Abstract :
The writing speed and tonal range properties of dark trace tubes are analyzed and figures of merit are outlined. Experimental results are presented. Writing speed of a dark trace tube varies linearly with the ratio of beam current to spot size. The information writing rate varies directly with the beam current and inversely with the square of the spot size. The tonal range of dark trace tubes varies directly with the ratio of maximum contrast to spot size.
