    摘要： An aspect of the invention can be regarded as a disk drive that includes a disk drive base and a spindle motor hub rotatably coupled to the disk drive base. The disk drive further includes a first disk disposed about the spindle motor hub. The disk drive further includes a second disk disposed about the spindle motor hub. The disk drive further includes a first disk spacer disposed between and in mechanical communication with the first and second disks. The first disk spacer has a first disk spacer first side disposed adjacent the first disk and an opposing first disk spacer second side disposed adjacent the second disk. The first disk spacer first side is defined by a first disk spacer first surface pattern. The first disk spacer second side is defined by a first disk spacer second surface pattern different than the first disk spacer first surface pattern.

    摘要： A method for reducing data access time in a disk drive. The disk drive includes an actuator and a servo controller. The servo controller commands the actuator to perform a seek from a current position to a target position using a profile of command effort to the actuator. The profile comprises an acceleration profile and a deceleration profile. In one aspect, the method includes defining a read profile for a seek used to position the actuator to execute a read command. A write profile is defined for a seek used to position the actuator to execute a write command, the write profile being different from the read profile for a respective seek distance. The read and write seeks are performed using the read profile and the write profile. The average time required for performing a seek command is reduced as a result of the difference between the read profiles and the write profiles.

    摘要翻译： 一种减少磁盘驱动器中数据访问时间的方法。 磁盘驱动器包括致动器和伺服控制器。 伺服控制器命令执行机构使用执行机构的命令轮廓来执行从当前位置到目标位置的搜索。 轮廓包括加速度曲线和减速曲线。 在一个方面，所述方法包括为用于定位致动器以执行读取命令的搜索定义读取轮廓。 对于用于定位执行器以执行写入命令的搜索来定义写入配置文件，写入配置文件与相应寻找距离的读取配置文件不同。 读取和写入寻找使用读取的配置文件和写入配置文件执行。 作为读取配置文件和写入配置文件之间的差异的结果，执行查找命令所需的平均时间被减少。
