Abstract
A hard disk drive is provided with a ramp mechanism at the side of the disks for holding head sliders when the disks do not rotate. The ramp mechanism includes a ramp unit at least partially opposed to an outer edge of each disk medium. A roller provided in the ramp unit rotatably contacts the outer edge of the disk medium when the outer edge of the disk medium deflects with respect to its rotation axis.
Claims9
A ramp mechanism comprising:
- a ramp unit at least partially opposed to an outer edge of a disk medium that rotates about a rotation axis at a specific interval, holding a head slider that is flyable over said disk medium at a distanced position;
- and
- a roller provided in said ramp unit that rotatably contacts an outer edge of said disk medium when the outer edge of said disk medium deflects with respect to said rotation axis.
A magnetic disk apparatus according, comprising:
- a magnetic disk medium rotating about a rotation axis;
- a head slider having a head for data writing onto and reading from said magnetic disk medium;
- and
- a ramp mechanism for holding said head slider at a position distanced from said magnetic disk medium;
- wherein the ramp mechanism includes a ramp unit at least partially opposed to an outer edge of a disk medium that rotates about a rotation axis at a specific interval, holding a head slider that is flyable over said disk medium at a distanced position, and a roller provided in said ramp unit that rotatably contacts an outer edge of said disk medium when the outer edge of said disk medium deflects with respect to said rotation axis.
