The ERA ATLAS delivered into a customer's facility started the 1100 production series of commercial computers traceable to the UNISYS 2000 computers of today. Core memory, the forerunner of random access memory (RAM), gradually replaced drum memory as the primary memory, though magnetic drums continued to be used as secondary storage for a while. Such memory is often just called core memory, or, informally, core.. Drum Magnets and Drum Separators are self-cleaning and provide continuous removal of ferrous contaminants from a wide range of free-flowing bulk and granular materials in high-volume applications. Drums were widely used in the 1950s and into the 1960s as computer memory. 3,161,861 and as being the co-founder of Digital Equipment Corporation. It is possible that all or part of the IBM-650 could be used as an a.uxil­ iary memory for the SCC-650 operating through the SCC-6S0's. [LABenson] 1. It was the main working memory in most computers during the 1950s and 1960s.

There are twelve basic configuration styles, including top mount models. The ATLAS is a single-chamber design, with either 2", 2.5", or 3" chamber diameter, as required by the application. It was so common that these computers were often referred to as drum machines. An IBM-6S0 digital calculator, which utilizes a magnetic drum memory and vacuum tubes for active elements, is presently available for use as the above mentioned auxiliary memory. Magnetic-core memory was the predominant form of random-access computer memory for 20 years between about 1955 and 1975. The magnetic drum memory machines kept (stored) their programs when power was turned off, therefore did not have to be re-loaded time and again. Core memory uses toroids (rings) of a hard magnetic material (usually a semi-hard ferrite) as transformer cores, where each wire threaded through the core serves as a transformer winding. ATLAS magnetic level indicators are produced in a wide range of materials of construction, including exotic alloys and plastics. The magnetic drum used for computer memory was invented in 1932.

A direct-access, or random-access, storage device.A magnetic drum, also referred to as drum, is a metal cylinder coated with magnetic iron-oxide material on which data and programs can be stored.Magnetic drums were once used as a primary storage device but have since been implemented as auxiliary storage devices.
