Abstract
A system and method for replicating optical data storage discs (e.g., holographic data storage discs) having multiple layers of data. Master discs providing for respective single layers of data are utilized, and each respective single layer of data from the master discs are replicate onto the optical data storage disc.
Claims36
A method of replicating optical data storage discs, comprising:
- providing master discs having a respective single layer of data;
- and
- optically replicating each respective single layer of data from the master discs into an optical data storage disc comprising multiple layers of data.
A method of replicating holographic storage discs, comprising:
- providing master discs each providing for a respective single layer of data to be replicated on a holographic data storage disc;
- and
- replicating each respective layer of data from the master discs into a holographic data storage disc.
A method of replicating optical data storage discs, comprising:
- disposing optical storage discs on a movable structure;
- disposing master discs at replication stations, wherein the master discs each having a single layer of data to be replicated on the optical storage discs;
- activating the structure to respectively position the optical storage discs adjacent each master disc;
- and
- optically replicating the single layers of data into the optical storage discs.
A system for replicating holographic data storage discs, comprising:
- replicating stations configured to hold stationary master discs having a respective layer of data to be replicated on a plurality of holographic data storage discs;
- and
- a structure configured to hold the plurality of holographic data storage discs and to pass the plurality of holographic data storage discs adjacent the replicating stations.
A method of replicating multiple layers of data into an optical storage disc, comprising replicating one layer of data at a time into the optical storage disc:
- via a plurality of master discs each providing for a different layer of data to be replicated;
- or via a single or plurality of master discs comprising at least one spatial light modulator (SLM), wherein states of pixels in the SLM are electrically changed to provide for replication of different layers of data;
- or both.
A system for replicating multiple layers of data into an optical storage disc, comprising:
- a master disc comprising a a spatial light modulator (SLM);
- a processor configured to change states of pixels in the SLM to respectivley provide for replication of each layer of data;
- a replicating station;
- and
- a structure configured to position the master disc and the optical storage disc adjacent one another at the replicating station.
