Recording device and reproducing device.

摘要

A device is provided for recording and/or reproducing information. It comprises a probe electrode (102), a recording medium (1) disposed opposite to the probe electrode (102) so that a tunnel current can flow when a voltage is applied therebetween and either one or both of (a) means (108,122) for applying a writing voltage between the probe electrode (102) and the medium (1) to record information thereon and (b) means (105,112) for applying a reading voltage between the probe electrode (102) and the medium (1) to detect information recorded thereon. The medium is an amorphous semiconductor, e.g a chalcogenide glass, an amorphous silicon film or a laminate of amorphous silicon films.
