Abstract
A holographic storage medium, a method of manufacturing the holographic storage medium and a holographic storage device incorporating the storage medium. In one embodiment, the holographic storage medium includes: (1) first and second spaced-apart substrates, the first substrate being plastic and (2) a photopolymer core located between said first and second substrates and having a coefficient of thermal expansion such that said first and second substrates and said photopolymer core cooperate to respond substantially isotropically to a change in temperature.

A holographic storage medium, comprising:
- first and second spaced-apart substrates, said first substrate being plastic;
- and
- a photopolymer core located between said first and second substrates such that said holographic storage medium is optically flat and having a coefficient of thermal expansion such that said first and second substrates and said photopolymer core cooperate to respond substantially isotropically to a change in temperature.
A method of manufacturing a holographic storage medium, comprising:
- forming a first plastic substrate;
- forming a second substrate;
- forming a photopolymer core between said first and second substrates such that said holographic storage medium is optically flat, said photopolymer core having a coefficient of thermal expansion such that said first substrate and said photopolymer core cooperate to respond substantially isotropically to a change in temperature.
