD. And a playback mode for reproducing the sound signal recorded on the recordable CD and outputting the sound from the speaker.

As described above, the write-once-type CDP and data editing method using a general-purpose computer according to the present invention edit data by using an auxiliary storage device of a general-purpose computer which is common in editing of data to be recorded on a recordable CD. And not only can the search be easily and efficiently performed, but the data can be prevented from being erroneously recorded on the CD.
