Abstract: The invention is directed toward techniques for shielding a reflector of a data storage medium from ultra-violet (UV) and solar radiation. Reflectors comprise materials, such as silver, that may degrade and lose their reflective properties when exposed to UV light. In some cases, exposing the reflector to UV light may degrade a recording layer positioned adjacent the reflector in a recordable data storage medium. Degradation of the reflector and/or the recording layer can lead to significant data losses in the data storage medium. The techniques described herein position a blocking material adjacent the reflector in order to protect the reflector and data stored on the data storage medium from exposure to UV light. The blocking material may comprise UV absorbing properties in order to substantially eliminate transmission of UV light through the backside of a data storage medium.
