A detailed study on the influence of the focusing lens numerical aperture on the InSb super resolved spot is presented. The super resolution effect is described using the threshold model, where the material permittivity locally changes under laser exposure, being rigorously simulated in a finite element method program. The superresolved InSb focused spot is investigated for a wide range focusing lenses systems, from high to low numerical apertures. An extension of the model to account for disc motion is discussed. Such dynamic super-resolution near-field structure (Super-RENS) threshold model is suitable for readout signal analysis when combined with a ``quasi-scalar'' readout program, also described. Interesting properties of the InSb Super-RENS focused spot, such as sub-diffraction limited spot size and the general conditions to achieve it, are shown. An analysis on the Super-RENS readout signal is also given, with useful applications in optical data storage. Thus, this work greatly helps in understanding the InSb scatterer type of Super-RENS effect for optical data storage and other super resolution applications.
