The disc memory is much simpler to operate than the drum memory and it also eliminates tape storage disadvantages. The flexible disc revolves above a resistive plate which is connected to a motor drive and a valve controlling the air flow. This allows a stabilization of the disc up to several thousand rpm. Magnetic head gaps of 5 to 10 microns were used successfully allowing high density storage of information 5 to 10 impulses per mm. Various diameter discs were studied usually about 280 mm. Up to 10,000 channels were recorded with one set of heads. Mechanical and electrical diagrams are given for the basic design of the system. Also oscillogram test pulses and a physical picture of the system are shown. The binary logic of the system is described in relating the system to several neutron time of flight spectrometers. Author
