The Development of the Flexible-Disk Magnetic Recorder

A brief history of the development of the flexible-disk magnetic recorder is presented. Principles of the aeroelastic behavior of the disk and the results of a mathematical analysis of the equilibrium operating conditions are discussed. Experimental results are given which illustrate the effects of operating parameters on disk dynamics. These results indicate the design considerations necessary to produce a wide range of new storage devices. The characteristics of some of the newly developed models are presented.
