DATA PROCESSINGMAGNETIC DRUMS, AVIONICSA method is described for developing a consistent framework for comparing the request handling capabilities of various drum memories. The method permits one to estimate the request capacity of a drum, given its physical characteristics together with a number of assumptions regarding such factors as data organization, blocking average quantity of data transferred per request, and effective latency time. The method developed is used to compare the capability of several existing or proposed airborne drums. The effect of a number of possible modifications to a particular drum e.g., increase density, increased rotational speed, reduction of number of overhead bits is also examined.
