Abstract
There is provided volume holographic data recording media having a recording layer which is capable of recording interference fringes generated by interference of light having excellent coherence as fringes having different refractive indexes and undergoes holographic data recording by an amount of spatial shift distance of not more than 3 μm which is smaller than that of conventional media.

Volume holographic data recording media having a recording layer being capable of recording interference fringes generated by interference of light having excellent coherence as fringes having different refractive indexes,
- wherein an amount of spatial shift distance of holograms recorded on the recording layer is from 0.1 μm to 3 μm,
- at least two holograms with a spatial shift of less than 3 μm are recorded in the medium, and
- a composition used for the recording layer comprises a fluorine-containing polymer.
Volume holographic data recording media having a reflecting layer and a recording layer on a substrate, wherein a servo pit pattern is formed on the reflecting layer, a pit length is less than 2 μm, an amount of spatial shift distance of holograms recorded on the recording layer is from 0.1 μm to 3 μm, and a composition used for the recording layer comprises a fluorine-containing polymer.
