1. A holographic recording system comprising;
at least one laser source configured to emit recording beams;
a first set of one or more stations configured to house a first set of waveguide cells;
a second set of one or more stations configured to house a second set of waveguide cells; and
a movable platform configured to move between a first position and a second position, wherein:
when the movable platform is in the first position, the at least one laser source is configured to emit a first set of one or more recording beams toward the first set of one or more stations; and
when the movable platform is in the second position, the at least one laser source is configured to emit a second set of one or more recording beams toward the second set of one or more stations.
