IBM’s first magnetic storage unit, the IBM 726 (see below), was introduced on May 21, 1952 as a data successor to the punched card.
But, the use of magnetic tape for high-speed data storage would never have been possible without the invention of the vacuum column by James Weidenhammer and a team of six other engineers working at an IBM facility in Poughkeepsie, New York.
The inventors received a patent for the vacuum column, and it became the industry standard for many years.
And now, 63 years later, magnetic tape storage is still in wide use worldwide.
