Research output: Contribution to journalConference Articlepeer-review


Data can be write and read in spinning disk format using various forms of tungsten oxide as the media. Using thin film modeling and examining reflection curves, contrast ratios can be improved by choosing a wavelength to read that provides the largest change in reflection from the yellow to blue state. The films give a strong contrast ratio in their purest form compared to other media known which makes them good candidate for optical memory media.
