Detailed explanation-2: -A magnetic disk is a storage device that uses a magnetization process to write, rewrite and access data. It is covered with a magnetic coating and stores data in the form of tracks, spots and sectors. Hard disks, zip disks and floppy disks are common examples of magnetic disks.
Detailed explanation-3: -computer memory Magnetic disks are coated with a magnetic material such as iron oxide. There are two types: hard disks made of rigid aluminum or glass, and removable diskettes made of flexible plastic. In 1956 the first magnetic hard drive (HD) was invented at…
Detailed explanation-4: -Detailed Solution. Magnetic disk is not a sequence storage device.
Detailed explanation-5: -A hard disk is a metal platter coated with magnetic oxide that can be magnetized to represent data. Hard disks come in a variety of sizes. Hard disk for mainframes and minicomputers may be as large as 14 inches in diameter. Several disks can be assembled into a disk pack.
