How is our voice recorded on a tape recorder?

Tapes are recorded by printing magnetic patterns of sound on a special plastic tape.

A tape recorder stores the sound of your voice on a thin, plastic tape that has been treated with a chemical so it can be magnetized.

Tape  Recorder

To make a tape recording of your voice, you speak into a microphone.

The microphone changes the sound waves into electrical signals that go into a part of the recorder called the recording head.

The ribbon-like tape moves through the recording head as it unwinds from one spool to another.

The electrical signals made by your voice turn the recording head into a magnetic which prints a kind of magnetic picture of the sounds on the tape.

When the tape is played, it is run past the recording heat again.  But this time, the magnetized tape magnetizes the recording head.

The recording hear changes the magnetism into  electricity, and a speaker turns the electricity  into sound waves just like those your voice made. – Dick Rogers
