In electro-mechanical devices such as tape or video recorders, moment coming from the engine needed to overcome the motion resistance of the magnetic tape is of the same order of magnitude as the frictional resistance (of the rotating elements) not only in bearings but mainly in the surrounding medium which is air. The author of this paper did not find any materials on the motion resistance of rotating superficial elements in the surrounding gaseous medium. He therefore built the relevant measuring equipment and made a lot of experiments which allowed him to draw interesting conclusions and make some observations. The results of selected measurements of the resistance moment M(op) of the rotational motion of superficial constructional/elements have been drawn in the form of graphs of Mop = f(n) fiunction, where n is the rotational speed of the selected element of disk in revolutions per minute (rpm).
