The Magnetic Drum of Gustav Tauschek. First magnetic drum memory, a magnetic data storage device and an early form of computer memory, which plays an important role in the computer memory development (e.g. used in ABC computer) and was widely used in the 1950s and into the 1960s, was invented by the Austrian engineer Gustav
Before there were discs, magnetic drum memory was the stateoftheart storage device. In fact, earlier computers like the IBM 650 had no other memory device (no core memory, for example) other than its drum.
Drum memory from the BESK computer Drum memory was a magnetic data storage device invented by Gustav Tauschek in 1932 in Austria . It was widely used in the 1950s and into the 1960s as computer memory . For many early computers, drum memory formed the main working memory of the computer. It was so common that these computers were often referred to as drum

In 1948 British electrical engineer, physicist and computer scientist Andrew D. Booth of Birkbeck College, London, created a magnetic drum memory, two inches long and two inches wide, and capable of holding 10 bits per square inch.. Booth offered his magnetic memory units for sale in 1952.
Drum memory, an early form of computer memory, used the drum as a working part, with data loaded to the drum. The drum was a metal cylinder coated with a recordable ferromagnetic material. The drum also had a row of readwrite heads that wrote and then read the recorded data. Magnetic core memory
Atlas used magnetic drum memory, which stored information on the outside of a rotating cylinder coated with ferromagnetic material and circled by read/write heads in fixed positions. ERA successfully sold a commercial version of the Atlas, the ERA 1103.
Almost in parallel to tape drive development, magnetic drum memory was finding use as a data storage media. While working under a contract with IBM (The Tabulating Machine Company) in 1928 , Austrian engineer, Gustav Tauschek, who was selftaught , developed the first electromagnetic drum
Drum memory consisted of a long metal cylinder coated in magnetic material, with rows of readwrite heads situated on the axis of the drum. It was once used as a primary storage device and remained common in computing through the 50s and 60s, but is now used as an auxiliary storage device.
Drum memory was a magnetic data storage device invented by Gustav Tauschek in 1932 in Austria.  It was widely used in the 1950s and into the 1960s as computer memory. For many early computers, drum memory formed the main working memory of
Magnetic drum memory. Invented all the way back in 1932 (in Austria), it was widely used in the 1950s and 60s as the main working memory of computers. In the mid1950s, magnetic drum memory had a capacity of around 10 kB.

Macdonald, Concord, Mass, assignor to Electronics Corporation of America, Cambridge, Mass a corporation of Massachusetts Application Aprii 25, 1955, Serial No. 503,503 .
Magnetic drums, which had fixed read/write heads for each of many tracks on the outside surface of a rotating cylinder coated with a ferromagnetic material, were used for both main and auxiliary memory in the 1950s, although their data access was serial.
Magnetic Drum Memory (1947) While rotating the drum, an electromagnetic pulse which represented a bit value could be stored by changing the magnetic orientation of the ferromagnetic particle that the write head passed over at that very moment.
Magnetic DrumsThe Cold War was gathering steam in 1948. Eager to enhance Americas codebreaking capabilities, the U.S. Navy contracted with Engineering Research Associates (ERA) for a stored program computer. The result was Atlas, completed in 1950.Atlas used magnetic drum memory, which stores information on the outside of a rotating cylinder coated with magnetic
1932 Gustav Tauschek developed drum memory in 1932. 1942 John Atanasoff successfully tests the AtanasoffBerry Computer (ABC) which was the first computer to use regenerative capacitor drum memory. 1949 Jay Forrester and other researchers came up with the idea of using magneticcore memory in the
