Detailed explanation-1: -The first publicly demonstrated (Paris Exposition of 1900) magnetic recorder was invented by Valdemar Poulsen in 1898. Poulsen’s device recorded a signal on a wire wrapped around a drum. In 1928, Fritz Pfleumer developed the first magnetic tape recorder.
Detailed explanation-2: -Magnetic tape is a medium for magnetic storage made of a thin, magnetizable coating on a long, narrow strip of plastic film. It was developed in Germany in 1928, based on the earlier magnetic wire recording from Denmark.
Detailed explanation-3: -Magnetic tape is one of the oldest technologies for electronic data storage. 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.
Detailed explanation-4: -Magnetic tape storage is considered one of the most reliable, inexpensive and high capacity forms of storage on the market. The plastic components it’s built with, and the way that the data is recorded, help to make it durable and secure for a long period of time.
