Claim:
A disk drive load/unload ramp, comprising: a body that includes a bottom mounting surface that defines a mounting surface plane and a protruding post that protrudes below the mounting surface plane and that is adapted to pivot in a recess of a disc drive base plate surface that is at the mounting surface plane; a first head load/unload section that is joined to the body and that includes a transition surface having first and second arcuate edges that extend between a camming surface and a locking section of the first head load/unload section, the locking section comprising a first protruding lift-tab-support ledge that defines a park position notch between the first ledge and the first head load/unload section; a second protruding ledge that is positioned to underlie the parked position notch in alignment with a head in a park position; a first air dam that extends outwardly from the body, the air dam abutting the first arcuate edge of the transition surface; a first disk extender that in turn comprises a disk extender surface, wherein when said disk drive load/unload ramp is installed in a disk drive, and 1) said first head load/unload section interacts with a corresponding head-gimbal assembly of the disk drive to move a head of the corresponding head-gimbal assembly away from its corresponding data storage disk of the disk drive during a parking operation; 2) said first air dam is aligned with and spaced from a primary data storage surface of at least one data storage disk of the disk drive; and 3) said disk extender surface is disposed beyond and aligned with a perimeter of a corresponding data storage disk of the disk drive and further is at least substantially parallel with the perimeter of its corresponding data storage disk.
