In one embodiment, a data storage media comprises: a substrate comprising at least one plastic portion, an edge lift height of less than about 8&#x3bc;, and an axial displacement peak of less than about 500&#x3bc; under shock or vibration excitation; and at least one data layer on said substrate. The data layer can be at least partly read from, written to, or a combination thereof by at least one energy field, and, when the energy field contacts the storage media, the energy field is incident upon the data layer before it could be incident upon the substrate. In another embodiment, the data storage media comprises: a substrate comprising at least one plastic portion and an axial displacement peak of less than about 500&#x3bc; under shock or vibration excitation, and an areal density of about 10 Gbit/in; and at least one data layer on the substrate. The data layer can be at least partly read from, written to, or a combination thereof by at least one energy field, and, when the energy field contacts the storage media, the energy field is incident upon the data layer before it could be incident upon the substrate.

Data storage media utilizing a substrate including a plastic resin layer, and method thereof

The invention relates to transparent blends of polymers suitable for use in optical articles; the polymers contain residues of BCC and its derivatives, and have properties particularly suited for use in high density optical data storage media. The polymers further contain residues of other polymers, such as &#x3b1;-methyl polystyrene and polystyrene derivatives; bisphenols, such as bisphenol A; cycloaliphatic polyester resins, such as PCCD and its derivatives or some combination of each.

Data storage media containing transparent polycarbonate blends

The invention features a bulk light diffuser material. The bulk light diffuser material may be a sheet or film comprising about 95 to about 99.8 percent by weight of polycarbonate and about 0.2 to about 2.5 percent by weight of a particulate light diffusing component, based on the total weight of the polycarbonate and the light diffusing particles. The sheet material has a percent transmittance of at least 70% and a haze of at least 10% measured according to the American Society for Testing and Materials (ASTM) standard D 1003.

Bulk diffuser for flat panel display

The invention relates to transparent blends of polymers suitable for use in optical articles; the polymers contain residues of BCC and its derivatives, and have properties particularly suited for use in high density optical data storage media.
