Abstract

본 발명은 광 디스크 기록 매체 및 그 재생 방법에 관한 것으로, 특히 하나의 트랙에 두개의 데이터열을 기록하고 두 데이터열을 차동시켜 재생할 수 있는 기록 매체 및 재생 방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical disk recording medium and a reproduction method thereof, and more particularly, to a recording medium and a reproduction method capable of recording two data strings in one track and differentially playing the two data strings.

본 발명의 목적을 달성하기 위하여 본 발명은 복수의 트랙이 기록된 광 디스크는 하나의 트랙에 두 개의 데이터열이 기록된 것을 특징으로 하며, 본 발명의 다른 목적을 달성하기 위하여 본 발명은 하나의 트랙상에 기록되어 있는 두 개의 데이터열을 각각 읽어들이는 독출 단계, 독출 단계에서 출력된 각각의 2치 데이터열을 차동시켜 -1, 0, 1인 3치 데이터열로 출력하는 데이터열 출력 단계를 포함하는 것을 특징으로 한다.In order to achieve the object of the present invention, the present invention is characterized in that an optical disc in which a plurality of tracks are recorded is recorded with two data strings in one track. A reading step of reading two data strings recorded on a track, and a data string output step of differentially outputting each binary data string output in the reading step as a three-value data string of -1, 0, and 1; Characterized in that it comprises a.

본 발명에 의하면, 기존의 디스크와는 달리 하나의 트랙에 두 개의 데이터열을 기록하고 이들 신호를 차동신호로 만들어 데이터를 재생하기 때문에 기존에 비해 적어도 1.5배의 데이터 밀로 향상을 가질 수 있는 잇점이 있다.According to the present invention, unlike conventional disks, since two data strings are recorded on one track and these signals are made into differential signals to reproduce data, the data mill can be improved at least 1.5 times as compared to the conventional disk. have.
