ELECTRON RAY INFORMATION REPRODUCING METHOD AND ELECTRON RAY INFORMATION REPRODUCING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide an information reproducing method and an information reproducing medium which enable reduction of reading critical size of recording information which is a cause of hindrance of high density recording, and thus enable realization of the high density recording. SOLUTION: The electron ray information reproducing method is characterized in that information is read by using the difference of an amount of electric currents in the information recording medium obtained by irradiating the information recording medium with information recorded thereon by changing the quality of the information recording medium with electron rays, or the difference of an amount of electrons.
