FABRICATION OF DIGITAL MEDIA USING ION BEAM TECHNOLOGY AND DIGITAL MEDIA CREATED USING ION BEAM TECHNOLOGY

摘要

A method for writing data to an optical medium includes directing intermittent pulses of beam of ions from an ion source onto an optical medium (S04) in a controlled pattern for creating surface features on the optical medium, the surface features representing data. A system (500) for performing this method, according to one embodiment, includes a medium receiving portion (502) for holding an optical medium (504), an ion source (506) for emitting a beam of ions (508) at the optical medium (504) on the medium receiving portion (502) and a steering mechanism (510) for directing the ion beam onto the optical medium (504) in a controlled manner. The beams of ions strikes the optical medium in intermittent pulses for creating surface features of the optical medium (504).
