A clamping structure for disk drive for receiving a disk includes a spindle hub, a spacer, and a clamp ring. The spindle hub has a flange at a first end thereof. The flange has a first protruding portion. The discs are stacked on the first protruding portion. The first spacer is interposed between adjacent ones of the disks. The clamp ring is fixed to a second end of the spindle hub. The clamp ring has a second protruding portion for biasing the disks toward the flange of the spindle hub. In a process of forming a holder arm of the disk drive, the tip of a holder arm is contoured by wire cutting method after the holder armed is roughly formed from a metal body. In the wire cutting method, a voltage is placed between the metal body and the wire. The tip of the holder is contoured by the wire by bringing the wire into contact with the metal body.

Magnetic disk drive having means for reducing disk deformation

A process for reducing deformation of a holder arm, which holds a head of a data recording device, includes cutting a metal body to form the holder arm and contouring a tip of the holder arm by wire cutting. The step of contouring preferably includes steps of placing a voltage between the metal body and a wire, moving the wire, and bringing the wire adjacent the metal body to contour the tip of the holder arm.
