OPTICAL RECORDING MEDIUM FOR PERFORMING SUPER RESOLUTION REPRODUCTION AND OPTICAL RECORDING AND REPRODUCTION METHOD THEREOF

摘要

The invention performs super resolution reproduction with a recording layer and a signal reproducing functional layer laminated on a grooved substrate. A length of a mark recorded in a Mark Position method is only one length that is less than the resolution limit in an optical system to be used, and recording marks are formed both on a land and in a groove of the grooved substrate.
