Abstract
This disclosure relates to a data storage medium, and in particular to a data storage medium comprising at least one high modulus layer used to control the overall degree of flatness in the storage medium.
Claims20
An asymmetric optical storage medium comprising a layer, which improves directional stability in said medium.
An asymmetric optical storage medium comprising the following layers:
- at least one substrate layer;
- at least one data layer which is in direct contact with said substrate layer;
- at least one high modulus layer which in direct contact with said data layer;
- and
- at least one thin film layer which is in direct contact with said high modulus layer.
A method for decreasing the tilt of an asymmetric optical storage medium, said method comprising an addition step wherein a high modulus layer is added to an optical storage medium so that the directional stability of said medium is increased.
