Active fly height control crown actuator

A data storage device comprising:

• a slider that defines an air bearing surface;
• a resilient hinged mounting structure;
• a microactuator comprising a top side and an underside to perform fine positioning movement when a control voltage is applied to the microactuator;
• the top side of the microactuator is secured to the hinged mounting structure;
• the underside of the microactuator is secured to the slider;
• and
• a control system that generates the control voltage, wherein the control voltage comprises a first electrical signal to regulate the fly height and a second electrical signal to regulate fine track following;
• wherein the microactuator enables the air bearing surface of the slider to be crowned for fly height controllability by applying a variable voltage.

A head gimbal assembly for use in a data storage device that includes a slider that defines an air bearing surface, comprising:

• a suspension having a flexure extending outward therefrom, the flexure comprising a resilient hinged mounting structure, wherein the mounting structure comprises a pair of hinged tabs disposed in gaps in the mounting structure and opposite each other relative to a center of symmetry;
• a microactuator comprising a top side and an underside, that moves rotationally about a center of rotation, to perform fine positioning movement when a control voltage is applied to the microactuator;
• the top side of the microactuator is secured to the hinged mounting structure with at least one bonding pad on each of the hinged tabs;
• the underside of the microactuator is secured to the slider;
• and
• a control system that uses a DC voltage to regulate the fly height and an AC voltage to regulate fine track following;
• wherein the microactuator enables the air bearing surface of the slider to be crowned for fly height controllability by applying a variable voltage.
