摘要： A disk drive has an actuator coil that includes first and second lateral legs joined by first and second longitudinal legs to form a closed coil periphery. The first lateral leg is disposed closer to the actuator pivot bore than the second lateral leg. The first and second longitudinal legs join the second lateral leg at a first interior bend location and at a second interior bend location within the closed coil periphery, respectively. A bobbin is disposed within the closed coil periphery and contacts the conductive coil at two locations (e.g. the first interior bend location and the second interior bend location). Preferably, the bobbin defines a total bobbin length and an average bobbin width, and the total bobbin length is at least 3 times the average bobbin width.

摘要： A disk drive head stack assembly includes an actuator arm tip that includes a swaging hole centered about a swaging axis. A first suspension assembly has a first swage boss that protrudes into the swaging hole. A second suspension assembly has a second swage boss that protrudes into the swaging hole and does not contact the first swage boss. Each of the first and second swage bosses includes an inner lip that extends radially closer to the swaging axis than any other part of that swage boss. The inner lip thickness of the first swage boss, measured parallel to the swaging axis, increases more greatly with increasing radial distance from the swaging axis than does the inner lip thickness of the second swage boss.

The sleeve can have a first contact surface that extends in a direction transverse to the axis. A spindle is rotationally received within the bore, and the spindle and the sleeve permit relative rotational movement when the spindle is positioned within the bore. The spindle has a stopper with a second contact surface that extends in a direction transverse to the axis when the spindle is positioned within the bore. A portion of at least one of the first and second contact surfaces includes a softer material than that of the spindle and the bearing sleeve, and the first and second contact surfaces are configured to engage each other upon relative axial movement between the spindle and the sleeve.

摘要： A pure rotary microactuator comprising a spring assembly etched within a silicon substrate is disclosed. A first piezoelectric device is coupled with a first portion of the spring assembly and a second piezoelectric device coupled with a second portion of the spring assembly. The first piezoelectric device changes shape in response to an electrical input signal, and this change in shape provides a first push force to the first portion of the spring assembly in a first direction. The second piezoelectric device also changes shape in response to the electrical input signal, and this change in shape provides a second push force to the second portion in a second direction, which is different from the first direction. The combination of the first and the second push forces rotates the spring assembly with respect to the silicon substrate.

摘要： A hard disk drive has a flexible cable and a flexible cable damper positioned adjacent to but separate from the flexible cable. The damper is a thin film loop with a damper patch that is completely independent of the flexible cable. The damper strip is a non-signal carrying substrate and has the constraint layer attached to it opposite the flexible cable. Both the damper and flexible cable extend in an arcuate configuration from the base to an integrated lead suspension tail extending from the actuator.
