Magnetic storage - GCSE Computer Science Definition

Magnetic storage is a type of data storage that uses magnets to save and read information. In this method, data is stored on a magnetic surface, like on a hard disk drive or a magnetic tape, by creating small, magnetised areas that represent binary data (0s and 1s). When you want to access or read the data, the drive reads these magnetised areas and converts them back into digital information. Magnetic storage is known for being able to hold a large amount of data and is often used in computers, recording studios, and for backup systems. It is an important part of computer systems that helps to keep all your files and programs safe.

AQA GCSE Computer Science requires students to describe how magnetic storage works, meaning you must understand the basic operating principles. In contrast, Edexcel and OCR GCSE Computer Science only require knowledge of the advantages and disadvantages of magnetic storage, not how it functions.
