Embodiment Construction

[0041] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings.

[0042] Fig. 3 is a perspective view of a hard disk drive device including a plurality of head suspensions of the present invention. This hard magnetic disk driving device comprises: a plurality of hard magnetic disks 21 all recording data on each; A main motor 22 in order to rotate the hard magnetic disk 21; A voice coil motor 24 with an oscillating actuator 23 ; a cover 31 and a housing 30 including a base portion 32 . The components 21 , 22 , 23 , 24 , etc. are accommodated in the case 30 .

[0043] The hard magnetic disk 21 is fixed to the rotor of the main motor 22 and rotates around the main shaft. The surface of each hard magnetic disk 21 includes: a data area of ​​a plurality of tracks formed coaxially, on which data including servo data is to be recorded; a CSS area to which the magnetic head slider 3 is moved when the hard magnetic disk drive de...

Abstract

A head suspension is described, which can be assembled without damaging the head element. In the head suspension, a rigid section holds a head slider which writes data on and reads data from a disk. The rigid section is capable of bearing an external force whose direction is perpendicular to a recording face of the disk. A spring section has elasticity in the direction perpendicular to the recording face of the disk. An anti-vibration member is provided in the spring section, the anti-vibration member at least partially defines an opening over the spring section. With this structure, a change in the elasticity of the head suspension can be maintained within an appropriate range, transmission of vibration to the head slider can be restricted, and the head slider can be floated stably.

Description

technical field [0001] The present invention relates to head suspensions and disk drives for securing head sliders, and more particularly to head sliders, which include an anti-vibration structure that limits vibrations transmitted to the head slider and limits the manufacturing process Electrostatic interference in and also relates to a magnetic disk drive device comprising the above-mentioned magnetic head suspension. Background technique [0002] In magnetic disk drives such as hard disk drives and magneto-optical disk drives, the head slider floats while the disk rotates. The magnetic head is mounted on the magnetic head slider and records data on the magnetic disk or reads data from it. Recently, in order to increase the recording density of magnetic disks, the height of the head slider has been lowered, and the size of the magnetic head has been reduced. In such a magnetic disk drive apparatus, it is important to limit the vibration of the head slider held by the hea...
