씨디롬 드라이브를 이용한 엠피3 씨디 플래이어 제작방법{MAKING MP3 CD PLAYER WITH COMPUTER CD-ROM DRIVE}How to make MP3 CD player using CD-ROM drive {MAKING MP3 CD PLAYER WITH COMPUTER CD-ROM DRIVE}

본 발명은 컴퓨터 음성파일 형식인 MP3 파일이 담긴 CD-ROM을 재생할 수 있는 MP3 PLAYER의 제작에 관한 것이다.The present invention relates to the production of an MP3 player that can play a CD-ROM containing MP3 files in the form of computer voice files.

MP3파일은 음악압축파일로서 수준높은 품질의 사운드를 DISK용량을 대량으로 차지하지 않고도 손쉽게 저장할 수 있도록 고안된 음성 압축파일 형식이다. 이러한 MP3파일은 일반적으로 컴퓨터에서 사운드 재생 프로그램을 통해 재생하여 왔다. 또한, MP3파일은 CD 혹은 DISK, 그리고 MEMORY등의 저장형식을 통해 저장되어 연속 재생되는 형식의 음악파일이다. 이러한 MP3파일의 재생을 위하여는 컴퓨터를 이용하거나, 별도의 MP3 PLAYER가 필요한 데, 기존의 MP3 PLAYER의 경우 MEMORY를 장착하여 한정된 MEMORY의 용량에 의존하여 재생될 수 있었다. 물론 MEMORY를 사용할 경우 휴대용으로 사용할 수 있는 장점이 있지만, 용량의 제한 및 비싼 MEMORY가격으로 인하여 점차 MP3 파일을 CD-ROM DISK에 저장해서 CD-ROM DISK를 MP3 PLAYER가 실행시킴으로써 DISK의 용량만큼 수 십곡에서 수 백곡에 이르기까지 재생할 수 있는 단계에 이르렀다. 이러한 형태가 MP3 CD-PLAYER인 것이다. 이 역시 외장형으로 손쉽게 휴대할 수 있는 크기를 지닐 수 있도록 개발되고 있으나, CD DISK의 크기가 제한되어 있기 때문에 소형화에 어렵고, 소형화할수록 그 비용이 비싸지는 단점이 있다. 그러나, 이와는 달리 똑같이 CD DISK에 MP3를 저장해 두고 재생하는 방식이지만, 컴퓨터에 부착된 CD-ROM DRIVE를 이용하여 컴퓨터에 내장된 MP3 파일 재생 S/W를 활용하여 컴퓨터를 통해 MP3파일을 재생하는 방법이 있다. 상기에 언급된 시중의 MP3 CD PLAYER의 경우 일반 CD-PLAYER에 MP3 디코더를 장착하고, AUDIO기기로서의 몇가지 제어 장치부를 추가함으로써 가능해 진 것이었다. 그러나, 그 비용이 적지않다는 단점이 있었다.MP3 file is a music compression file format that is designed to store high quality sound easily without taking large amount of DISK capacity. Such MP3 files have generally been played by sound playback programs on a computer. In addition, MP3 files are music files in a format that is continuously played by being stored through a storage format such as CD, DISK, and MEMORY. In order to play the MP3 file, a computer or a separate MP3 player is required. In the case of the existing MP3 player, the MP3 player can be played depending on the limited capacity of the memory by mounting a memory. Of course, if you use MEMORY, you can use it as a portable device.However, due to the limitation of capacity and expensive memory price, you can save MP3 files to CD-ROM DISK and execute CD-ROM DISK by MP3 PLAYER. It has reached the stage where it can play from several hundred songs. This type is the MP3 CD-PLAYER. This is also developed to have a size that can be easily carried as an external type, but because the size of the CD DISK is limited, it is difficult to miniaturize, the disadvantage is that the more expensive the smaller. However, unlike this method, MP3 files are stored in CD DISK and played back.However, MP3 files can be played through computer using MP3 file playback software built in computer using CD-ROM DRIVE attached to computer. There is this. The commercial MP3 CD player mentioned above was made possible by attaching an MP3 decoder to a general CD-player and adding some control units as audio devices. However, there is a disadvantage that the cost is not small.
