A method for reproducing an optical information recording medium,
- the optical information recording medium comprising:
- a first area in which a content is to be recorded by forming recording marks, one or more of the recording marks being shorter than a length of a resolution limit of an optical system in a reproducing device;
- and
- a second area in which medium identification information for specifying a type of the medium and information regarding reproduction speed for reproduction of the content in the first area of the optical information recording medium are recorded by use of concave portions and/or protrusions that are not shorter than the resolution limit of the optical system,
- the method comprising the step of controlling reproduction speed based on the information regarding reproduction speed.
