Abstract

The invention discloses a slider tab combination which comprises: slider and micro-actuator; wherein the micro-actuator comprises base arms, movable arm and two side arms that take the axial of base arm as axis of symmetry and are connected with the base arm and movable arms, and at least one piezo-electric chip connected with one of the side arms; suspension component for supporting the slider and micro-actuator. The slider is positioned on the movable arm and rotated by the movable arm when the at least one piezo-electric chip is activated. The invention also discloses a hard disk driver structure that uses the slider tab combination.

Description

technical field [0001] The invention relates to a disk drive, in particular to a micro drive and a magnetic head tab assembly using the micro drive. Background technique [0002] A disk drive is an information storage device that uses magnetic media to store data. refer to Figure 1a , the existing typical disk drive (Disk Drive) includes a disk and a drive arm for driving the head gimbal assembly 277 (Head Gimbal Assembly, HGA) (the head gimbal assembly 277 is provided with a suspension member with a magnetic head 203 (not marked)). Wherein, the magnetic disk is mounted on a spindle motor for driving the magnetic disk to rotate, and a Voice-Coil Motor (Voice-Coil Motor, VCM) is used to control the movement of the driving arm, thereby controlling the magnetic head 203 to move from one magnetic track to the other on the surface of the magnetic disk. next track to read or write data from the disk. [0003] However, during the travel of the magnetic head 203, due to the inhe...
