Disk drive head suspension with a dual dimple and a flexure tongue with a piezoelectric microactuator
摘要:
A disk drive head gimbal assembly (HGA) includes a distal region that includes a load beam dimple having a protruding convex surface. The HGA includes a laminated flexure having a structural layer with a tongue disposed between two outrigger beams. A piezoelectric element is adhered to the tongue. The tongue includes an actuated portion to which a read head may be adhered, and that is rotated about an axis of rotation by expansion of the piezoelectric element. The tongue also includes a non-actuated portion that is not rotated by expansion of the piezoelectric element. The non-actuated portion of the tongue adjoins and forms a bridge between the two outrigger beams. The bridge includes a flexure dimple that protrudes from the tongue and has a concave surface that is in contact with the convex surface of the load beam dimple.
