Abstract
Official abstract text for this publication.
A method and an apparatus for data storage based on fibers are described. Data are stored as marks in a surface of a fiber or in a volume near the surface of the fiber. Data marks are written to or read from the fiber by irradiating the surface of the fiber with at least one radiation beam. The fiber has calibration marks for controlling a speed of the fiber relative to the at least one radiation beam.
First claim
Opening claim text (preview).
What is claimed, is: 1. An apparatus for writing data to a diamond-shaped polymer fiber, with two or more light sources for emitting two or more light beams for writing data to the diamond-shaped polymer fiber, wherein the apparatus writes marks into a surface of the diamond-shaped polymer fiber along two or more tracks parallel to an axis of the diamond-shaped polymer fiber by independently irradiating the surface of the diamond-shaped polymer fiber with the two of more light beam…
