摘要

A disk authentication method, system, program, and a computer readable recording medium containing the program are disclosed. A main controller of a host computer executes a data acquisition step for acquiring, from an optical disk, unique data that is recorded on an information track on the optical disk in accordance with a predetermined rule and an authentication step for authenticating the optical disk based on the unique data acquired in the data acquisition step. The disk authentication method thus prevents data illegally copied onto the optical disk from being used.
