Abstract :
The position control described has been designed to achieve an accuracy of plus or minus 1 part in 4000. The control is part of the positioning mechanism for the read-write heads in a random-access magnetic-drum memory; it can position the heads to any 1 of 200 track locations, on command, in less than 100 milliseconds.
