Abstract

Eugene A. Igel says that the axis of a rotating mirror of finite thickness is not located at the reflective surface, a condition not easily obtained, a noncircular cylindrical focal surface is generated. This nonideal condition allows either a perfect focous or a constant writing speed, but not both simultaneously. So do A. C. _ H. Edels and D. Whittacher, 3 resectively. Nevertheless, from the recent study it can be found out and theoretically demonstrated that the curve with constant writing speed and without out of focus can simultaneously be brought into being, and applied to some of high speed recording systems with cathoderay tube or that with leser leam.
