jan 1, 1878 - Magnetic Recording
Description:
In 1878, American mechanical engineer Oberlin Smith conceived the idea of recording electrical signals produced by the telephone on a steel wire after an 1877 visit to the laboratory of Thomas A. Edison.He spent 10 months developing the concept of a reel-to-reel wire recording system, filed a "patent caveat", but never did file a formal patent, deciding in 1888 not to pursue his idea. However, he made it publicly available by publishing his thoughts concerning magnetic recording in "Electrical World".
Majority of us have only seen one but didn't know what it was.
