A ‘Reel-to-Reel’ tape machine is a magnetic tape recording platform that used reels of tape before the invention of cassettes.

It uses two reels, one supply reel and one take-up reel. The reels spin, drawing the tape across the tape heads that can erase, record, and play back the recorded tape. The recording is possible by the use of magnetic flux that shapes the tiny metals on the tape head.
