摘要

A super resolution medium (1) is provided with an information signal region (11) whereupon contents of video, audio or the like are recorded; and a test read region (12) whereupon reproduction setting value adjusting information for adjusting setting values is recorded. The shortest mark length of a first prepit row formed in an information signal region (11) is shorter than the length of an optical system resolution limit of a reproducing device. The types of the mark lengths recorded in the test read region (12) in a second prepit row for adjusting the setting value are partially or entirely the same as the types of the mark lengths in the first prepit row. The second prepit row includes a prepit having a mark length shorter than the length of the optical system resolution limit of the reproducing device. Furthermore, the mark lengths in the first and the second prepit columns are of three types or more. In the super resolution medium (1), optimum reproduction can be performed for each medium.
