Abstract: PROBLEM TO BE SOLVED: To provide an optical disk recording medium which makes data recording by having a recording film with guide grooves formed, wherein information such as rotation control information and address information is stably recorded and reproduced without performing information recording using wobble so as not to be erroneously recognized to be a pirated disk by a drive unit with a pirated version determination mechanism. SOLUTION: The guide grooves are formed without meandering, their widths are periodically modulated, and data encrypted by marks formed on a recording film along the guide grooves is recorded. Since information recorded by periodical width modulation of the guide grooves is detected by using a bandpass filter, the rotation control information and the address information are stably reproduced. Since the guide grooves are formed without meandering, encrypted and recorded contents are reproduced even in a drive unit with a pirated version determination mechanism like a ROM disk.
