ABSTRACT:
This specification discloses a method of recording information on a recording medium which has the relative scanning of the recording medium by a probe for information recording, the relative scanning being effected along the surface of the recording medium, the recording medium being capable of forming two or more kinds of state changes relative to the state of non-recording, and a recording process onto the recording medium through the probe effecting the relative scanning, the recording process being carried out by intermittently forming bits on the recording medium, each of the bits being formed with one of the two or more kinds of state changes in conformity with recording information. The specification also discloses a method of reproducing information recorded on a recording medium by such information recording method. The specification further discloses an apparatus for carrying out the information recording method, and an apparatus for carrying out the information reproducing method.
