  In this paper, we use SPARC's HSBs, and LSBs galaxies to verify two issues.
The first one is related to one claim of \citep{Donato} D09, namely: is the DM
surface density (DMsd) a constant universal quantity, equal to $\log{(\rm
\Sigma/M_\odot pc^{-2})}=2.15 \pm 0.2$, or does it depend on the baryon surface
density of the system? The second one, is based on a MOND prediction that for
HSBs the DMsd is constant, and equal to $\log{(\rm \Sigma/M_\odot
pc^{-2})}=2.14$, while for LSBs the surface density is not constant and takes
values that are smaller than for HSBs and D09 prediction \citep{Milgrom2009}.
We find that HSBs shows a constant DMsd vs magnitude as in D09, and a constant
DMsd vs $\Sigma_{\rm eff}$ as in MOND prediction, for HSBs with $\Sigma_{\rm
eff}>200 L_\odot/pc^2$, and $\Sigma_{\rm eff}>300 L_\odot/pc^2$. However, the
value of the DMsd is larger, $\Sigma \simeq 2.61$ (in the case of the
DMsd-magnitude with $\Sigma_{\rm eff}>300 L_\odot/pc^2$), and $\Sigma \simeq
2.54$ (in the case of the surface DMsd-surface brightness with $\Sigma_{\rm
eff}>200 L_\odot/pc^2$). This value slightly depends on the threshold to
determine wheter a galaxy is HSB. In the case of LSBs, for $\Sigma_{\rm
eff}<100 L_\odot/pc^2$, and $\Sigma_{\rm eff}<25 L_\odot/pc^2$, the surface
density vs magnitude, for lower magnitudes, is approximately equal to that
predicted by D09, but several galaxies, for magnitude $M>-17$, have smaller
values than those predicted by D09. The DMsd vs $\Sigma_{\rm eff}$ shows a
similar behavior in qualitative, but not quantitative, agreement with MOND
predictions. In summary, in the case of HSBs both D09 and MOND are in
qualitative, but not quantitative, agreement with the data. In the case of LSBs
D09 is mainly in disagreement with the data, and MOND only in qualitative
agreement with them.
