DISK DRIVE DEVICE IN WHICH REDUCTION IN UNBALANCED AMOUNT CAN BE ADJUSTED
摘要：
A disk drive device includes: a hub on which a recording disk is to be mounted; a base member; a bearing unit configured to support the hub in a manner in which the hub can be relatively rotated with respect to the base member; an extended annular groove portion provided in part of the hub around the rotational axis of the hub; and a weight member that is installed in the extended annular groove portion to adjust a rotational balance when the recording disk is being rotated with the hub. The weight member has a fixing mechanism that is slidable, when installed, in the direction of the extended annular groove portion and that can substantially maintain a stopped state at a fixing position.
摘要（中）：

磁盘驱动器装置包括：记录盘安装在其上的集线器; 基地会员 轴承单元，其构造成以轮毂相对于基座相对旋转的方式支撑轮毂; 围绕轮毂的旋转轴线设置在毂的一部分的延伸的环形槽部分; 以及配重构件，其安装在延伸的环形槽部分中，以当记录盘与轮毂一起旋转时调节旋转平衡。 配重构件具有固定机构，当安装时，该固定机构能够沿着延伸的环形槽部的方向滑动，并且能够在固定位置上基本保持停止状态。
