magnetic recording
Magnetic recording is a method used to store data using magnetic materials. It works by aligning tiny magnetic particles on a medium, such as tape or a hard disk, to represent information. For example, in audio tapes, sound waves are converted into electrical signals, which then magnetically imprint onto the tape. When played back, the tape's magnetic patterns are read and converted back into sound. This technology enables the storage of not just audio, but also video and data files, making it a fundamental part of how we record and access information in digital devices today.
