APPARATUS AND METHOD TO STORE INFORMATION IN A HOLOGRAPHIC DATA STORAGE MEDIUM

摘要

A method is disclosed to store information in a holographic data storage medium. The method supplies a holographic data storage medium and provides information. The method defines an Active storage portion for the holographic data storage medium and establishes a threshold access interval. The method determines if the information was last accessed within the threshold access interval. If the information was last accessed within said threshold access interval, the method then stores that information as one or more holograms encoded in said Active storage portion of the holographic data storage medium.
