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 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.
摘要翻译：支撑头部的致动器的运动模式在盘旋转期间/之后被监视。显示器的信号被配置为产生头部刚好在旋转之前的数字指示。数字指示可选地是单位指示器，其被直接用作是否继续启动操作的决定。
