Abstract
An optical disc or other data storage medium has a substrate supporting a data storage region for storing readable data, and is caused to spin or is otherwise subjected to motion when read. A reservoir attached to the substrate and located in proximity to the data storage region stores a liquid reagent by liquid surface phenomena. When the medium is moved in order to read it, the centrifugal or other force causes the reagent to flow from the reservoir to interact with the data storage medium and interfere with the readability of the data.
