Abstract

본 발명은 광디스크시스템에 있어서 한번의 키조작으로 연속적인 서치를 하기 위한 원터치 연속서치방법에 관한 것이다. 이를 위하여, 동작모드에 따른 키를 입력하기 위한 키입력수단과, 키입력수단에서 입력되는 동작모드에 따라서 각종 서보 중 해당하는 서보가 구동될 수 있도록 구동제어신호를 발생하기 위한 제어수단과, 동작모드가 수행되는데 필요한 모터를 구동하기 위한 전압 또는 전류신호 형태의 제어신호를 발생시키기 위한 서보수단과, 서보수단에서 출력되는 제어신호에 따라서 모터를 구동하기 위한 모터구동수단을 구비한 광디스크시스템의 원터치 연속서치방법에 있어서, 상기 키입력수단을 통해 서치버튼이 눌러진 횟수에 따라 어떤 동작모드인지를 판단하기 위한 모드판단과정과, 정상 서치모드로 판단된 경우 서보수단에 정상 서치모드에 필요한 데이타와 클럭을 전송하기 위한 정상 서치모드 제어과정과, 고속 서치모드로 판단된 경우 서보수단에 고속 서치모드에 필요한 데이타와 클럭을 전송하기 위한 고속 서치모드 제어과정과, 순방향 또는 역방향의 정상 또는 고속 서치모드에 따라서 모터구동수단에 해당하는 전류를 공급하기 위한 전류 공급과정과, 전류공급과정에서 공급되는 전류를 따라서 모터를 구동하여 정상 또는 고속 서치모드를 수행하기 위한 서치모드 수행과정으로 구성한다. 따라서 한번의 키조작으로 서치작업을 용이하게 수행할 수 있는 이점이 있다.The present invention relates to a one-touch continuous search method for continuous search by one key operation in an optical disk system. To this end, key input means for inputting a key according to an operation mode, control means for generating a drive control signal to drive a corresponding servo among various servos according to an operation mode input from the key input means, and operation One-touch of an optical disc system having servo means for generating a control signal in the form of a voltage or current signal for driving a motor required for the mode to be executed, and motor driving means for driving the motor in accordance with a control signal output from the servo means. In the continuous search method, a mode determination process for determining the operation mode according to the number of times the search button is pressed through the key input means, and if it is determined that the normal search mode, the data required for the normal search mode and the servo means; The normal search mode control process for transmitting the clock, and if it is determined that the high-speed search mode In the high-speed search mode control process for transmitting data and clock required in the fast search mode, in the current supply process for supplying the current corresponding to the motor driving means in the normal or high-speed search mode in the forward or reverse direction, and in the current supply process. It consists of a search mode execution process for performing a normal or high-speed search mode by driving a motor according to the supplied current. Therefore, there is an advantage that the search operation can be easily performed with one key operation.
