    • A disk drive system includes a base, a disk rotably attached to the base, and an actuator assembly movably attached to the base. The actuator assembly moves the transducer to selected areas of the disk where information reprexentative of data is to be written or read. The actuator assembly maintains the transducer in a transducing relationship with the disk. The actuator assembly also parks the transducer or unloads the transducer to a park position. A portion of the actuator assembly rides over a ramp to a park position. The ramp includes a mechanism for increasing the coefficient of friction on the surface of the ramp. The coefficient of friction on the surface of the ramp is increased to help retain the actuator in its parked position. This helps maintain the actuator assembly in a parked position in the event of shock loading from dropping a computer or a disk drive. This in turn helps prevent head crashes or failure of the disk drive and possible data loss.
    • 磁盘驱动器系统包括基座,可旋转地附接到基座的盘,以及可移动地附接到基座的致动器组件。 致动器组件将换能器移动到盘的选择区域,其中要写入或读取代表数据的信息。 致动器组件将换能器保持与盘的换能关系。 执行机构组件也停放换能器或将换能器卸载到停放位置。 致动器组件的一部分在斜坡上行驶到停放位置。 斜坡包括用于增加斜坡表面上的摩擦系数的机构。 斜坡表面上的摩擦系数增加以帮助将致动器保持在其停放位置。 这有助于在从计算机或磁盘驱动器掉落的冲击加载中将执行器组件保持在停放位置。 这反过来有助于防止磁盘驱动器头部崩溃或故障以及可能的数据丢失。
