Magnetic recording is a diverse field, mechanically complex and challenging in both hardware design and material science. At times, this technology can appear brittle, but it has been proven to be a reliable way to store data that survives decades. Today, magnetic recording is the pivotal technology in data storage, ranging from magnetic tape, to spinning disks, floppy disks and modern hard disk drives (HDD). But how do write heads work, and how is data physically laid down on magnetic media? What is Heat-assisted recording? What is magnetic flux? What technologies were used in the past and how did they change to what we use today? This Micropolis Handbooks publication is mainly written in the form of a technical terms glossary, serving as a quick-start guide to magnetic data storage. The text introduces readers to the intricate mechanical process of how bytes end up on magnetic media and what is required to read this data reliably back. Structured alphabetically, the book combines short paragraphs and longer insight articles into a volume that invites casual browsing or reading from cover to cover. Several concepts are visualized in black and white illustrations. A reference book and first primer on the fascinating world of physical data storage and information technology.
