What is a Tape Recorder?
A tape recorder is a device that uses electromagnets to record and play back sound. Once the sound is recorded, it can then be reproduced using the player component that almost any tape recorder will have. It was the dominant audio technology during the last several decades of the 20th century. A tape recorder works by running a tape coated with a type of iron oxide over the electromagnetic head of the machine. Depending on what its function is at that particular time, new information can be put on the magnetic tape or it can be read back. Due to the use of magnets, the audio cassette is highly susceptible to magnetic fields and therefore needs to be kept away from all magnets. This is one of the easiest ways to damage a recording. The tape recorder was the precedent of the video recorder, which is still in widespread use today. The basic technology between the two is very similar. The cassette used in a tape recorder can be the standard size, or one much smaller, which is known as the
