Standing spin wave mode frequencies and linewidths in partially disordered perpendicularly magnetized arrays of sub-micron Permalloy discs are measured using vector network analyzer ferromagnetic resonance. Fitted demagnetizing parameters decrease with increasing array disorder. Frequency separation between first and second radial modes is found to be higher than theoretical predictions for isolated discs. The relative frequencies between successive spin wave modes are unaffected by changes to the long-range array ordering. An increase in standing spin wave broadening at low applied magnetic fields that has a magnitude which is correlated to array disorder is observed. The fitted intrinsic damping parameter is found to increase with increasing array disorder.
