Description

Portable disk apparatus having read and writing function

The present invention relates to a disc recording and reproducing apparatus capable of recording data on a disc or reproducing data recorded on a disc, and more particularly, a portable disc recording and reproducing apparatus capable of recording and reproducing data of various formats on a small disc. It is about.

In general, MP3 stands for 'Moving Picture Experts Group (MPEG) Layer-3', and the MP3 storage method is a method of compressing and storing data using a perceptual sensing coding technology called 'Layer-3'. Using the MP3 compression technology, the capacity of data that can be stored on a single compact disk is 10 to 20 times larger than the capacity of data that can be stored without using compression technology. You can play music with high quality sound.

Conventional MP3 storage disc reproducing apparatus generally has a size that can use a compact disc of 12 cm in diameter, but as a small compact disc of 8 cm in diameter is produced, the disc reproducing device is spread to a small size accordingly. It is used.

However, the MP3 storage disc playback device using such a small disc only has a function of playing data stored on the disc, and the MP3 file is stored in the built-in flash memory and played back through a decompressing decoder. Flash memory used in the MP3 player is very expensive, and furthermore, since the memory can not be replaced, there is a problem that the capacity of the data that can be stored is limited.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is possible to record and play back various types of audio data and general data such as MP3, WMA, AAC, WAV, etc. by using a small disk having a diameter of 8 cm or less, as well as a PC. It is an object of the present invention to provide a portable disc recording and reproducing apparatus for outputting data to an external device such as an external device.

Another object of the present invention is to input audio from an external device using the advantage of being able to record data in various file formats on a rewritable CD (CD-RW) or DVD (Digital Video Disk). The present invention provides a portable disc recording and reproducing apparatus having a storage function by storing data and general data without limitation of capacity.

Still another object of the present invention is to provide a portable disc recording and reproducing apparatus having a recording function by installing a microphone inside the portable disc recording and reproducing apparatus according to the present invention and storing the audio data inputted from the microphone.

In order to achieve the above objects, the portable disc recording and reproducing apparatus having the function of reproducing and storing a small disc according to the present invention is as follows.

That is, the portable disc recording and reproducing apparatus according to the present invention uses a size smaller than 8 cm in diameter and a small disc capable of recording data of various file formats, which is smaller than that of a conventional disc. By miniaturizing and linking an external device such as a PC, various types of audio data and general data such as MP3, WMA, AAC, and WAV can be stored in a small disk.

In addition, by installing a microphone inside the portable disk recording and playback device, it is possible to store audio data input through the microphone on the disk.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment according to the present invention.

1 is a block diagram of a portable disc recording and reproducing apparatus according to the present invention.

As shown in FIG. 1, the portable disc recording and reproducing apparatus 10 includes a data transmitting and receiving unit 11, an audio input / output unit 12, a coding and decoding unit 13, a transmitter 14, and a pick-up. up) 15, receiver 16, and disk 17.

The data transmission / reception unit 11 processes data transmission and reception between the small disc playback device and an external device (for example, a PC), and the coding and decoding unit 13 receives data input from the external device via the data transmission / reception unit 11. It converts and compresses the data suitable for the disc (digital form) or reverse converts and decompresses the data extracted from the disc into the format suitable for the external device.

In addition, the transmitter 14 controls the coded data and transmits the power to the pickup 15 when the power is supplied, and the pickup 15 writes the transmitted data to a disk or reads the data from the disk as an electrical signal. Convert

In addition, the receiver 16 amplifies and filters the electric signal converted by the pickup 15, and converts it into a form that is easy to extract data. The audio input / output unit 12 passes through the receiver 16, and the coding and decoding unit 13 ) Outputs the decoded audio data to an external device (eg, a speaker of a headset), and transmits an audio signal input from the external device (a microphone of the headset) to the coding and decoding unit 13.

In addition, the disk 17 is a data storage medium such as a compact disk, CD-RW, or DVD.
