摘要
PROBLEM TO BE SOLVED: To provide an optical information recording medium, a method and a system for holding information secrecy, with which the illegal use or the like of recorded information can be prevented. SOLUTION: When recording information on a CD-R 16, in addition to digital data 31, an automatic install program 32 and an operation control program 33 are written together. When the CD-R 16 is loaded into an information reproducing device, the automatic install program 32 is automatically started and the operation control program is made resident and started in the memory of the information reproducing device. When operation to digital data written on the CD-R 16 is detected, the operation control program 33 calls the entry of a password by interrupting this operation and when the inputted password is a regular password, interrupted operation is continued.
