Data storage device dynamically reducing coast velocity during seek to reduce power consumption
摘要：
A data storage device is disclosed comprising a disk comprising a plurality of tracks, and an actuator configured to actuate a head over the disk. While seeking the head from a first track toward a second track, a velocity of the head over the disk is measured, and a deceleration distance and a deceleration time is generated based on the measured velocity. A coast velocity is generated based on the measured velocity, the deceleration distance, and the deceleration time, and a control signal applied to the actuator is adjusted based on the measured velocity and the coast velocity.
摘要（中）：

公开了一种数据存储装置，包括包括多个轨道的盘，以及致动器，其被配置为在盘上致动头部。 在从第一轨道朝向第二轨道寻求头部时，测量头部在盘上的速度，并且基于测量的速度产生减速距离和减速时间。 基于测量的速度，减速距离和减速时间产生滑行速度，并且基于测量的速度和惯性速度来调整施加到致动器的控制信号。
