media FDD: Floppy disk drive. Magnetic storage device that uses a read/write head to read‚ record and erase data onto a floppy disk. Data is stored in binary fashion (0s and 1s). Standard data capacity for floppy disks is 1.44 megabytes (MB)‚ although capacities ranging from 360 kilobytes (KB) to 2.88 MB were available over the lifetime of the technology. Considered obsolete since the PC99 standards‚ although still available on legacy systems and some specialty machines. HDD: Hard disk drive. Basic

Disk scheduling is one of the main responsibilities of Operating System. OS manages hard disk to provide best access time. All major Disk scheduling algorithms incorporate seek time as the only factor for disk scheduling. The second factor rotational delay is ignored by the existing algorithms. This research paper considers both factors‚ Seek Time and Rotational Delay to schedule the disk. Files are the most obvious objects in the operating systems manipulate. Everything is typically stored in files:
