They realized that the pattern of reversals matched perfectly the magnetic profile they had compiled of the sea floor. This discovery, together with data from a 1964 research vessel, transformed ...

The tape is coated with an oxide EMULSION, which when exposed to the variations of the magnetic field at the recording head of a TAPE RECORDER, is arranged in similar variations, each particle of the ...

The first electronic storage medium, magnetic tape is made of flexible plastic with one side coated with a ferromagnetic material. The data are recorded as binary digits (bits) in the form of ...
