What is magnetic storage, and how does it work?
Magnetic storage is a type of non-volatile memory that stores data using magnetic fields. It works by aligning tiny magnetic particles, called dipoles, to represent binary data (0s and 1s). When a magnetic field is applied, the dipoles align either parallel or anti-parallel to the field, allowing data to be written, read, and erased. This technology is widely used in hard disk drives (HDDs), magnetic tape, and magnetic stripe cards.
The magnetic storage process involves a physical interaction between the magnetic material and the read/write head. The head floats above the magnetic material, detecting changes in the magnetic field as it moves over the surface. This allows the data to be read and written with high accuracy and speed. Understanding how magnetic storage works is essential to grasping the concept of its durability and the factors that affect it.
