Abstract
A disc drive unit includes an actuator assembly with a suspension assembly supporting a head and a ramp positioned to guide the head toward or away from a data storage surface. The head facilitates data transmission with respect to the data storage surface. The actuator assembly positions the head at selected locations along the data storage surface. In particular, the ramp surface has a carbon nitride or metal nitride material. A method is provided for applying a carbon nitride coating onto an organic polymer material. The method includes directing a nitrogen plasma at the surface of the organic polymer material.
Claims10
A disc drive data storage unit comprising:
- an actuator assembly comprising a suspension assembly supporting a head that facilitates data transmission, wherein the actuator assembly positions the head at selected locations;
- and
- a stationary ramp positioned to guide the head toward or away from a data storage disc, the ramp comprising a polymer, a ramp surface which coats the polymer comprising a composition, the composition comprising carbon nitride or metal nitride, the ramp spaced apart from the data storage disc proximate an outer radius of the disc.
