What was the Noble Prize winning advance that saved the magnetic recording industry and led to
major advances in the personal music device industry?
Solution
In 1887, Heinrich Hertz discovered that electrodes illuminated with ultraviolet light create
electric sparks more easily. In 1905 Albert Einstein published a paper that explained
experimental data from the photoelectric effect as the result of light energy being carried in
discrete quantized packets. This discovery led to the quantum revolution. In 1914, Robert
Millikan's experiment confirmed Einstein's law on photoelectric effect. Einstein was awarded
the Nobel Prize in 1921 for "his discovery of the law of the photoelectric effect",and Millikan
was awarded the Nobel Prize in 1923 for "his work on the elementary charge of electricity and
on the photoelectric effect".
In magnetic tape recording, the sound waves vibrate the microphone diaphragm and are
converted into a varying electric current, which is then converted to a varying magnetic field by
an electromagnet, which makes a representation of the sound as magnetized areas on a plastic
tape with a magnetic coating on it. Analog sound reproduction is the reverse process, with a
bigger loudspeaker diaphragm causing changes to atmospheric pressure to form acoustic sound
waves. Electronically generated sound waves may also be recorded directly from devices such as
an electric guitar pickup or a synthesizer, without the use of acoustics in the recording process
other than the need for musicians to hear how well they are playing during recording sessions.
