Abstract
The invention includes a method of A wipping part of the load ramp is a convex finger crossing the read-write head path of motion with respect to a lifting tab engagably moving across the loading ramp.
Claims14
A loading ramp for a read-write head coupled to a lifting tab by a head suspension assembly, comprising:
- a lifting tab path for engaging said lifting tab to create a motion path for said read-write head based upon said lifting tab engagably moving along said lifting tab path;
- a convex finger contacting said motion path of said read-write head to provide a wiping of said read-write head;
- wherein said motion path for said read-write head includes a parking region;
- and
- wherein said convex finger contacting said motion path outside said parking region;
- wherein said head suspension assembly is contained in an actuator accessing at least one disk media surface;
- and
- wherein said loading ramp is located outside said disk media surface;
- wherein said read-write head is at least partially covered with a lubricant drop providing a lubricant drop surface;
- wherein said convex finger contacting said motion path of said read-write head is further comprised of:
- said motion path of said read-write head approaching within a distance of said convex finger breaks said lubricant drop surface to provide said wiping of said read-write head.

A method of wiping a read-write head mechanically coupled to a lifting tab on a head suspension assembly on a loading ramp in a disk drive, comprising the steps of:
- loading said read-write head into a parking region based upon said lifting tab engaging said loading ramp;
- wiping said read-write head on a wiping part of said loading ramp when said lifting tab engages said loading ramp and when said read-write head is outside in said parking region;
- and
- wherein said wiping part is a convex finger crossing said read-write head path of motion with respect to said lifting tab engagably moving across said loading ramp;
- wherein said read-write head is at least partially covered with a lubricant drop providing a lubricant drop surface;
- wherein said convex finger contacting said motion path of said read-write head is further comprised of:
- said motion path of said read-write head approaching within a distance of said convex finger breaks said lubricant drop surface to provide said wiping of said read-write head;
- and
- wherein said disk drive contains said head suspension assembly and said loading ramp.
