  • Patent number: 7177119
    Abstract: A microactuated head suspension including a mounting region for attachment of the head suspension to a source of primary actuation, a pair of generally arcuate ring springs and a connecting member. The ring springs at spaced locations extending from the mounting region with at least one aperture interposed between the pair of ring springs. Each ring spring having concave sides that are substantially free from linear sections and are oriented away from a longitudinal centerline of the head suspension. The connection member is located opposite the mounting region and is spaced from the mounting region by the at least one aperture. The connection member joins ends of the pair of ring springs. In addition, the head suspension may include at least one microactuator for secondary actuation of the head suspension. The microactuator is operationally mounted relative to the pair of ring springs.

  • Patent number: 7149054
    Abstract: 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.
