Oberlin had fabricated a cotton or silk thread, into which steel dust or short clippings of fine wire would be suspended. The benefit of magnetic tape contains unconditional storage, inexpensive, high data density, fast transfer rate, flexibility, and ease of use. This type of storage was first invented in 1928 for sound recording purposes. Answer: Good question. 7. In 1877 Oberlin Smith learned of the magnetic sound recording device (Phonograph) by Thomas Edison and decided to improve the Edison phonograph without initially getting away from a magnetic sound recording. While tape has largely been displaced as a primary and backup storage medium, it remains well-suited for archiving because of its high capacity, low cost and long durability.
