ABSTRACT:
A spacer structure is proposed, including a transducer parking structure, for use in a disk drive assembly including a housing, a rotatable disk, and an actuator assembly for positioning a transducer relative to the rotating disk. In the preferred embodiment, the spacer structure is adapted for contact with, or ridged mounting to, the housing of a disk drive over a disk. The spacer structure may be further adapted for making contact with the disk surface, e.g. by the provision of a cone-like or needle-like protrusion. The point of contact is preferably made at a substantially planar region at the center of the disk. The planar region may form a part of the spacer structure, and may be coated, textured, or smooth. It may also be stationary with respect to the rotating disk, or may rotate with the disk, enabling the spacer structure to be rigidly affixed. The parking structure may be a recess or cavity, a ramp, a step, or a combination of these structures. The ramp may be adapted to engage a transducer-supporting suspension of the disk drive actuator assembly.
