Abstract: The use of poly(parabanic acids) as a substrate for magnetooptic data storage applications. For example, the substrate is characterized by having optical inactivity and may be made free of stress induced dichroism and birefringence, thus being particularly suitable for use with magneto-optic storage films where information stored is read by utilizing the Kerr or Faraday effects.
