Description
The first mass storage devices used commercially in the UNIVAC computer were oxide-coated metallic tapes with two recortding density modes. As a buffered system, the tape could read forwards and backwards at speed comparable to more recent tape systems. Two hundred bits per inch was the linear density on each of seven tracks used simultaneously. Data was organized into 60-word blocks. Each word had twelve decomal digits, each of these having seven bits.
