ABSTRACT:
To greatly increase the storage density of a storage apparatus, an electron beam E emitted from a cold cathode101is accelerated by an accelerating electrode102, caused to converge by a convergence electrode103, deflected by a deflection electrode104and applied to a minute region of a storage film105. The storage film105includes, for example, a phase change film105a. The film is rapidly heated and cooled to change into an amorphous state upon irradiation with an electron beam E with high energy, while being gradually cooled to change into a crystallized state upon irradiation with an electron beam E with approximately intermediate energy, thereby storing data. Upon irradiation with an electron beam E with low energy, the potential difference between a detection electrode105band an anode105cis detected depending on the state, i.e., the amorphous or crystallized state, thereby reading stored data.
