Answer:
Direct acess
Step-by-step explanation:
Magnetic disk a medium known as Direct access.
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.
"Sequential access must begin at the beginning and access each element in order, one after the other. Direct access allows the access of any element directly by locating it by its index number or address. Arrays allow direct access. Magnetic tape has only sequential access, but CDs had direct access.
A flat rotating disc covered on one or both sides with magnetisable material. The two main types are the hard disk and the floppy disk. Data is stored on either or both surfaces of discs in concentric rings called "tracks". Each track is divided into a whole number of "sectors".
In computer memory: Magnetic disk drives. 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…
