Disk drives must provide faster access time in order to optimize speed of I/O operations. In multitasking system with many processes, disk performance can be improved by incorporating a scheduling algorithm for maintaining several pending requests in the disk queue. This paper describes development of a simulator which uses four disk scheduling algorithms (FCFS, SSTF, LOOK for both upward and downward direction, and C-LOOK) to measure their performance in terms of total head movement. Five different types of test samples, containing request tracks from 8 to 50, have been used to obtain simulation results. Developed simulator runs successfully
