Reading system for use with optical disc memory system utilizing a smectic chiral liquid crystal |
摘要 |
An improved magneto-optical disc memory with a ferroelectric liquid crystal (FLC) is shown. As FLC a chiral smectic liquid crystal is employed to exhibit a bistability between a pair of substrates which have easy polarization axes normal to each other. Information to be recorded is written on the disc in terms of a binary system by use of the bistability. Reproduction is performed using a polarizing plate and a photodetector.
