摘要： A microactuation system selectively alters a position of a transducing head carried by a slider in a disc drive system with respect to a track of a rotatable disk having a plurality of concentric tracks. The microactuation system includes a head suspension having a first portion and a flexure for supporting the slider. A flexible beam extends from the first portion of the head suspension at one end to the flexure at the other end. An electroactive element is attached to the beam. The electroactive element bends in response to a control signal applied thereto. The beam is sufficiently compliant to permit movement of the first portion of the head suspension with respect to the flexure.

摘要： An actuator arm design having a close cross section which greatly improves the performance of the disc drive. The actuator arm is formed of a top skin, a bottom skin, and a core. The core may be formed of a corrugated metal, or a foam metal, or a combination of the two. As a result of this structure of the arm, the arm is highly stiff, yet low mass which yields an arm having a high resonant frequency.

摘要： A flow control device for a data storage system to reduce flow induced vibration. The flow control device includes a plurality of streamline flow passages to reduce turbulent flow in a flow field along a disc surface. Thus, air flow induced by rotation of data discs is directed through the plurality of streamline flow passages to reduce turbulence to limit excitation or vibration of the head and suspension components.

摘要： A magnetic disc drive includes a base, a disc rotatably attached to said base, and a ramp attached to the base near said disc. The magnetic disc drive also has an actuator assembly pivotably attached to the base. The actuator assembly rotates about an actuator pivot point. The actuator assembly further includes a suspension attached to one end of the actuator assembly, and a transducer attached to the suspension. The actuator assembly moves the transducer between a transducing position and an unload position. The suspension includes a lift tab which contacts the ramp at a contact point as the transducer is moved to the unload position. As the actuator assembly moves the transducer to the unload position, the contact point moves toward the actuator pivot point. This results in a change of the resonant frequency of the actuator assembly. The resonant frequency is lower when the transducer is near the end of the ramp proximate the disc. The ramp can have a straight or a curved lift tab contact path.

摘要： A slider having a slider body is provided for actively controlling a fly height of the slider relative to a data storage disc. A first plurality of beams are affixed to a back surface of the slider body. The beams are disassociated from one another and are constructed of deformable material. Each beam, in response to an applied electrical control signal is deformable in a first dimension parallel to the back surface of the slider body. Deformation of the first plurality of beams in response to an applied electrical control signal affects slider fly height by changing one of slider body crown and cross curvatures to a greater extent than along the other. In accordance with other embodiments, multiple layers of deformable beams are attached to a slider. In yet other embodiments, piezoelectric material layers having anisotropic properties are substituted for beam layers.

摘要： A head gimbal assembly (HGA) for use in a forward flow disc drive includes a load beam having a longitudinal axis, a gimbal, a slider, and an air deflector. The gimbal is mounted to a distal end of the load beam. The slider includes a transducing head and is mounted to a disc side of the gimbal and is aligned with the longitudinal axis of the load beam. The air deflector includes a first deflecting member that is positioned upstream of the slider relative to a forward airflow. The air deflector extends from a disc side of either the distal end of the load beam or the gimbal and across the longitudinal axis. The air deflector deflects a portion of the forward airflow away from the slider to thereby reduce windage induced off-track motion of the transducing head.

摘要： A microactuation system selectively alters a position of a transducing head carried by a slider in a disc drive system with respect to a track of a rotatable disk having a plurality of concentric tracks. The microactuation system includes a head suspension having a first portion and a second portion coupled by one or more flexible hinges. An electroactive element is attached to the first portion of the head suspension at one end and the second portion of the load beam at the other end. The electroactive element bends in response to a control signal applied thereto. The hinge is sufficiently compliant to permit movement of the first portion with respect to the second portion of the head suspension.
