Abstract
Exposing a uniformly aligned discotic columnar liquid crystal to an ar gon ion laser beam results in a reorientation, thereby changing the op tical properties of the liquid crystal. We have studied this new optic al storage effect for a polymer dispersed metallomesogenic compound wh ich exhibits a columnar phase at room temperature. The writing energy is approximate to 3.5 J cm(-2). The stored information can be erased b y heating and subsequent shearing of the sample.
