发明名称 PSEUDO-REFLECTIVE READ INHIBITOR FOR OPTICAL STORAGE MEDIA
摘要 <p>Systems and methods are described for inhibiting the readability of an optical storage media (200) due to changes in a pseudo-reflective material (220) that composes the optical media (200) after the optical media (200) has been exposed to air for a predetermined time. An optical media (200) includes a data encoded element (220). At least a fraction of the data transforms from a substantially optically reflective state to a substantially optically non-reflective state as at least in part a function of time from an initializing event. The systems and methods provide advantages because of low cost, limited content lifetime, avoidance of rental returns and minimum changes to existing manufacturing processes.</p>
