Abstract
The magnetic domains of a perpendicularly magnetized media under different conditions that include the observations of the thin-film magnetic layer and observations through the glass or plastic substrate on which the magnetic film was deposited were observed using polarized light microscopy. The image contrast was reduced with increasing numerical aperture (NA) of the objective lens. The magnetic image contrast deteriorated when the polarization is caused by the differences between reflectivity/transmisivity of the p- and s-components of the polarization. Image quality obtained through the glass substrate is better than the image obtained in the plastic substrate due to the presence of vertical birefringence in plastic substrates.
