Problems solved by technology

[0006] However, if the through hole is formed in the region near the hinge on the beam portion, due to the influence of the air on the disk surface on the through hole (wind force correction amount or air turbulence), especially in a disk drive in which the disk rotates at a high speed, The beam section will vibrate

Embodiment Construction

[0026] A first embodiment of the present invention will now be described with reference to FIGS. 1 to 3 . image 3 The hard disk drive (HDD) shown includes a bracket 12 which is rotatable about an axis 11 . Carriage 12 is rotated about shaft 11 by a position controlled motor 13, such as a voice coil motor. Mounted on the bracket 12 are arms (actuating arms) 16, suspensions 17 each mounted on each end portion of the arm 16, a head 18 mounted on each end portion of the suspension 17, and the like. When the carriage 12 is driven by the motor 13, the head 18 moves to the desired track of the magnetic disk 19.

[0027] The head 18 includes a slider 20 positioned to face the recording surface of the magnetic disk 19, and a sensor (not shown) fixed to the slider 20. When the disk 19 rotates at high speed, air enters the space between the disk 19 and the slider 20 and rises slightly away from the disk 19, thereby forming an air cushion between the disk 19 and the slider 20.

Abstract

The hanger bracket for magnetic disc drive includes base part, beam part and hinging part to connect the base part and the beam part. One rigid hole is formed in the area near the hinging area to lower the beam part and its opening is covered with one covering plate.

Description

technical field [0001] The present invention relates to a suspension for a disk drive mounted in an information processing device such as a personal computer. Background technique [0002] A hard disk drive (HDD), which is used to record and read information on rotating magnetic or magneto-optical disks, includes a chassis that rotates about an axis. The bracket is rotated around the shaft by a position control motor. The bracket is provided with an arm (actuating arm), a suspension mounted on the end portion of the arm, including the head of the slider mounted on the suspension, and the like. When the disk rotates at high speed, the slider rises slightly on the surface of the disk, thereby forming an air cushion between the disk and the slider. The suspension includes a bottom with a bottom plate, a beam portion formed of a high-precision leaf spring, and a flex portion fixed to the beam portion by laser welding or the like. The base plate is fixed to the suspension moun...
