Abstract
An electromagnetically controlled drive system for accessing a data storage medium comprises an optical signal generator and a reflector element adapted to receive an optical signal from the optical signal generator. The reflector element is also adapted to direct the optical signal toward the data storage medium. The system also comprises an electromagnetic element adapted to generate an electromagnetic field proximate to the reflector element. The reflector element is adapted to respond to the electromagnetic field to move the optical signal relative to the data storage medium in response to a change in the electromagnetic field.
Claims20
An electromagnetically controlled drive system for accessing a data storage medium, comprising:
- an optical signal generator;
- a reflector element adapted to receive an optical signal from the optical signal generator and direct the optical signal toward the data storage medium;
- and
- an electromagnetic element adapted to generate an electromagnetic field proximate to the reflector element, the reflector element adapted to respond to the electromagnetic field to move the optical signal relative to the data storage medium in response to a change in the electromagnetic field, wherein the electromagnetic element comprises at least a multi-layer printed circuit board with conductive traces formed on at least one layer of the printed circuit board.
A method for accessing a data storage medium, comprising:
- directing an optical signal toward the data storage medium via a reflector element;
- and
- generating an electromagnetic field proximate to the reflector element, the reflector element adapted to respond to the electromagnetic field to move the optical signal relative to the data storage medium in response to a change in the electromagnetic field, wherein generating the electromagnetic field comprises selectively generating a current through at least one of a plurality of conductive traces formed on a printed circuit board.
An electromagnetically-controlled drive system for accessing a data storage medium, comprising:
- an optical signal generator;
- a reflector element disposed in movable relation relative to the data storage medium and the optical signal generator, the reflector element adapted to receive an optical signal from the optical signal generator and direct the optical signal toward the data storage medium;
- and
- an electromagnetic element configured to generate an electromagnetic field proximate to the reflector element, the reflector element adapted to move relative to the data storage medium and the optical signal generator in response to a change in the electromagnetic field, wherein the electromagnetic element comprises a plurality of conductive traces formed on a printed circuit board configured to generate the electromagnetic field.
