Each track had its own read/write head. Magnetic drums were used in the 1950s and 1960s. THIS DEFINITION IS FOR PERSONAL USE ONLY. All other reproduction requires permission.

At this point in time, discrete logic was the rule, and magnetic core memory still fairly new and rather expensive. This is where the rotating drum comes in, which is somewhat like a cross between ...

NASA's THEMIS mission proves a 45-year-old theory that the outer boundary of Earth's magnetic field vibrates like a drum. Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of ...

And (drum roll) this is the first time since researchers ... on Earth and Beyond] The dayside magnetosphere, the side of the magnetic field directly between the Earth and the sun, is a vast ...
