Detailed explanation-1: -It was the first tape storage device for a commercial computer, and the relative low cost, portability and unlimited offline capacity of magnetic tape made it very popular. UNIVAC tapes were ½” wide, 0.0015” thick, up to 1, 500’ long, and made of phosphor-bronze with a metallic coating.
Detailed explanation-2: -Magnetic tape was first used for data storage in 1951. The tape device was called UNISERVO and was the main I/O device on the UNIVAC I computer.
Detailed explanation-3: -Magnetic Storage Media The first magnetic storage mechanism was the Telegraphone invented in 1898 by Danish scientist Valdemar Poulsen.
Detailed explanation-4: -In 1934, Allgemeine Elektricitäts-Gesellschaft (AEG), the German division of General Electric, began manufacturing a tape recorder called the Magnetophon, which used plastic tape coated with magnetic particles and was manufactured by BASF.
Detailed explanation-5: -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.
