Abstract
A method and apparatus for storing data is provided. One implementation involves providing a fiber medium for storing data, wherein the fiber medium has a characteristic configured to irreversibly change when exposed to write irradiation. The fiber medium is logically partitioned into cells along the length of the fiber medium. Data is stored in a cell of the fiber medium by exposing the cell to write irradiation to irreversibly change characteristic of the bulk of the cell.
