Abstract :
Consideration is given to the 1991 state of the art in materials used for polymeric substrates for magnetooptic (MO) media. The focus of this work is primarily on polycarbonate and the most significant substrate property confronting the field, namely, birefringence. Other constraints placed by optical storage technology on the substrate material are discussed along with new materials and research activities aimed at circumventing some of the limitations
