Abstract:
1. A data storage media, comprising: a substrate having a first side comprising a plastic portion, a surface roughness of less than about 10 Å, and an axial displacement peak of less than about 500μ under shock and/or vibration excitation when excited by a 1 G sinusoidal loading, wherein said plastic portion has a thickness of less than about 50μ; an additional layer having a thickness of less than about 1,000 Å. wherein said additional layer is disposed in physical contact with said plastic portion; and magnetic data layer on said additional layer, wherein said magnetic data layer has a coercivity of greater than about 1,500 ocrsted; wherein said data layer can be at least partly read from, written to, or a combination thereof by an energy field; and wherein, when the energy field contacts said data storage media the energy field is incident upon said data layer before it could be incident upon said substrate.
