Abstract
A magnetic disk apparatus has a plurality of spacers for connecting to a pivot shaft one ends of suspension arms for supporting sliders such that the suspension arms are separated from each other. Each spacer has a first section engaged with the pivot shaft, a second section connected to a suspension arm and a through-hole extending through the two sections. The first section of the spacer is deformed to frictionally grip the pivot shaft. The spacer is provided with a weakened section for preventing the deformation of the first section from being propagated to the second section.
Claims7
A magnetic disk apparatus comprising:
- a plurality of magnetic disks arranged parallel to each other;
- means for supporting and rotating said magnetic disks;
- sliders arranged close to the surfaces of said magnetic disks;
- suspension arms each supporting one of said sliders at one end thereof;
- a pivot shaft for rotating said suspension arms;
- and
- a plurality of spacers respectively connecting the other ends of said suspension arms to said pivot shaft, wherein each of said spacers includes a first section engaged with said pivot shaft, a second section connected to said suspension arm, and a through-hole extending through these two sections, said pivot shaft extending through said through-hole, said through-hole including a first hole section disposed in said first section and a second hole section disposed in said second section, communicating with said first hole section and having a diameter larger than the outer diameter of said pivot shaft, said first section of said spacer being deformed to frictionally grip said pivot shaft, each of said spacers being provided with means for preventing the deformation of said first section from being propagated to said second section.
