摘要：
This disclosure describes a data storage medium, such as an optical disk, that includes a visually recognizable sensing element that changes in appearance in response to exposure to an environmental condition. The sensing element may sense any of a wide variety of environmental conditions, such as exposure to ultraviolet (UV) radiation, ozone, moisture, other non-UV spectrums of light, corrosive gasses, or the like. The invention can promote data integrity by alerting a user of possible media degradation.
