Abstract

1. 청구범위에 기재된 발명이 속한 기술분야1. TECHNICAL FIELD OF THE INVENTION

디스크상에 데이터를 기록하거나 기록되어 있는 데이터를 재생하는 미니 디스크 시스템에 관한 것이다.A mini disc system for recording data on a disc or reproducing the recorded data.

2. 발명이 해결하고자 하는 기술적 과제2. Technical problem to be solved by the invention

디스크에 기록된 데이터를 사용자의 실수나 타인으로부터 보호할 수 있는 보안방법을 제공한다.It provides a security method to protect the data recorded on the disk from user's mistake or others.

3. 발명의 해결방법의 요지3. Summary of Solution to Invention

맨 처음에 사용자가 부여한 비밀번호를 디스크의 사용자 목록표영역에서 사용하지 않고 비어있는 영역에 기록해 놓은 후, 이후에 기록, 재생, 소거명령시 비밀번호를 문의하여 일치할 경우에만 해당 명령을 수행한다.The password given by the user is first recorded in an empty area instead of being used in the user list table area of the disk. Then, the command is executed only if the password is matched after a record, playback, or erase command.

4. 발명의 중요한 용도4. Important uses of the invention

미니 디스크 시스템에서 디스크에 기록된 데이터를 보호하는데 이용한다.It is used to protect the data recorded on the disk in the mini disk system.
