Abstract
Holographic storage hardware enabled locking includes directing a first reference beam associated with a first process at a storage location in a holographic data storage medium, and detecting, with a detector while the first reference beam is directed at the storage location, whether a second reference beam associated with a second process is also directed at the storage location. Based on the detecting, a signal is generated indicating whether the storage location is locked.
Claims25
A method for holographic storage hardware enabled locking, comprising:
- directing a first reference beam associated with a first process at a storage location in a holographic data storage medium, wherein the first reference beam is generated with a first laser light source;
- detecting, with a detector while the first reference beam is directed at the storage location, whether a second reference beam associated with a second process is also directed at the storage location, wherein the second reference beam is generated with a second laser light source;
- and
- generating, based on the detecting, a signal indicating whether the storage location is locked.
An apparatus for holographic storage hardware enabled locking, comprising:
- a first laser light source to generate a first reference beam associated with a first process;
- a mirror to direct the first reference beam at a storage location in a holographic data storage medium;
- and
- a detector to detect, while the first reference beam is directed at the storage location, whether a second reference beam associated with a second process is also directed at the storage location, and generate, based on detection of the detector, a signal indicating whether the storage location is locked,
- wherein the second reference beam is generated with a second laser light source.
A system for holographic storage hardware enabled locking, comprising:
- a storage controller to handle read requests and write requests directed to a holographic data storage medium;
- a gating light source to facilitate writing of data to the holographic data storage medium;
- a first laser light source to generate a first reference beam associated with a first process;
- a mirror to direct the first reference beam at a storage location in the holographic data storage medium;
- and
- a detector to detect, while the first reference beam is directed at the storage location, whether a second reference beam associated with a second process is also directed at the storage location, and output to the storage controller, based on detection of the detector, a signal indicating whether the storage location is locked,
- wherein the second reference beam is generated with a second laser light source.
A method for holographic storage hardware enabled locking, comprising:
- generating a plurality of reference beams, including a first reference beam associated with a first process and a second reference beam associated with a second process,

- directing the first reference beam at a storage location in a holographic data storage medium;
- detecting, with a detector while the first reference beam is directed at the storage location, whether the second reference beam is causing interference with the first reference beam;
- and
- generating, based on the detecting, a signal indicating whether the storage location is locked.
