摘要:
In a process and apparatus for manufacturing an optical storage device, a film (4) of liquid crystal (LC) material, such as an LC polymer, is deposited on an elongate substrate (1), and the substrate is fed through a temperature-controlled region (5) in which the temperature of the film is raised above the glass transition temperature of the LC material and is subsequently lowered so that the material is initialised to an optimum light-scattering texture. The substrate may then be cut into sections, each for use as an optical storage device.
