    • An inertial latching mechanism of high reliability, which can be incorporated in a slim profile disk drive or the like information recorders. Describing practically, the mechanism includes freely revolvable inertia arm 6 which couples with actuator 3when head arm is in a shunt position or the vicinity, whereas the coupling is released when the actuator is in proximity with disk 1 or the neighborhood; a drive means for holding inertia arm 6 to a right posture by taking advantage of magnetic pulling force at the place where the inertia arm is released from the coupling with actuator 3. Furthermore, coil arm 9's restriction section 9b and inertia arm 6's contact section 6b are disposed opposed to each other for forming a revolution restriction means which restricts an anti-clockwise revolution of inertia arm 6, as viewed from the above, when coil arm 9's coupling section 9a and inertia arm 6's coupling section 6a are in uncoupled state. The above-configured inertial latching mechanism can be used in a magnetic disk drive, an optical disk drive, a magneto-optical disk drive and other disk information recorders.
    • 一种高可靠性的惯性锁定机构,其可以结合在细长型盘驱动器等信息记录器中。 实际上,该机构包括可自由旋转的惯性臂6,当头臂处于分流位置或附近时,其与致动器3耦合,而当致动器靠近盘1或附近时,联接器被释放; 通过利用从致动器3的联轴器释放惯性臂的位置处的磁力拉力,将惯性臂6保持在正确的姿势的驱动装置。此外,线圈臂9的限制部分9b和惯性臂6的接触部分6b 当线圈臂9的联接部分9a和惯性臂6的联接部分6a处于非耦合状态时,形成一个限制惯性臂6的逆时针旋转的旋转限制装置,如上所述。 上述配置的惯性闭锁机构可用于磁盘驱动器,光盘驱动器,磁光盘驱动器和其他盘信息记录器中。
