Optical information recording medium, reproduction apparatus, and reproduction method
The reliability of a super-resolution optical information recording medium whose capacity can be increased is increased. On an optical information recording medium (11) according to the present invention, a content is recorded as a pit group formed such that an average length Tm [nm] of a minimum mark length and a minimum space length becomes shorter than an optical system resolution limit, and reading speed information designating a reading speed in a range from 2×(4.92×Tm/149) [m/s] to less than (10000/60)×2×π×(24/1000) [m/s] is recorded as a reading speed for reproducing the content.
