Abstract
A system for unloading heads from and loading heads into cooperative engagement with discs in a disc drive, including a novel head suspension for mounting and supporting the heads. The head suspension includes a primary ramp contact feature formed as a portion of the load beam portion of the head suspension and a secondary ramp contact feature formed as an extension of the mounting tab of the gimbal portion of the head suspension. The primary ramp contact feature acts as the principal lifting mechanism of the head suspension, while the secondary ramp contact feature serves to controllably lift the head. In an alternative embodiment, only the secondary ramp contact feature is used for the unloading and loading of the head.
