    • Embodiments of the present invention relate disk drives, and in particular to realizing a positioning accuracy equal to that of an actuator having the mountable maximum number of suspensions, in an actuator having the smaller number of suspensions than the mountable maximum number. An embodiment of a magnetic disk device includes an actuator having an arm to which a suspension for applying a predetermined load onto a slider with a magnetic head is attached, and an arm to which a plate is attached instead of having the suspension. The plate attached to the arm in place of the suspension has a partially small section with respect to a section perpendicular to an arm longitudinal direction (constricted part), and the constricted part is located between a plate leading end and an arm attachment part.
    • 本发明的实施例涉及在具有比可安装的最大数量少的悬架数量的致动器中的磁盘驱动器,特别是实现与具有可安装最大数量的悬架的致动器相同的定位精度。 磁盘装置的一个实施例包括一个致动器,该致动器具有一个臂,附接有用于将预定负载施加到具有磁头的滑块上的悬架,并且连接有安装板的臂而不是具有悬架。 代替悬架而安装在臂上的板相对于垂直于臂长度方向(收缩部分)的部分具有部分小的截面,并且收缩部分位于板前端和臂附接部分之间。
