    摘要： Disclosed herein is a magnetic disk drive including a spindle shaft fixed to a base, a coil mounted on the spindle shaft, a spindle hub rotatably mounted on the spindle shaft, a magnetic disk fixed to the spindle hub and having a plurality of tracks, a permanent magnet fixed to the spindle hub, a magnetic head for reading/writing information from/to the magnetic disk, and an actuator for moving the magnetic head across the tracks of the magnetic disk. The magnetic disk drive further includes a cover fixed to the base and having a hole at a position corresponding to the spindle shaft, a first metal washer placed on the cover at a portion around the hole, a second metal washer for sandwiching the cover at the portion around the hole in cooperation with the first metal washer, and a screw for securing the first and second metal washers to the spindle shaft.

    摘要： A recording disk apparatus includes a recording disk supported by a rotation axis. A clamp is fixed at the tip end of the rotation axis by screws so as to urge the recording disk against a flange at the base end of the rotation axis. The screws are disposed along an imaginary circle concentric to the rotation axis so as to fix a plane body of the clamp at the tip end of the rotation axis. A rigidity reduction mechanism reduces rigidity of the plane body at an intermediate area relative to the screw bore areas, which intermediate area is defined between the screw bore areas along the imaginary circle. The rigidity reduction mechanism serves to suppress the undulation of the magnetic disk.
