ABSTRACT:
A magnetic disk device has a spindle hub fixed to a spindle shaft. The spindle hub includes a flange member formed at its lower end portion and an annular groove formed in the flange member. A plurality of magnetic disks and spacer rings are stacked alternately on the flange member of the spindle hub in an axial direction. A cylindrical support member disposed in the annular groove of the spindle hub to form a predetermined gap between its inner peripheral surface and an outer peripheral surface of the spindle hub, while an outer peripheral surface of the cylindrical support member contacts the inner peripheral surfaces of the plurality of magnetic disks and spacer rings. Another magnetic disk device has a spindle hub fixed to a spindle shaft. The spindle hub includes a flange member formed at its lower end portion and has at least two grooves formed on its outer periphery at a predetermined distance apart. A plurality of magnetic disks and spacer rings are stacked alternately on the flange member of the spindle hub in an axial direction. A cylindrical support member is interposed between the plurality of magnetic disks and spacer rings and the spindle hub to form a predetermined gap between its inner peripheral surface and an outer peripheral surface of the spindle hub, while an outer peripheral surface of the cylindrical support member contacts the inner peripheral surfaces of the plurality of magnetic disks and spacer rings. A resilient member is disposed in each of the grooves, and each resilient member contacts the inner peripheral surface of the cylindrical support member.
