Mounts for securing magnetic disk drive head suspensions to actuator arms. The mounts include structures that snap onto the actuator arm to provide a secure friction fit engagement. The mounts can be efficiently removed to permit rework of the suspension and head components.

Load beams for disk drive head suspensions having snap-on mounts comprising deflectable arms with spring tabs for engaging an aperture in the actuator arm

A baseplate for swaging a head suspension to an actuator arm includes a flange with an opening having a back bore diameter and a boss tower extending from the flange and having an outer diameter. The back bore diameter is less than or equal to about 105% of the outer diameter and greater than or equal to about 90% of the outer diameter.

Baseplate for a disk drive head suspension

A head suspension for a reverse flow disk drive. The head suspension includes a load beam having a mounting region at a proximal end, a rigid region at a distal end and a spring region between the mounting region and the rigid region. A flexure is mounted on the distal end of the rigid region. A slider is mounted on the flexure. The slider has a proximal end closest to the proximal end of the load beam, wherein the spring region, the rigid region, the flexure and the slider comprise an active portion. One or more read/write heads are located on the proximal end of the slider. A plurality of electrical traces extend along the head suspension to the proximal end of the slider. At least one airflow attenuator is provided that creates a region of reduced airflow velocity proximate at least a portion of the active portion. An actuator assembly and to a reverse flow disk drive are also disclosed.

Reverse flow disk drive and head suspension for same

A baseplate for swaging a disk drive head suspension to an arm having a thickness and a neutral axis. The baseplate includes a boss tower having an outer diameter high point configured to be located within about &#xb1;6% of the arm thickness from the neutral axis when swaged to an arm.

Swaging-optimized baseplate for disk drive head suspension

A head suspension or head suspension component article configured for solder ball bonding of a head slider to electrical traces on article. The article including electrical traces formed from electrically conductive material with the electrical traces having a bonding region adapted for electrical bonding to a head slider. Also included is a support structure providing support for at least portions of the electrical traces and including a head slider mounting region adapted to receive the head slider. This structure is configured to mechanically and thermally isolate the bonding region of the electrical traces from the head slider mounting region to reduce mechanical and thermal effects of a solder ball bonding process on the article during solder ball bonding of the head slider to the electrical traces. The support structure may be reduced at or around the bonding region, or the conductive material may be increased to dissipate more heat.

Head suspension configured for improved thermal performance during solder ball bonding to head slider

A shock limiter system for a head suspension configured to engage with an external structure in a rigid disk drive. The head suspension has a flexure with a head slider oriented in a first direction over a disk surface. The head suspension includes a load beam having a mounting region, a rigid region and a spring region located between the mounting region and rigid region. The rigid region and the flexure define a distal region of the head suspension. The shock limiter system comprises a shock limiter extending from the distal region in a second direction generally opposite the first direction. The shock limiter is positioned on the distal region to engage with the external structure to limit movement of the head suspension away from the disk surface during a shock event.
