摘要： A method for minimizing once per revolution (OPT) positional errors in a single disk servo track writer (STW) comprises clamping a disc in the servo track writer; spinning the disc at a predetermined speed; determining an average OPR positional error; and adjusting a reference position for writing servo tracks on the disc to include the average OPR positional error. The apparatus includes a distance measuring device positioned adjacent the disc in the STW. Another method for reducing the effects of OPR positional error in a disc drive comprises positioning a disc on a drive motor spindle in a disc drive during assembly of the drive; spinning the disc at a predetermined speed; determining the position of maximum peak to peak OPR position error, and then readjusting the position of the disc on the spindle to minimize the error. The apparatus for this method includes a controller, a distance sensor, and a positioner for nudging the disc to an optimum position on the disc drive spindle.

摘要： A method for minimizing once per revolution (OPR) positional errors in a single disk servo track writer (STW) comprises clamping a disc having an outer edge in the servo track writer; spinning the disc in the servo track writer at a predetermined speed; measuring distance from the disc edge to a predetermined point to determine peak to peak once per revolution positional error; determining an average once per revolution positional error from the peak to peak once per revolution positional error; and setting a reference position for writing servo tracks on the disc equal to a predetermined track reference plus the average once per revolution positional error. The servo track writer apparatus comprises a spindle motor for supporting and rotating a disc and a distance sensor such as an interferometer mounted a preset distance from the edge of the disc for measuring the once per revolution outer diameter positional error.

摘要： A data storage system comprised of a plurality of disc drives which each comprise a plurality of data storage discs rotated by a polyphase motor. Each disc drive has a servo system for radially positioning transducer heads proximate the disc surfaces and generating an index signal for a selected orientation of the discs. A reference signal generator in each disc drive produces a reference signal at each of a succession of time intervals equal to the desired period of rotation of the discs and the disc drives are interconnected to enable each disc drive to sense a reference signal generated by any other disc drive. Each disc drive includes a microcomputer that is periodically interrupted and, during the interrupt, transmits the reference signal generated by the disc drive to the other disc drives in the absence of reception of a reference signal from another disc drive prior to the interrupt to provide a common reference signal for all of the disc drives. The speed of the motor of each disc drive is controlled in relation to the time interval between generation of the index signal in the disc drive and generation of the common reference signal. Alternatively, each disk drive can be operated independently to control the motor speed in relation to the time between successive index signals.

摘要： A method for optimizing settle characteristics of a read/write head on a data track on a rotating disk of a hard disk drive following a seek to the data track wherein each data track is assigned to a selected on of a plurality of concentric zones defined on the surface of the disk. Seeks are performed by a servo system in relation to a compensated velocity demand profile that provides velocities the head is to have at selected distances from a destination track and is selected for each zone by adding a velocity increment specific to the zone to a stored velocity demand profile for movement of the head in one direction and subtracted from the stored velocity demand profile for movement in the opposite direction. The velocity increment is selected to cause oppositely directed movements of the head in each zone for a selected demand velocity taken from the stored velocity demand profile to occur at equal speeds when added to the selected demand velocity for movement in one direction and subtracted from the selected demand velocity for movement in the opposite direction. The servo AGC is adjusted for each zone to cause the average of actual velocities of head movement in opposite directions to be equal to the selected demand velocity.

摘要： A method for eliminating overshoot of a destination track by a servo head of a rotating disk data storage device during seeks wherein the seek is carried out in accordance with an adaptive velocity demand profile selected to undershoot the destination track by an amount sufficient to offset overshoot arising from an incapacity of the servo head to follow a velocity demand profile. Prior to performing the seek, the servo head is moved a distance about a null position on the disk at which the only force on the actuator on which the head is mounted arises from a constant current passed through the actuator and the time for the movement is measured and utilized to select the adaptive demand profile. Adaptive demand profiles are obtained by performing seeks while modifying a nominal profile to eliminate actuator current ringing at the end of the seek.

摘要： Bag toss game target assemblies that include a deck and a base unit. The deck includes at least one through-aperture dimensioned to allow a bag to pass entirely therethrough. The base unit has a bottom portion that is configured to rest on a generally horizontal surface and a top portion that is configured to support the deck during game play. In one preferred embodiment, the base unit further includes an open-top storage receptacle that is covered by the deck during game play, but can be accessed by moving the deck independent of the base unit. In another preferred embodiment, the deck from at least target assembly can be removed from its corresponding base unit, and the corresponding base unit can be nested beneath and partially within the base unit of another target assembly.
