With a total of 3 patents to his name, Jensen has developed innovative processes that enhance the performance and durability of data recording disks.
Latest Patents
One of Jensen's latest patents is a chemical strengthening process for disks used in disk drive data storage devices. This process involves a salt mixture that is subjected to sub-micron filtration to remove impurities. The glass disks are chemically strengthened through ion exchange in a bath of molten sodium nitrate and potassium nitrate. The preparation of this salt mixture begins with high-grade bulk salt, which is melted and filtered through a stainless steel filter, ensuring the removal of trace contaminants.
Another significant patent by Jensen focuses on pH adjustment of a melt for use in microetching glass substrates. This method involves adding a base to the strengthening melt to raise its pH, allowing for a desired degree of microetch on aluminosilicate glass disk substrates. The process not only strengthens the glass but also improves its performance and durability. To prevent excessive etching that could damage the substrate, an acid may be added if the pH exceeds a certain limit.
