Application 08/327,389
to a ramp assembling method and apparatus for loading and
unloading an actuator arm in a disc drive. On page 3 of the
specification, Appellant discloses that Figure 1 is a cutaway top
view plan of one embodiment of Appellant’s invention. Appellant
discloses on page 5 of the specification that the surfaces of
extension 217 and ramp assembly 230 contacting each other are
coated with a hard, low-friction fluoropolymer loaded with
Teflon. Appellant discloses that tests were conducted with these
compounds showing excellent results in the form of low friction
and low wear. Appellant discloses on page 6 that because a small
amount of wear (debris) and external contamination are always
present between two rubbing surfaces (flexure (217) and, ramp
(272) and level (272) surfaces of the ramp assembly), a very
light lubricant is applied to the stationary surface. Appellant
discloses that flying debris are minimized with a lubricant which
combines the debris within the lubricant.
Representative claims 1 and 12 are reproduced as
follows:
1. A disc drive system comprising:
