摘　　要：硬盘动态机械特性对硬盘的性能有着重要的影响,对其进行精密而又高效的测量是硬盘生产所必须的。首先讨论了现有测量硬盘动态特性方法的优缺点,然后结合微硬盘的结构特点和生产要求,设计了一种测试微硬盘动态性能的方法和测试系统。该系统通过计算机与微硬盘通信,共同完成测试;它不受昂贵测试设备和苛刻测试环境的限制,具有多个微硬盘可并行测试的体系结构,满足实际生产线测试速度和测试精度要求。具体介绍了系统的工作原理,各个模块的设计与实现,并给出了测试结果。The dynamical characteristic has great impact on the performance of the hard disk drives. High efficient and precise measuring is necessary for the hard disk products. Merits and demerits of some measuring methods have been discussed firstly. Then combining with the characteristic of microdrive and its product requirements, a measuring system of the dynamical performance of microdrive has been developed, by the communication of computer and microdrive. The system measures the parameters of the dynamical characteristic by a PC communicating with the microdrive, without expensive equipments and rigorous test environment. The system design supports parallel measuring, and meets the requirements of measuring speed and accuracy in product line. The design and implement of the system and each module has been introduced in this paper, some results have been given either.
