Her innovative work focuses on methods and materials that enhance the functionality and efficiency of optical media.
Latest Patents
One of her latest patents is titled "Thermal bulk erasure method for dye polymer optical media." This method involves achieving a bulk erasure of dye polymer optical storage media by placing it in a temperature-controlled environment. The temperature is increased at a prescribed rate to exceed the glass transition temperature of the retention layer, transforming it from a glass-like state to a viscoelastic state. This transformation allows the retention layer to conform to the expansion layer, resulting in an unrecorded media configuration. The controlled temperature and time period ensure that the media is erased in bulk, making it ready for reuse while avoiding thermal shock and polymer degradation.
Another notable patent is for "Erasable recording media," which discloses an optical storage medium with a substrate, expansion layer, retention layer, and a liquid reflective layer. This innovative design aims to improve the performance and reliability of optical storage solutions.
