摘要： Method and apparatus for moving a control object, such as a data transducing head in a data storage device, from an initial position to a destination position. A base generation term describes a normalized trajectory (acceleration, velocity, displacement) of the control object away from the initial position and toward the destination position. A control profile is determined in relation to the base generation term as well as in relation to an acceleration distance and an acceleration time, respectively characterized as a displacement distance and an elapsed time during which the control object is accelerated. The control object is then moved in relation to the control profile. The base generation term is preferably stored in a table which is accessed and scaled in relation to the displacement distance (seek length) for the control object.

摘要： A disk drive is disclosed comprising a head actuated over a disk, the disk comprising a plurality of servo tracks defined by a plurality of servo sectors. An estimated radial location of the head is generated in response to an actuator control signal. A Gray coded track ID is detected from reading a servo sector, and decoded into a detected track ID. A burst position error signal (PES) is generated from reading servo bursts in the servo sector, wherein the burst PES represents a detected fractional servo track offset of the head. When the detected track ID is corrupt, a corrected track ID is generated using the estimated radial location and the burst PES, and the actuator control signal is adjusted in response to the corrected track ID and the burst PES.
摘要翻译：公开了一种磁盘驱动器，其包括在盘上致动的磁头，磁盘包括由多个伺服扇区限定的多个伺服磁道。响应于致动器控制信号产生头部的估计的径向位置。通过读取伺服扇区来检测灰色编码轨道ID，并将其解码为检测到的轨迹ID。脉冲串位置误差信号（PES）是从伺服扇区的伺服脉冲串中产生的，其中脉冲串PES表示检测到的磁头的分数伺服磁道偏移。当检测到的磁道ID被破坏时，使用估计的径向位置和突发PES产生校正的磁道ID，并且响应于校正的磁道ID和突发PES调整致动器控制信号。

摘要： A motion pattern of an actuator supporting a head is monitored during/after a disc spin-up. The monitor's signal is configured to generate a digital indication of where the head was just before the spin-up. The digital indication is optionally a single-bit indicator that is used directly as a decision of whether to continue a start-up operation.
