Abstract:
1. An apparatus for reading or writing information on a media, the apparatus comprising: a body having a center of mass, a surface, and an electromagnetic transducer; an actuator disposed adjacent to said surface, said actuator including a first piece, a plurality of deformable elements coupled to said first piece, and a second piece coupled to said deformable elements, each of said deformable elements having a shape that changes in response to a signal to rotate said second piece relative to said first piece about an axis of rotation; wherein a distance between one of said deformable elements and said axis of rotation is less than a length of said deformable element, a distance between said transducer and said axis of rotation is at least several times greater than said distance between said deformable element and said axis of rotation; wherein one of said deformable elements is elongated in a first direction between said first piece and said second piece, said one deformable element having a thickness measured in a second direction that is perpendicular to said first direction, wherein said thickness is reduced adjacent to said center of rotation to form a relatively flexible region of said one deformable element adjacent to said axis of rotation.
