ABSTRACT:
An improved magneto-optical disc memory writing and reading method with a ferroelectric liquid crystal (FLC) is shown. As FLC a chiral smectic liquid crystal is employed to exhibit a hysteresis between a pair of substrates which have easy polarization axes normal to each other. Informations to be recorded are written on the disc in terms of a binary system by use of the hysteresis.
