Abstract: A rotary microactuator includes a stationary structure formed on a substrate, a movable structure, and at least a pair of wires connected to the movable structure that conduct a signal associated with the movable structure. Each wire of the pair of wires has a first end that is connected in a cantilever manner to the substrate and a second end that is connected to the movable structure. The wires each have a serpentine shape between the first end and the second end, a predetermined spring stiffness, and a predetermined electrical characteristic. The microactuator also includes a magnetic head slider that is attached to the movable structure, and at least another pair of wires conducting a signal associated with a magnetic head of the slider. Each of the another pair of wires has a first end that is connected in a cantilever manner to the substrate and a second end that is connected to the movable structure. Like the first pair of wires, each of the another pair of wires has a serpentine shape between the first end and the second end of the wire. Electronic circuitry for conditioning the electrical signals associated with the magnetic head can be fabricated as part of the substrate and be connected to one of the pair of wires. The electronic circuitry can, for example, amplify electrical drive signals associated with the magnetic head, be a recording sensor preamplifier, and/or provide ESD protection for the electrical signals associated with the magnetic head.

Abstract: A method and apparatus for controlling a multiple-stage actuator for a disk drive which does not require an additional sensor for measuring the relative position between adjacent actuator stages. In a two-stage actuator system, a position-type secondary actuator (SA) rides piggyback on a primary actuator (PA). The repeatable runout is measured and used as a feedforward signal to the PA. If the PA is a rotary actuator, the feedforward signal is preferably arc corrected for the arc that the head transverses from the inner radius to the outer radius of the disk. Added to the feedforward signal is the moving average of the drive signal applied to the SA. Because the SA is of the position-type having a neutral position, this moving average is proportional to the time cumulative drift present in the two-stage actuator system, and forces the PA in a direction that minimizes deviation of the SA from its neutral position. This minimizes the range requirement for the SA, the main purpose of which is to reduce non-repeatable runout.

Abstract: A motor based on the wobble motor provides pure rotary motion and can be used as a spindle motor for very small disk drives. The primary components of the motor are fabricated using thin film processes. The rotor has inner and outer rings that are interconnected by flexible members, such as semicircularly-shaped spring elements, with the rings and flexible members being formed of the same material. The rotor resides within the wobble motor stator elements that are circumferentially spaced on a substrate. The inner rotor ring is supported by a bearing structure that may be a ball bearing assembly or a pin bearing comprising a post and a restraining cap. The outer rotor ring functions as the wobble motor rotor and rolls around the inside of the stator as the stator elements are sequentially electrostatically activated. The flexible members act as a transmission to convert the wobble motion of the outer rotor ring to pure rotary motion of the inner rotor ring. The motor can function as a disk drive spindle motor by attachment of a data recording disk to the inner rotor ring and use of appropriate control circuitry to drive the motor at constant speed. The disk drive actuator may be attached to the same substrate that supports the stator elements. The stator elements, the rotor, and the bearing assembly may all be fabricated on a suitable substrate using thin film processes, without the necessity of assembly of separate components.

Abstract: A compact high aspect ratio MEMS optical switch, and a process for fabricating same, are disclosed. An outer body portion is mounted so as to have a first rotational degree of freedom about a first axis. An inner body portion is coupled mechanically to the outer body portion so as to have a second rotational degree of freedom relative to the outer body portion about a second axis, the second axis being substantially perpendicular to the first axis and in the plane of the outer body portion. The inner body portion is further coupled to the outer body portion in a manner such that the inner body portion rotates with the outer body portion about the first axis if the outer body is rotated about the first axis, such that the second axis remains substantially in the plane of the outer body portion as the outer body portion rotates about the first axis. An outer electrostatic actuator is configured to rotate the outer body portion about the first axis when an electrostatic force is applied to the outer electrostatic actuator. An inner electrostatic actuator is configured to rotate the inner body portion relative to the outer portion about the second axis when an electrostatic force is applied to the inner electrostatic actuator. The outer body portion, inner body portion, outer electrostatic actuator, and inner electrostatic actuator are formed in just two structural layers. In one embodiment, the inner body portion comprises a metal substrate on which a metal payload, such as an optical mirror, is formed.
