Answer :
A Magnetic disk, made of mylar, is used for random-access processing of data in a computer.
A magnetic disk is a round, flat piece of mylar that is used to store data in a computer. The disk consists of a thin layer of magnetic material, typically iron oxide, that is coated with a thin layer of lubricant. The data is stored on the disk in the form of tiny magnetic particles.
Magnetic disks are used for random-access processing of data in a computer. The disk is divided into tracks, and each track is divided into sectors. The data is stored in the sectors, and the sectors are read by a magnetic head. The head is moved to the correct track by a servo mechanism, and the sectors are read in sequence.
Magnetic disks are used in a variety of applications, including hard disk drives, floppy disk drives, and optical disk drives.
