Summary
Mechanical diagram (in hard copy) of the Magnetic Disk Assembly of the computer CSIRAC.
The first auxiliary memory for CSIRAC was a drum. Auxiliary memory was always referred to as a drum even though the later version was actually a disc.
The disk itself has a diameter of 296 mm with a thickness of 16 mm. The assembly is 330 mm high, 106 mm wide at its top and 167mm at its base.
Mechanical drawings show the physical construction of a component. They were used to define what was required in the manufacture of CSIRAC's hardware.
