“…Z. Dimitrijevic, R. Rangaswami and E. Y. Chang have presented Semipreemptible I/O, which divides disk I/O requests into small temporal units of disk commands to improve the preemptibility of disk access [4]. Cheng -Han Tsai, Tai -Yi Huang, Edward T. -H. Chu, Chun-Hang Wei and Yu -Che Tsai propose a novel real-time disk-scheduling algorithm called WRR -SCAN (Weighted-Round-Robin-SCAN) to provide quality guarantees for all in-service streams encoded at variable bit rates and bounded response times for aperiodic jobs [5]. Daniel L. Martens and Michael J. Katchabaw developed a new disk scheduling algorithm focuses on dynamic scheduling algorithm selection and tuning [6].…”

Management of disk scheduling is a very important aspect of operating system. Performance of the disk scheduling completely depends on how efficient is the scheduling algorithm to allocate services to the request in a better manner. Many algorithms (FIFO, SSTF, SCAN, C-SCAN, LOOK, etc.) are developed in the recent years in order to optimize the system disk I/O performance. By reducing the average seek time and transfer time, we can improve the performance of disk I/O operation. In our proposed algorithm, Optimize Disk Scheduling Algorithm (ODSA) is taking less average seek time and transfer time as compare to other disk scheduling algorithms (FIFO, SSTF, SCAN, C-SCAN, LOOK, etc.), which enhances the efficiency of the disk performance in a better manner.
