  • Patent number: 4996667
    Abstract: A novel electron beam addressible recording device is disclosed, in which a recording layer formed of ferroelectric material having secondary electron emissivity .delta. greater than 1 is provided in a vacuum chamber. One surface of the recording layer is applied with a predetermined potential and the other surface is caused to have different potentials from the predetermined potential by scanning it with an electron beam. The difference of the potentials between two surfaces of the recording layer, causes poling patterns corresponding to the data recorded to be formed. The recorded data in the form of poling direction can be detected by electron beam scanning.
