Abstract
A hard disk drive and head gimbal assembly including a flexure finger with a micro-actuator split of the flexure supporting a micro-actuator control line, leading to minimized gimbal width for the flexure finger about the micro-actuator assembly including the coupled slider and micro-actuators to reduce mechanical vibrations caused by wind off of a rotating disk surface accessed by the slider.
Claims18
A hard disk drive, comprising:
- a disk base;
- a spindle motor and a voice coil motor mounted on said disk base;
- said spindle motor rotating a disk creating at least one rotating disk surface with data stored on said rotating disk surface;
- said voice coil motor coupling through an actuator arm to at least one head gimbal assembly, wherein said head gimbal assembly, comprises
- a slider for accessing said rotating disk surface coarsely positioned by said voice coil motor;
- at least one micro-actuator coupled to said slider to create a micro-actuator assembly to finely position said slider for accessing said rotating disk surface;
- and
- a flexure finger electrically coupled to said micro-actuator assembly to provide at least one micro-actuator control line to said micro-actuator;
- wherein said flexure finger includes a micro-actuator flexure split separating said flexure for reducing mechanical vibration of said slider from wind induced by said rotating disk surface.
