Abstract

A device is provided which is capable of high storage density with rapid reading capability. Information is written with a high energy electronbeam gun onto a resist that is coated on a piezoelectric substrate. After development, the information is read off the resist with another electron-beam gun. The piezoelectric material is used to detect when the electron beam is incident upon the developed-out areas of the resist and hence reproduces the written information.
