How Data is Stored in Disk Systems by Quentin Jones is a document available to read on EtoBox.
Data is stored on different computer storage media that form a storage hierarchy. Primary storage like main memory provides fast access but limited capacity, while secondary storage like hard disks and tertiary storage like tapes provide larger capacity but slower access speed. Data on hard disks is stored magnetically on circular platters divided into tracks and sectors. Flash drives store data in arrays of transistors called cells that use floating gates to maintain data when unpowered. Magnetic tapes are
