摘要： Various air-actuated components of a disk drive are disclosed. For instance, an air-actuated load/unload ramp may be used by a disk drive and which is movable between a parked position and an operational position. An air-actuated ramp lock may be used by a disk drive to lock a movable load/unload ramp (e.g., one that may move between a parked position and an operational position). Finally, an air-actuated head positioner assembly may be used by a disk drive to lock a head positioner assembly in its parked position. In each of these cases, air currents generated by a rotation of one or more disks used by the disk drive provide the motive force for moving the noted air-actuated component at least generally from one position to another.

摘要： Isolation of an HDD production device such as a servo track writer from external vibration is provided. The isolated device and its nest or support are suspended in a fashion to allow one, two or three degrees of angular or rotational freedom of movement. The points of suspension are above the center of mass of the isolated device, alone or combined with its nest, and gravity will self-align the isolated device in the manner of an unforced pendulum. A relatively large moment of inertia for at least one direction of angular movement is provided, e.g., by positioning at least one suspension point spaced a relatively large distance from the center of mass to provide a large moment arm for such movement.
摘要翻译：提供了诸如伺服记录器的HDD制造装置的外部振动的隔离。隔离的装置及其巢或支撑件以允许一个，两个或三个角度或旋转自由度的方式被悬挂。悬挂点高于隔离装置的质量中心，单独或与其组合，重力将以非强制摆锤的方式自对准隔离装置。提供了至少一个角度运动方向的相对较大的惯性矩，例如通过将至少一个悬置点定位成与质心相隔较远的距离，以提供用于这种移动的大力矩臂。

摘要： Embodiments of the present invention are directed to methods of making a disk drive and related servo writers. The disk drive includes a data storage disk, an actuator arm, and a head connected to the actuator arm. The disk drive is connected to a servo writer that includes a push-arm that is configured to radially move the actuator arm relative to the disk. The method includes moving the push-arm of the servo writer a defined distance to push the actuator arm and position the head at a defined radial location on the disk. Servo fields are written through the head along an arc at the defined radial location on the disk. A sensor that contacts the actuator arm is used to generate an electrical vibration signal that is indicative of vibration between the push-arm and the actuator arm.
