Abstract

본 발명은 스핀들모터(16)에 의해 정속회전하는 상태에서 광자기헤드(17,18)에 의해 정보가 반복적으로 기록/재생되는 광자기디스크(D)를 취급하는 광자기디스크의 재생순서제어장치와 그 방법에 있어서, 모드설정부(10)에 의해 설정되는 상기 광자기디스크(D)의 재생모드하에서 상기 광자기디스크(D)에서 재생되는 정보의 재생빈도를 누산적으로 계수하여 해당 광자기디스크에 기록되도록 함과 더불어 그 재생빈도에 따라 재생순서를 제어하는 제어부(11)와, 상기 제어부(11)의 제어하에 독취되는 상기 광자기디스크(D)에 기록된 재생순서를 기록정보로서 엔코딩처리하고 상기 광자기디스크(D)에 기록된 재생순서를 디코딩하는 엔코딩/디코딩부(14)를 포함하여 구성되고, 상기 제어부(11)는 상기 광자기디스크(D)에 기록된 재생빈도에 따라 재생순서를 결정하여, 해당 광자기디스크(D)의 자동재생시 그 재생빈도에 따라 재생순서가 자동으로 결정되도록 함으로써 빈번한 곡목선택작업이 생략될 수 있도록 한 것이다.The present invention is a reproducing sequence control device for an optical magnetic disk handling an optical magnetic disk (D) in which information is repeatedly recorded / reproduced by the magneto-optical heads (17, 18) in a state of constant rotation by the spindle motor (16). And the method, in which the reproduction frequency of the information reproduced on the magneto-optical disc D is accumulated in the reproduction mode of the magneto-optical disc D set by the mode setting unit 10, and the corresponding magneto-optical magnetism is counted. Encoding is performed as recording information on the control unit 11 for controlling the reproduction order according to the reproduction frequency and the reproduction order recorded on the magneto-optical disc D read out under the control of the control unit 11. And an encoding / decoding section 14 for processing and decoding the playback order recorded on the magneto-optical disc D, wherein the control unit 11 according to the reproduction frequency recorded on the magneto-optical disc D. Determine the playback order , When the optical auto-play of a magnetic disk (D) by making the reproduction order is determined based on the refresh rate is a music piece selecting operation so that the frequency can be eliminated.
