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.
L'invention est une méthode d'enregistrement d'informations sur un support balayé par une sonde, ce balayage étant effectué sur la surface du support, lequel peut subir deux changements d'état ou plus par rapport à l'état de non-enregistrement. La sonde effectue l'enregistrement en balayant le support et en créant des alvéoles de façon intermittente sur celui-ci, chacune de ces alvéoles étant formée avec l'un des deux changements d'état ou plus selon l'information à enregistrer. Une méthode de reproduction d'informations ainsi enregistrées sur ce support est également divulguée, ainsi qu'un appareil utilisant cette méthode d'enregistrement et un appareil utilisant ladite méthode de lecture.
