Detailed explanation-1: -Hard-disk drives represent the most widely used form of magnetic storage in use today. A hard-disk drive consists of a rigid disc made with non-magnetic material, which is coated with a thin layer of magnetic material. Data is stored by magnetizing this thin film.
Detailed explanation-2: -Magnetic storage: Hard Disc Drive (HDD) Relatively cheap per unit of storage. Fast access and retrieval times compared to other storage devices. Can be easily damaged, will slow down and eventually break over time. Slower access than Solid State Drives.
Detailed explanation-3: -Magnetic storage media and devices store data in the form of tiny magnetised dots. These dots are created, read and erased using magnetic fields created by very tiny electromagnets.
Detailed explanation-4: -Magnetic storage or magnetic recording is the storage of data on a magnetized medium. Magnetic storage uses different patterns of magnetisation in a magnetizable material to store data and is a form of non-volatile memory. The information is accessed using one or more read/write heads.
