摘要： A disk drive and a method for operating the disk drive compensates for rotational vibration (RV) by adaptively modifying the gains of two separate linear vibration sensors so the sensor gains are optimal under any given condition. The two sensors provide two signals S1, S2, respectively, to the disk drive's servo control processor that generates the control signal to the voice coil motor (VCM) actuator that controls the positioning of the read/write head. The processor uses S1, S2 and the head position error signal (PES) as inputs to run an adaptive RV feedforward (RVFF) algorithm. The adaptive RVFF algorithm takes the PES and sensor outputs S1 and S2 as inputs, mathematically determines the required correction to the sensor gain factors k1 and k2, respectively, and then adjusts the gain factors k1 and k2 accordingly. Each signal S1, S2 is then modified by its adjusted gain factor k1, k2, respectively. The difference in the modified S1, S2 signals is the RVFF signal that is summed with the control signal to generate the RV-compensated control signal to the VCM actuator.

摘要翻译： 磁盘驱动器和用于操作磁盘驱动器的方法通过自适应地修改两个单独的线性振动传感器的增益来补偿旋转振动（RV），使得传感器增益在任何给定条件下是最佳的。 两个传感器分别向磁盘驱动器的伺服控制处理器提供两个信号S1，S2，该伺服控制处理器产生对控制读/写头定位的音圈电机（VCM）致动器的控制信号。 处理器使用S1，S2和头位置误差信号（PES）作为输入来运行自适应RV前馈（RVFF）算法。 自适应RVFF算法将PES和传感器输出S1和S2作为输入，分别数学地确定传感器增益因子k1和k2所需的校正，然后相应地调整增益因子k1和k2。 然后，通过其调整的增益因子k1，k2来修改每个信号S1，S2。 修改后的S1，S2信号的差异是将RVFF信号与控制信号相加，以产生向VCM致动器的RV补偿的控制信号。

摘要： A hard disk drive has a flexible cable and a flexible cable damper positioned adjacent to but separate from the flexible cable. The damper is a thin film loop with a damper patch that is completely independent of the flexible cable. The damper strip is a non-signal carrying substrate and has the constraint layer attached to it opposite the flexible cable. Both the damper and flexible cable extend in an arcuate configuration from the base to an integrated lead suspension tail extending from the actuator.

摘要： A dual-stage actuator disk drive has both a rotary primary actuator and a rotary secondary actuator. When the primary actuator initiates a seek there are two torque components acting on the center of mass of the secondary actuator's moving portion. The center of rotation of the moving portion is located at an optimal location relative to the center of mass of the moving portion, which results in cancellation of the two torque components and a secondary actuator that has essentially no resonant frequency in response to a seek by the primary actuator. If the optimal location can not be achieved because of assembly tolerances, then the center of rotation is placed at a distance at least as great as the assembly tolerance from the optimal location.

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.
