Abstract
A data storage device can employ a gimbal tongue flexure suspended from a load beam with a transducing head mounted to the gimbal tongue flexure. The transducing head can be separated from a magnetic recording medium by an air bearing. At least one active or non-active damper may be positioned on a strut of the gimbal tongue flexure.
Claims20
An apparatus comprising:
- a gimbal tongue flexure suspended from a load beam;
- a transducing head mounted to the gimbal tongue flexure, the transducing head separated from a magnetic recording medium by an air bearing;
- and
- a first active damper positioned on a first strut of the gimbal tongue flexure, the first active damper comprising a damping layer physically contacting the first strut, the damping layer separating an electrode from the first strut.

An apparatus comprising:
- a gimbal tongue flexure suspended from a load beam;
- a transducing head mounted to the gimbal tongue flexure, the transducing head separated from a magnetic recording medium by an air bearing;
- a first non-active damper positioned on a strut of the gimbal tongue flexure;
- and
- a second non-active damper positioned on the first strut, separated from the first non-active damper.
2 more elements
A method comprising:
- arranging a first active damper on a first strut of a gimbal tongue flexure suspended from a load beam, the gimbal tongue flexure supporting a transducing head an air bearing distance from a magnetic recording medium;
- encountering at least one frequency with the first active damper;
- converting the at least one frequency to an electrical signal with the first active damper;
- altering the electrical signal with a damping component connected to the first active damper;
- and
- inducing mechanical motion of the first active damper with the altered electrical signal, the mechanical motion altering physical motion of the gimbal tongue flexure.
