摘要： A disk drive controller having a microprocessor and a sampled signal head positioning system measures and stores the relative rotational offsets between heads arranged in a stacked relationship and respective servo wedges on different disk surfaces. The offsets are stored in a table and subsequently applied to a servo wedge detection circuit to ensure that a next sequential wedge is detected after a head switch.

摘要： A mounting system for mounting an expansion card inside a computer chassis includes a mounting bracket having a combination board mounting clip and chassis mounting tab formed as an integral unit in which the bracket releasebly fastens to a corner of the expansion card. The expansion card has a bottom edge connector for plugging into an expansion card socket at the base of the computer chassis inside the expansion slot. The computer chassis also has a removeable cover plate on a panel of the chassis for shielding the expansion slot. The board mounting clip releasably fastens to the expansion card by engaging the opposite faces of the board in a continuous frictional means of attachment without the use of external fastening means. The chassis mounting tab is arranged so that when the expansion card is plugged into the expansion card socket, a portion of the chassis mounting tab automatically registers with the fastener for the cover plate so that the fastener is usable to fasten the tab to a portion of the chassis adjacent the cover plate, with the cover plate providing a separate means of shielding the expansion slot, independently of the bracket on the expansion card.

摘要： A digital-to-analog converter (DAC) is preferably employed to receive a digital input word and provide an analog output signal to a motor driver in a disk drive servo. The digital input word has a plurality of bit positions for establishing a resolution for the DAC. These bit positions define first and second groups of bits. The DAC comprises circuitry responsive to the first group of bits for producing a pair of analog signals defining a common-mode magnitude and a differential magnitude. The common-mode magnitude is a function of the value of the first set of bits and the differential magnitude is a function of the number of bit positions in the first group of bits. In the DAC: a clock generates a clocking signal; a state machine has an input for receiving the clocking signal, an input for receiving the second groups of bits, and an output for providing a time-varying control signal; switching circuitry has a pair of inputs for receiving the pair of analog signals, an input for receiving the time-varying control signal, and an output for providing a pulse-width and amplitude modulated signal; and averaging circuitry responds to the pulse-width and amplitude modulated signal to producing the analog output signal.

摘要： An apparatus for sensing relative positions of mechanically coupled devices. The apparatus includes a magnetically actuated switch connected to a set of flux conductors to form a switch assembly. A permanent magnet is affixed to a set of flux conductors to form a magnet assembly. The flux conductors are positioned adjacently to conduct flux from the permanent magnet to the magnetically actuated switch. Movement of either assembly results in the reduction of flux conduction between the magnet and the magnetically actuated switch. The apparatus can be integrated into a helmet mount for night vision goggles to sense the relative position of the helmet mount for controlling the operation of the night vision goggle.

摘要： A split actuator comprising two spring coupled actuators that share a common pivot bearing. The two reduced inertia actuators permit overlapping motions during a seek operation thereby reducing dead times in transfer of data between disk and transducers disposed on the actuators. A spring member that spring couples the two actuators boosts relative motions by storing and releasing spring potential energy selectively. The spring member is also configured so as to substantially restrict the relative motions of the two actuators to rotational motions about a common axis of the common pivot bearing. Rigidity of the spring member to non-rotational relative motions, as well as tuning of the spring member to provide a rigid response to selected frequencies, the spring member in conjunction with the common pivot bearing result in mechanical disturbance being substantially common to the two actuators, thereby allowing predictable and manageable disturbance corrections.

摘要： A disk drive is disclosed comprising a velocity extraction circuit for extracting a velocity of an actuator arm from a back EMF voltage across a voice coil of a voice coil motor when embedded servo information is unavailable. The velocity extraction circuit comprises a dual slope integrator for integrating a voltage representing a current flowing through the voice coil and the voltage across the voice coil. The sum of the integrations cancels the resistance of the voice coil from the back EMF measurement. In one embodiment, the dual slop integrator also integrates the reverse polarity of the voltage representing the current flowing through the voice coil and the reverse polarity of the voltage across the voice coil in order to cancel the inductance (L·di/dt) of the voice coil from the back EMF measurement.

The magnetic circuit includes a magnetically activated switch, a first set of flux conductors, and a second set of flux conductors. The first set of flux conductors has first flux conductor flanges adapted to conduct flux from ends of the magnet. The second set of flux conductors is slidingly positioned relative to the first set of flux conductors and is adapted to conduct flux from the first set of flux conductors to the magnetically activated switch. The first set of flux conductors are adapted to rotate clockwise or counter-clockwise and to tilt up or down. The first magnetic circuit is adapted to conduct flux to activate the magnetically activated switch only when the first flux conductor flanges are rotationally aligned with ends of the magnet and tilted to an operational position.
