An optical erasable liquid crystal disc memory system is provided which includes a rotating liquid crystal information storage medium confined by two surfaces. Various thin films on the surfaces are used to establish the proper conditions within the liquid crystal medium which, in combination with incident radition and applied voltages, accomplish the read, write, and erase functions. The resulting system provides a locally erasable optical disc memory with high density storage, long-term information stability under a wide range of temperature, and read, write, and erase times compatible with modern high speed computers.
