The PastThe IBM RAMAC 305 (the world's first hard drive) was officially announced today (September 13, 1956). In 1952, in San Jose IBM opened a research lab managed by Rey Johnson, and one of its first assignments was to create a magnetic storage system that could hold 5MB of data.
Johnson's group coated platters with magnetic material and stacked them on top of each other. Data was fetched by a head that traveled up and down the stack of rotating platters.
