tape recorder

A tape recorder is a device that captures sound by recording it onto magnetic tape. When you speak into its microphone, the sound waves are converted into electrical signals, which then magnetize tiny particles on the tape. This process stores the audio data so you can listen to it later. To play back, the tape moves past a playback head that detects the magnetic signals and converts them back into sound. Tape recorders were widely used before digital technology, offering a reliable way to record music, voice, and other audio content with good quality and portability.
