Abstract
Embodiments of the present invention provide a structure of a pivot receiving surface which may excellently adjust the attitude of a head supporting mechanism in a magnetic disk drive. In one embodiment, three projections are formed at a base for supporting a pivot assembly. The first projection is formed on a first line which bisects an angle defined between a second line and a third line determining a range, in which a head/slider flies above a magnetic disk. In contrast, the other two projections are formed at positions apart from the first projection at an angle of 120°, respectively. The attitude of the pivot assembly is adjusted by adjusting the heights of the projections, and thus, a head supporting mechanism is corrected in a predetermined attitude within the range in which the head/slider flies above the magnetic disk.
