Abstract
An optical data-recording system comprises a laser, a dynamic digital hologram, an electronic controller, and a scanning mechanism. The dynamic digital hologram includes a plurality of holographic zones, and is configured to direct the irradiance received thereon to an optical recording medium. The electronic controller is operatively coupled to the dynamic digital hologram and configured to control the irradiance directed from each of the holographic zones. The scanning mechanism is configured to change a relative positioning of the laser versus the dynamic digital hologram so that each of the holographic zones is irradiated in sequence by the laser.
Claims20
An optical data-recording system comprising:
- a laser;
- a dynamic digital hologram including a plurality of independently programmed holographic zones, each configured to direct irradiance received thereon to an optical recording medium;
- an electronic controller operatively coupled to the dynamic digital hologram to control the irradiance directed through each of the independently programmed holographic zones;
- and
- a scanning mechanism configured to change a relative positioning of the laser versus the dynamic digital hologram, so that irradiance from the laser is directed in sequence over each of the independently programmed holographic zone.
A method to record data on an optical recording medium, the method comprising:
- addressing a plurality of holographic zones of a dynamic digital hologram so as to independently program each holographic zone and thereby control an irradiance to be directed from each holographic zone when irradiated;
- irradiating a first of the independently programmed holographic zones of the dynamic digital hologram with a laser, via a scanning mechanism;
- and
- advancing the scanning mechanism to change a relative positioning of the laser versus the dynamic digital hologram, so that irradiance from the laser is directed in sequence to each of the independently programmed holographic zones.
An optical data-recording system comprising:
- a laser;
- one or more optically addressable spatial light modulators (OASLMs), each OASLM including a plurality of holographic zones, and being configured to direct irradiance received on each of the holographic zones to an optical recording medium;
- an image projector configured to project an image onto each of the holographic zones of the one or more OASLMs, so as to independently program each of the holographic zones and thereby control the irradiance directed from each of the holographic zones;
- and
- a scanning mechanism configured to change a relative positioning of the laser versus the one or more OASLMs, so that irradiance from the laser is directed in sequence to each of the independently programmed holographic zones.
