Abstract

본 발명은 광디스크내에 데이터보안유지 플래그와 비밀번호를 설정해 놓고서 광디스크의 데이터를 비밀번호를 알고 있는 특정인만이 억세스할 수 있도록 함으로써 보안유지가 가능한 광디스크장치를 제공하기 위한 것이다.The present invention is to provide an optical disk apparatus capable of maintaining security by setting a data security holding flag and a password in an optical disk so that only a specific person who knows the password can access the data on the optical disk.

이를 위해 본 발명은, 소정의 기록데이터를 기록 및 재생하는 데이터영역을 갖춘 기록매체를 기록 및 재생하는 광디스크장치에 있어서; 기록모드가 데이터보안유지용이면 상기 데이터영역의 제1소정 부분에 데이터보안 유지 플래그를 설정하고서 비밀번호를 입력받아 상기 데이터영역의 제2소정 부분에 그 비밀번호를 저장하고, 그 후 시작 어드레스를 알려주는 시작 포인터나 연결포인터의 값에다 소정치를 가산 또는 감산한 포인터에 데이터를 기록하도록 되어 있는 것을 특징으로 한다.To this end, the present invention is directed to an optical disc apparatus for recording and reproducing a recording medium having a data area for recording and reproducing predetermined record data; If the recording mode is for data security maintenance, the data security maintenance flag is set in the first predetermined portion of the data area, the password is input, the password is stored in the second predetermined portion of the data area, and then the start address is informed. It is characterized in that data is recorded in a pointer obtained by adding or subtracting a predetermined value to a value of a start pointer or a connection pointer.
