Abstract
A head suspension for mounting and supporting the head assembly in a disc drive. The head suspension includes a ramp contact feature located adjacent the leading edge of the head assembly, and the ramp contact feature is in the form of an inclined cylinder with a spherical contact end. The shape of the ramp contact feature allows for simplification of the ramp surface profile and provides the ability to allow for assembly tolerance build-up in multi-disc disc drive assemblies.
