Abstract
A slider and micro-actuator assembly of the present invention comprises a substrate having a trailing edge and a leading edge opposite the trailing edge; a read/write transducer formed at the trailing edge of the substrate and a piezoelectric micro-actuator formed at the leading edge of the substrate. The piezoelectric micro-actuator connects with the leading edge of the substrate via two spaced insulation layers so as to form a space between the piezoelectric micro-actuator and the leading edge of the substrate, the substrate with the read/write transducer rotates against a center thereof when the piezoelectric micro-actuator is driven to generate a rotation torque to the substrate via the space. The structure of the slider and micro-actuator assembly prevents the read/write transducer from damaged and gets better operation performance when the piezoelectric micro-actuator is driven. The present invention also discloses a method for manufacturing a slider and micro-actuator assembly, a HGA with the slider and micro-actuator assembly and a disk drive unit having such HGA.
