  • Photorefractive, erasable, compact laser disk
    Patent number: 5003528
    Abstract: The invention comprises a data storage device in which ferroelectric photorefractive cells 12 susceptible to polarization for the storage of digital information are positioned on a carrier medium, preferably a disk 10, which supports the cells and allows access to them by optical beams 14, 16 and electric fields 21. A non-contacting data writing means comprising dual electrodes 20, 22 is used to change the polarity of the cells. A non-contacting data reading means comprising lasers 14, 16 and detectors 30, 34 is used to observe photorefractive effects so that the polarity of such cells 12 can be determined. The polarity of the ferroelectric photorefractive cells is coded for the storage of digital information.
