magnetic disk

A magnetic disk is a storage device that holds digital data using tiny magnetic regions on its surface. Think of it like a very advanced version of a vinyl record, where information is recorded in magnetic patterns that can be read and written by a computer. These disks are commonly found in hard drives, providing large storage capacity for files, programs, and operating systems. The disk spins quickly while a read/write head moves over its surface to access or save data. Magnetic disks are reliable, cost-effective, and essential for storing vast amounts of information in many electronic devices.
