Abstract
This disclosure relates to a data storage medium, and in particular to a data storage medium comprising at least one high modulus layer. In one embodiment, an asymmetric optical storage medium can comprise: a substrate layer comprising polyarylene ether, a high modulus layer comprising a thermoset, and a data layer disposed between the modulus layer and the substrate layer. The high modulus layer has a tensile modulus that is greater than a substrate layer tensile modulus. In another embodiment, an asymmetric optical storage medium can comprise: a substrate layer comprising polyarylene ether and having surface features and a high modulus layer disposed on the side of the substrate comprising the surface features. The surface features can comprise pits. The high modulus layer can comprise a thermoset, and can have a tensile modulus that is greater than a substrate layer tensile modulus.
