Abstract
An assembly according to one embodiment includes a first module and a second module each having multiple transducers, wherein the first module is movable relative to the second module; a tape dimensional stability compensation mechanism for tilting the modules to control a transducer pitch presented to a tape; and an actuator adapted to exert a force on both modules for causing the relative movement of the first module with respect to the second module for aligning the transducers of the first module with the transducers of the second module in a direction of tape travel thereacross.
Claims20
An assembly comprising:
- a first module and a second module each having multiple transducers, wherein the first module is movable relative to the second module;
- a tape dimensional stability compensation mechanism for tilting the modules to control a transducer pitch presented to a tape;
- and
- an actuator adapted to exert a force on both modules for causing the relative movement of the first module with respect to the second module for aligning the transducers of the first module with the transducers of the second module in a direction of tape travel thereacross.
A system, comprising:
- opposing modules generally aligned with each other in a direction of tape travel thereacross, positions of the two modules being fixed relative to each other in every direction of movement except one, each module having multiple transducers arranged in an array;
- and
- an actuator adapted to exert a force on both modules for causing a relative movement of the modules in the one direction of movement.
A method, comprising:
- determining a desired pitch for transducers for reading and/or writing to a magnetic tape;
- tilting a head to achieve the desired pitch, the head having opposing modules generally aligned with each other in a direction of tape travel thereacross, positions of the two modules being fixed relative to each other in every direction of movement except one, each module having an array of the transducers;
- and
- changing a state of an actuator for causing a relative movement of the modules in the one direction of movement for aligning the transducers of the modules in the direction of tape travel thereacross.
