ABSTRACT:
A magneto-optical recording medium containing a substrate formed from polymers which are prepared by polymerization without ring cleavage, of monomers comprising polycyclic olefins, such as norbornene, results in a recording medium having increased thermal dimensional stability and resistance to hydrolysis, and decreased moisture absorption and birefringence.
