The reliability of a super-resolution optical information recording medium whose capacity can be increased is increased. On an optical information recording medium () 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&#xd7;(4.92&#xd7;Tm/149) [m/s] to less than (10000/60)&#xd7;2&#xd7;&#x3c0;&#xd7;(24/1000) [m/s] is recorded as a reading speed for reproducing the content.

Optical information recording medium, reproduction apparatus, and reproduction method

An optical information recording medium has a first information recording layer () and a second information recording layer () each of which includes (i) a group of pre-pits () constituting marks () and spaces () and (ii) a super-resolution film (), the marks () and the spaces () having different lengths, an average length of a smallest mark that is smallest in length and a smallest space that is smallest in length being less than or equal to a resolution limit of a reproduction optical system for reproducing information recorded on the first information recording layer () and the second information recording layer (), the group of pre-pits () being formed so that a push-pull signal for the reproduction optical system to reproduce the information recorded by the group of pre-pits is negative in polarity. This provides an inexpensive and high-capacity multilayer optical information recording medium based on a super-resolution technology.
