  • Systems and methods for data storage and retrieval
    Patent number: 10656287
    Abstract: A method includes directing a probe beam to a target that includes an array of data portions in a data storage medium arranged so that a beam area of the probe beam extends across a plurality of adjacent data portions, the array including a data portion subset with each data portion of the subset responsive to the probe beam to produce a response illumination, receiving the response illumination at a detector, and determining data values corresponding to the plurality of adjacent data portions based on the received response illumination. Apparatus and systems are also disclosed.
    Type: Grant
    Filed: April 3, 2019
    Date of Patent: May 19, 2020
    Assignee: Battelle Memorial Institute
    Inventors: David W. Gotthold, Andrew J. Stevens, Nigel D. Browning, Eric Jensen, Nathan L. Canfield, Alan G. Joly

  • APPARATUS AND METHOD OF MULTI-BIT AND GRAY-SCALE HIGH DENSITY DATA STORAGE
    Publication number: 20150302884
    Abstract: A data storage apparatus and method of storing data are disclosed. An array of irradiation sources are provided for writing on an optically stimulated luminescence (OSL) material. The OSL material includes data storage pixels or spots. Each pixel or spot includes gray-scale levels with higher order bits and variable intensity. A light source stimulates luminescence on the OSL material.
