When was the patent granted on the Audio Tape Recording?
Valdemar Poulsen was granted a German patent for first magnetic recording device. In 1898 he patented the telegraphone, the first successful magnetic recording device - USF patent 661,619. Fritz Pfleumer was granted a patent for applying magnetic powder to film or paper strips in 1928.

What is Audio Tape Recording?
A tape recorder is an audio storage device that records and plays back sound using magnetic tape. It records a shifting signal by moving the tape across a tape head that differentiates the magnetic domains in the tape in proportion to the audio signal.
In the computer world, recording is used on floppy disks, hard disks and magnetic tape as the main method for data storage.
The tape recorders are very simple indeed. The basic idea encompasses an electromagnet that applies a magnetic flux to the oxide on the tape.
A tape recorder's record head is a very tiny, circular electromagnet with a small gap in it.
The electromagnet consists of an iron core wrapped with wire and while recording, the audio signal is sent through the coil of wire to create a magnetic field in the core.
At the gap, magnetic flux creates a fringe pattern to fill the gap, and this is the flux what magnetizes the oxide on the tape.
Throughout playback, the motion of the tape pulls a fluctuating magnetic field across the gap. This creates a varying magnetic field in the core and therefore a signal in the coil and the signal are amplified to drive the speakers.
