Abstract
A disk drive assembly includes a load beam having a longitudinal centerline and a flexure attached to the load beam. The flexure includes deflectable tongue and a ring. The deflectable tongue includes a pad configured for mounting a slider having a trailing edge. The ring surrounds a trailing edge portion of the tongue and includes a catch. The tongue includes a plurality of limiters that are disposed symmetrically about the longitudinal centerline, that are bent from a plane of the pad, and that extend away from the slider. The plurality of limiters are configured to contact the catch to limit deflection of the slider. A method of limiting deflection of an air bearing slider in a z-direction is also described.

A disk drive head-gimbal assembly, comprising:
- a load beam having a longitudinal centerline;
- a flexure attached to the load beam and comprising:
- a deflectable tongue comprising a pad configured for mounting a slider having a trailing edge;
- and
- a ring surrounding a trailing edge portion of the tongue and comprising a catch;
- wherein the tongue comprises a plurality of limiters that:
- are disposed symmetrically about the longitudinal centerline;
- are bent from a plane of the pad;
- and
- extend away from the slider;
- wherein the plurality of limiters are configured to contact the catch to limit deflection of the slider.
A method of limiting deflection of an air bearing slider in a z-direction, the method comprising:
- obtaining the air bearing slider that is positioned on a longitudinal centerline of a load beam, wherein the load beam comprises rails, wherein the slider is mounted to a pad of a deflectable tongue of a flexure attached to the load beam, wherein the tongue comprises a plurality of limiters that extend upward and are positioned transversely outward of the rails of the load beam;
- and
- establishing physical contact between the plurality of limiters and a catch attached to a ring of the flexure.
