摘要： Secure data is written to a disk during manufacture in such a way that it can be read but not copied. Methods include writing triangular transitions or very slow transitions from positive magnetic to negative magnetic and then erasing the negative parts to yield a code that consists of positive read back amplitudes only. Or, high frequency transitions can be written during servo writing.

摘要： The invention is a hard-disk-drive (HDD) assembly that includes a flame having the exterior dimensions of a particular form-factor HDD, an HDD with a form-factor smaller than the frame, a pair of mount assemblies that support the HDD entirely within the larger form-factor frame, and an electrical cable located entirely within the frame and having one end connected to the HDD and the other end exposed to the frame exterior at the position determined by the specifications of the larger form-factor. The HDD assembly thus presents a smaller form-factor HDD as a fully plug-compatible alternative to a larger form-factor HDD. The mount assemblies have spring-like cantilever arms in contact with damping material to provide a highly-damped nonlinear spring system that provides mechanical-shock resistance for the HDD in a direction normal to the planes of the disks and high stiffness in a direction parallel to the planes of the disks.

It also has an outer edge that connects edges of outer sides of the first and second side edges with viewed from the radial direction, and extends along an arc whose center is the center of rotation. A first magnetic pole region is located within a moving area of the first side edge to act on the first side edge. A second magnetic pole region is located within a moving area of the second side edge to act on the second side edge. The polarity of the second magnetic pole region is opposite to the polarity of the first magnetic pole region.

摘要： A magnetic recording disk drive has three vibration sensors mounted to the disk drive base to provide feedforward vibration compensation signals. First and second spaced-apart sensors are aligned generally parallel to a radius from the disk rotational axis to a head position on the disk between the inside diameter position (hID) and outside diameter position (hOD) for detecting rotational vibration about the disk rotational axis and linear vibration in the cross-track direction. A third vibration sensor is aligned generally orthogonal to the primary axes of the first and second vibration sensors for detecting primarily linear vibrations in the along-the-track or track circumferential direction. The disk drive servo control processor calculates, from the signals from the three sensors, a rotational vibration feedforward signal, a radial linear vibration feedforward signal, and a circumferential linear vibration feedforward signal which are summed with the actuator control signal to compensate for the vibrations.

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，分别在传感器增益因子k1和k2上数学确定所需的校正，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。
