Abstract
An actuator assembly is provided having a ramp for unloading a transducing head from a storage medium. The actuator assembly includes an actuator arm rotatable about a pivot point and configured to access data on a storage medium. The actuator arm has a base end coupled to a lift tab and a distal end coupled to a transducing head. The actuator assembly also includes an inclined surface located adjacent the base end. The inclined surface is configured to engage with the lift tab to guide the transducing head away from the storage medium.
Claims16
An actuator assembly comprising:
- an actuator arm rotatable about a pivot point and configured to access data on a storage medium, the actuator arm having a base end coupled to a lift tab and a distal end coupled to a transducing head;
- a crash stop located adjacent the base end of the actuator arm, the crash stop comprising a first side end having a first inner-facing surface that prevents the transducing head from traveling beyond an outer diameter of a storage medium, a second side end having a second inner facing surface and a top end having a bottom facing surface that couples the first side end to the second side end, the first inner facing surface of the first side end and the second inner facing surface of the second side end being substantially perpendicular to the bottom facing surface of the top end;
- and
- a ramp having an inclined surface and an opposing top surface that is parallel with the bottom facing surface of the top end of the crash stop, the ramp being directly coupled to and protruding from the second inner facing surface of the second side end of the crash stop to a point between the first side end and the second side end of the crash stop, wherein upon rotation of the actuator arm about the pivot point to the inner diameter of the storage medium the lift tab slides along the inclined surface to tilt the actuator arm about a hinge for guiding the transducing head away from the storage medium.

A data storage system comprising:
- an actuator arm rotatable about a pivot point and configured to access data on the storage medium, the actuator arm having a base end coupled to a lift tab and a distal end coupled to a transducing head;
- a crash stop located adjacent the base end of the actuator arm, the crash stop comprising a first side end that prevents the transducing head from traveling beyond an outer diameter of a storage medium, a second side end and a top end that couples the first side end to the second side end, the first side end and second side end being substantially perpendicular to the top end;
- and
- a ramp located adjacent the base end and directly coupled to an inner facing surface of the second side end of the crash stop and protruding from the inner facing surface to a point between the first side end and the second side end of the crash stop, the ramp having a fixed inclined surface that is configured to engage with the lift tab to guide the distal end of the actuator arm towards a top cover of the data storage system.

- and
- a ramp located adjacent the base end and directly coupled to an inner facing surface of the second side end of the crash stop and protruding from the inner facing surface to a point between the first side end and the second side end of the crash stop, the ramp having an inclined surface and an opposing top surface spaced apart from and facing the bottom facing surface of the top end of the crash stop, wherein the inclined surface is configured to engage with the lift tab to guide the transducing head into an unloaded position and disengage with the lift tab to guide the actuator arm into a loaded position.
