Claims
- 1. A disk drive apparatus for storing information comprising:
- a housing providing a base for mounting components of said disk drive;
- at least one disk rotatably mounted on said housing;
- an actuator attached to said housing, said actuator having a first end and a second end, and pivoting about an axis parallel to the axis of rotation of said disk;
- a head attached to said first end of said actuator;
- a coil attached to the second end of said actuator;
- a first permanent magnet for creating a magnetic field surrounding said coil, said field used for positioning said actuator;
- wherein said housing has a first opening therein near said coil, said first permanent magnet being positioned within said first opening and attached to the outside of said housing opposite said coil.
- 2. The disk drive apparatus of claim 1, further comprising:
- a second permanent magnet for creating said magnetic field surrounding said coil;
- wherein said housing has a second opening therein near said coil on a side opposite the first opening, said second permanent magnet being positioned within said second opening and attached to the outside of said housing opposite said coil.
- 3. The disk drive apparatus of claim 1, wherein said first magnet is mounted directly to a flat yoke, said yoke being attached to the outside of said housing opposite said coil.
- 4. A disk drive apparatus for storing information comprising:
- a housing providing a base for mounting components of said disk drive;
- at least one disk rotatably mounted on said housing;
- an actuator attached to said housing, said actuator having a first end and a second end, and pivoting about an axis parallel to the axis of rotation of said disk;
- a head attached to said first end of said actuator;
- a coil attached to the second end of said actuator;
- a first permanent magnet for creating a magnetic field surrounding said coil, said field used for positioning said actuator, wherein said housing has a first opening therein near said coil, said first permanent magnet being positioned within and substantially filling said first opening, said first permanent magnet being attached to said housing;
- a flat yoke, said first permanent magnet being mounted directly to said flat yoke, said yoke being attached to the outside of said housing opposite said coil, wherein said yoke is larger than said opening and overlaps said opening.
- 5. The disk drive apparatus of claim 4, wherein said housing includes a relief surrounding said opening, said relief having a depth, said yoke abutting said relief, wherein the depth of said relief coincides with the height of said yoke.
