Richard G. Drew invented double-sided tape while working for the 3M company.
Magnetic tape was invented for recording sound by Fritz Pfleumer in 1928 in Germany, based on the invention of magnetic wire recording by Oberlin Smith in 1888 and Valdemar Poulsen in 1898. Pfleumer's invention used a ferric oxide (Fe. 2O. 3) powder coating on a long strip of paper.
