Disk drive apparatus

A disk drive apparatus comprising:

• a hard disk having a diameter less than or substantially equal to 2.5 inches;
• a spin motor for rotating said hard disk, said spin motor including a magnet made of a material including a rare earth and having an energy product in excess of 30 million gauss-oersteds, said spin motor having a height dimension of less than approximately 0.4 inches;
• a transducer for communicating with said hard disk;
• a rotary actuator for moving said transducer relative to said hard disk, said rotary actuator including a pivot capstan, a voice coil and a magnet in a stacked relationship having a height dimension of less than 0.35 inches;
• a housing for containing said hard disk, said spin motor, said transducer and said rotary actuator in an interior thereof, said housing having an exterior surface, an interior surface, a hole extending from said exterior surface to said interior surface, a first top side and a first bottom side, wherein said hole is helically-shaped;
• a desiccant in communication with said interior and located intermediate said interior surface and said exterior surface of said housing;
• a printed circuit board having a second top side and a second bottom side;
• electronic means for controlling said spin motor, said transducer and said rotary actuator, said electronic means includes a first component of a first height, a second component of a second height greater than said first height, and a third component having a third height, said first and second components located on said second top side of said printed circuit board and said third component located on said second bottom side of said printed circuit board;
• and
• frame means for connecting said housing to said printed circuit board in a stacked relationship where said first bottom side of said housing faces said second top side of said printed circuit board, wherein said frame provides side, bottom and top mounting capability and wherein said disk drive apparatus has a foot print of approximately 2.8 inches by approximately 4.0 inches and a height dimension of approximately 0.630 inches or less;
• wherein a first cross-section of said disk drive apparatus includes only said first top side of said housing, one of the following:
• said spin motor and said pivot capstan, and said printed circuit board, where said first cross-section is less than or equal to 0.630 inches in height;
• wherein a second cross-section of said disk drive apparatus includes said first top side of said housing, said voice coil assembly, said first bottom side of said housing, said first component, said printed circuit board and said second component, wherein said second cross-section is less than or equal to 0.630 inches in height;
• wherein a third cross-section of said disk drive apparatus includes said first top side of said housing, said hard disk, said first bottom side of said housing, said second component, said printed circuit and said third component, wherein said third cross-section is less than or equal to 0.630 inches in height.
