It is shown explicitly that the frequencies of small k, infinite-film spin waves follow guide curves, which are simply the dispersion relations for pure magnetostatic modes (exchange constant D = 0) with the internal field H sub i replaced by H sub i + Dk to the 2nd power. A previous result, that the magnetostatic-mode frequencies are independent of the pinning, apart from splitting at crossovers of the guide curves, is a special case of the general result. Two regions of linearity of omega exist as a function of the magnitude k sub f of the wave vector in the plane of the film, but have no practical consequences at present. 8 pp. Ref. (Author)
