Operating system provides an interface between user & Hardware. The Operating System manages hard disk to provide the fast access time. Most often, it has been observed disk scheduling algorithms incorporate Seek time as the only factor for optimal criteria & ignore the second factor i.e. Rotational Delay in the existing algorithms. In this paper both the factors seek time &rotational delay to schedule the disk have been considered with Equi-importance. The uncertainty associated with rotational delay has also been taken in account. Keeping in mind, a Fuzzy Inference system has been designed to optimize the overall performance of disk drive on the basis of If-then rule. This paper is a combining effort of our previous work. Finally, we have presented comparative study with the Seek time & Disk access time for various scheduling algorithms in relative to our proposed algorithm with the Mamdani types Fuzzy Inference system.
