Abstract
A recording head actuator assembly for correcting for tape mis-registration (TMR) in a tape drive. The assembly includes a recording head actuator including a recording head and actuators for laterally positioning the head relative to tracks of a tape. The assembly also includes a dynamic azimuth control (DAC) assembly that includes a flexural pivot and a rotation driver. The rotation driver applies a driving force on the flexural pivot causing the flexural pivot to rotate about a hinge axis and the head to rotate about a rotation axis passing through the head, from a first azimuth angle to a second azimuth angle. The rotation axis and the hinge axis coincide, and the rotation axis of the head is transverse to a direction of tape travel. In some useful implementations, the flexural pivot may include a planar outer flexure and a planar inner flexure arranged as a cross strip pivot.
