摘要： A method for monitoring the operability of a slider of a disk drive includes the steps of providing a slider that includes a read/write head that magnetically interacts with a storage disk, and a slider mover that adjusts a head-to-disk spacing, controlling an electrical stimulus to the slider mover with a drive circuitry, measuring an actual electrical response from the slider mover with the drive circuitry, and comparing the actual electrical response to an expected electrical response to determine an operability status of the slider mover. Further, changes in the actual electrical response can be monitored and used to predict future failure of the slider mover.

摘要： An apparatus and method for rotating an optical element, such as a diffraction grating or mirror, utilizes a moving coil actuator and an optical encoder to provide precise element position control. The moving coil actuator, which is coupled to the optical element, is comprised of a coil immersed in a magnetic field created by a pair of magnets. Current flowing in the coil windings causes the coil, and ultimately the optical element, to rotate. An optical encoder monitors the rotation of the element and provides rotation signals representative of the instantaneous element position to an actuator control circuit. The actuator control circuit phase shifts the rotation signals and compares the phase shifted rotation signals to a desired reference signal to generate position and velocity error signals. In a track follow mode, the position error signal is applied to the moving coil actuator via a loop compensator. When the apparatus is operating in an optimal seek mode, a trajectory generator receives the velocity error signals and generates an optimum velocity signal based on a preprogrammed velocity curve. The optimum velocity signal is then applied to the moving coil actuator via the loop compensator.

摘要： A transducer for indicating position in space with reference to a coordinate system includes a magnetic field source (13), a movable button element (11) composed of a magnetically susceptible material having a central pole face (16) and a surrounding annular co-planer pole face (19) for providing uniform magnetic flux paths in the annular region between and extending from the plane of the respective pole faces, and a probe element having a plurality of sensor units (41a-d) for electronically measuring magnetic flux through a plurality of separate, geometrically congruent areas arranged around an axis of symmetry (24) in a sensing plane which is spaced from, and parallel to that of the pole faces of the movable button element. The relative position of the button element in a plane perpendicular to the axis of symmetry is determined by electronically adding and subtracting the different measurements of magnetic flux through the respective areas, while the relative proximity of the sensing plane of the probe element to the pole face plane of the button element is determined from total magnetic flux measured by all of the sensors.

摘要： A positioning system for moving a member between positions in time optimal fashion employs concurrent "feedforward" and "feedback" control. The feedforward control system provides major control and the feedback control system provides minor control to correct for deviations between the actual and a nominal system. The feedback loop may thus be of low bandwidth permitting desensitization to high frequency disturbances or the employment of inherently low bandwidth controlled variables.The "feedforward" control function includes successive portions of opposite polarity corresponding to acceleration and deceleration of the member and also includes a subtractive velocity related component. This function represents the approximate current input to an electromagnetic coil actuator of a nominal system required to move such a member between positions in time optimal fashion.

摘要： A disk drive includes a drive housing, a storage disk, a slider and a drive circuitry. The slider magnetically interacts with the storage disk, and includes a read/write head that is positioned to have an actual head-to-disk spacing greater than zero nanometers during rotation of the storage disk. The drive circuitry can determine and/or monitor the actual head-to-disk spacing at any time during the operation of the disk drive based on an amplitude or a change in the amplitude of a signal such as a variable gain amplifier signal. In one embodiment, the slider includes a slider mover that receives current via the drive circuitry and causes a deformation of a portion of the slider to change the head-to-disk spacing based on the amplitude of the signal. In another embodiment, the read/write head moves during substantially consistent rotational velocity of the storage disk from a first actual head-to-disk spacing equal to approximately zero nanometers, to a second actual head-to-disk spacing that is greater than zero nanometers based on a desired amplitude of the signal.
