Abstract
An optical pickup assembly includes a first optical pickup unit (OPU) and a second OPU. The OPUs are either stacked on each other in separate housings or integrated together in a common housing such that the OPUs are arranged laterally across a tape path and are positioned at a longitudinal position along the tape path.
Claims20
An optical pickup assembly comprising:
- a first optical pickup unit having an objective lens;
- and
- a second optical pickup unit having an objective lens;
- wherein the optical pickup units are arranged laterally above one another across a tape path extending in a longitudinal direction and are both positioned at the same longitudinal position along the tape path with the objective lens of one of the optical pickup units being laterally higher across the tape path than the objective lens of the other one of the optical pickup units at the same longitudinal position of the optical pickup units.
(canceled)
An optical tape data storage machine for reaching and writing to an optical tape configured to move along a tape path extending in a longitudinal direction, the machine comprising:
- a plurality of optical pickup assemblies, each optical pickup assembly including first and second optical pickup units, each optical pickup unit having an objective lens;
- wherein the optical pickup units of each optical pickup assembly are arranged laterally above one another across the tape path;
- wherein the optical pickup assemblies are positioned at respective longitudinal positions along the tape path such that the optical pickup units of each optical pickup assembly are arranged laterally above one another across the tape path and are both positioned at the same respective longitudinal position of the optical pickup assembly along the tape path with the objective lens of one of the optical pickup units of the optical pickup assembly being laterally higher across the tape path than the objective lens of the other one of the optical pickup units of the optical pickup assembly at the same respective longitudinal position of the optical pickup assembly along the tape path.
An optical tape data storage system comprising:
- an optical tape configured to move along a tape path, the optical tape having a tape width;
- and
- an optical pickup assembly including a first optical pickup unit and a second optical pickup unit, wherein each optical pickup unit has an objective lens;
- wherein the optical pickup units are arranged laterally above one another across the tape width and are both positioned at a at the same longitudinal position along the tape path with the objective lens of one of the optical pickup units being laterally higher across the tape width than the objective lens of the other one of the optical pickup units at the same longitudinal position of the optical pickup units.
