Abstract
A super resolution medium () is provided with an information signal region () where a content, such as a video or audio content, is recorded and a test read region () where reproduction setting value adjustment information is recorded for adjusting a setting value for reproduction. A shortest mark length on a first prepit row formed in the information signal region () is shorter than a length of an optical system resolution limit of a playback apparatus. The types of mark lengths, recorded in the test read region (), on the second prepit row for adjusting the setting value are the same as part or all types of mark lengths on the first prepit row. Further, the second prepit row includes a prepit having a mark length shorter than the length of the optical system resolution limit of the payback apparatus. Still further, each of the first and second prepit rows has at least three types of mark lengths. With this arrangement, optimum reproduction can be performed for each medium in the super resolution medium ().
