Abstract

본 발명은 디스크를 음악의 종류별로 분할하여 장착함으로써 프로그램 기능을 사용치 않고도 원하는 디스크의 음악을 반복하여 재생할 수 있는 멀티-체인지 CDP의 음향재생방법 및 장치이다. 이 멀티-체인지 CDP의 음향 재생방법은 외부에서 키를 입력하는 키입력과정과, 키입력과정에서 입력된 키가 분할된 디스크의 키인지 일반 키인지를 비교하는 키비교과정과, 키비교과정에서 비교된 키가 분할된 디스크의 키일때 분할키에 해당하는 디스크의 번호를 설정하는 분할키 설정과정과, 분할키 설정과정후 인가되는 키에 해당하는 동작을 수행하는 키수행과정과, 키수행과정후 분할키 설정과정에서 설정된 디스크를 재생하는 재생과정으로 이루어진다. 그리고 멀티-체인지 CDP의 음향재생장치는 디스크를 음악의 종류별로 분할하여 장착한 디스크장착장치와, 키입력부와, 제어부와, 서브회로와, 픽업장치와, 신호처리부 및 출력부로 구성하여 원하는 디스크만 반복하여 재생 가능함으로써 좀더 간편하게 음악을 감상할 수 있다.The present invention is a method and apparatus for reproducing a sound of a multi-change CDP, by dividing and mounting a disc for each type of music, thereby repeatedly playing a desired disc without using a program function. The sound reproduction method of the multi-change CDP includes a key comparison process for comparing an external key input process, a key comparison process for comparing whether a key input in a key input process is a key of a partitioned disk or a general key, and a key comparison process. When the compared key is a partitioned disk key, a partitioning key setting step of setting a disk number corresponding to the partitioning key, a keying step of performing an operation corresponding to an authorized key after the partitioning key setting step, and a keying step Thereafter, a playback process of playing the disc set in the partitioning key setting process is performed. The sound reproducing apparatus of the multi-change CDP is composed of a disc mounting apparatus that divides and mounts discs according to the type of music, a key input unit, a control unit, a subcircuit, a pickup unit, a signal processing unit, and an output unit. You can listen to music more easily by playing it repeatedly.

Claims

In a multi-change CDP in which a plurality of discs provided are divided into types of music and mounted on a disc mounting apparatus, a key input process for inputting a key from outside, and a key of a disc in which a key input in the key input process is divided. A key comparison process for comparing whether the key is a normal key, a partition key setting process for setting a disk number corresponding to the partition key when the key compared in the key comparison process is a partitioned key, and setting up the partition key And a reproducing process of reproducing a disc set in said partitioning key setting process after performing said keying process.

The multi-change CDP sound reproducing method according to claim 1, wherein if there is no externally applied key after the reproducing process for reproducing the set disc, the key performing process and the reproducing process are repeated.

A disk mounting apparatus which divides and fixes a disk according to the type of music, a key input means, a control means, a servo circuit driven under the control of the control means, and a signal recorded on a disc controlled by the servo circuit is detected. And a pickup means, signal processing means for processing a signal detected by said pick-up means under the control of said control means, and an output means for outputting said processed sound signal.
