Abstract
A holographic data storage medium is provided, which includes a first substrate; a second substrate which has a dimension larger than that of the first substrate; and a holographic-recording layer which is provided between the first substrate and the second substrate; wherein the second substrate has a support portion which is disposed outside the first substrate and which is supported by the recording/reading apparatus. The holographic data storage medium makes it possible to realize the miniaturization and the optimization of the structure of the holographic data storage medium having an outer edge portion to be held in a recording/reading apparatus and to record and reconstruct information more correctly.
