摘要： An active control mechanism and method for stabilizing a servo-controlled actuator system such as an actuator system in a data recording disk drive by compensating the vibrational modes of the actuator's arm assembly. The control mechanism has a sensing arrangement which can include one or more individual sensors attached to the actuator at locations where they generate signals in phase with the vibrational modes, and especially with all the major vibrational modes, of the arm assembly. A control mechanism derives from the signals an adjustment signal consisting of three corrective terms--a stiffening correction, an active damping correction and an inertia reduction correction--and the adjustment signal is used in the feedback control loop to stabilize the actuator system.

摘要： A system and method for determining the velocity and/or position of a coil driven actuator arm without the aid of servo signals. A sample-hold unit is used to measure no-motion coil voltage in the voice motor coil while applying a predetermined coil current. Then, while the same magnitude (opposite direction) current is applied to move the actuator arm, the coil voltage is measured. The coil voltage is reduced by the measured no-motion coil voltage, producing a measurement of back-emf. The back-emf may be amplified by a predetermined factor to yield an estimation of velocity, and this amount may be integrated to provide a gauge of relative actuator arm position.

摘要： In a digital servo control system especially suitable for use in disk drives, a sample integrity tester is provided. Sample measurements, indicating the position of a disk drive's read/write head relative to tracks of information on a recording medium, are subject to error due to noise. The sample integrity tester 2410, 2420, 2430 effectively filters out noise-corrupted measurements and thus prevents clearly erroneous measurements from contaminating calculations performed within the servo controller's control loop. If a measured position signal falls outside a given window (indicating a possible spurious position value has been read), an observer's predicted value is used rather than the spurious value. Using the predicted value allows the loop to operate in a "freewheel" (open-loop) mode. A preferred implementation of the sample integrity tester involves a coarse window that is static, and a fine window that changes dynamically based on an effort signal.

摘要： A channel circuit that receives an analog disk readback signal of a data storage disk drive includes a comparator string and a data channel binary decoder that together comprise what is commonly referred to as a flash analog-to-digital (A/D) converter, which processes the data channel information of the readback signal. The servo information of the readback signal is provided to the comparator string of the data channel flash A/D converter, whose output then is provided to a servo burst binary decoder for decoding to produce the desired servo burst data. Thus, the servo information is digitized and decoded at the relatively high speed possible with a flash A/D converter, without requiring a comparator string in addition to what would otherwise be provided for the data channel application.
