Abstract: A holographic data storage system is disclosed. The data storage system includes a holographic data storage media adapted to receive a data beam and a reference beam and store a data pattern associated with the data beam. The stored data pattern is expressed by a holographic representation corresponding to data elements of the data beam.

Abstract: A method of storing information in a protein-based medium having long-lived nonvolatile or near-nonvolatile states is disclosed. The method includes preexposing a bacteriorhodopsin medium to a preexposure pump beam for a predetermined length of time, providing a reference beam and a data beam from a coherent light source, the data beam being modulated to transmit data, and concurrently exposing the bacteriorhodopsin medium to the reference beam and the data beam for a length of time sufficient to form a holographic representation of the data in the medium and subsequently read the hologram. Also included is a method exposing the medium to essentially fully utilize the available index change and share the available index change between N multiplexed holograms in a holographic data storage system.

Abstract: A holographic memory device for use in a personal electronic device is disclosed. The device contains a holographic data storage media adapted to store a data pattern associated with a data beam. The device has capability for reading and writing to the holographic data storage media. The device contains a personal electronics device interface for receiving data from and providing data to a host personal electronics device. The device reads and writes data to the holographic data storage media in response to requests received via the personal electronics device interface.
