摘要
首先对单头磁盘系统的电梯策略进行简要分析，然后根据双头磁盘系统的特点给出相应的电梯调度算法。在介绍模拟方法后，对先来先服务策略和电梯策略分别进行模拟，根据实验对两者作比较与分析，最后分析了电梯策略性能如何受两磁头之间距离ｄ的影响。
After analyzing the elevator strategy of the disk scheduling for the single head disk system, this paper explains an elevator scheduling for two-headed disk system. According to the simulation experiments, this paper illustrates how the performance of the elevator scheduling is influenced by the distance between two read/write heads.
