Abstract
The current invention is directed to a method and optical storage media reading device for restoring data stored along a data storage path of an optical storage media, the data being stored on the optical storage media and being at least in part unreadable by a conventional optical storage media reading device due to chemical or physical changes within a recording layer or a reflective layer of the optical storage media. The method and device includes detecting deformations of a shape of a groove and lands of the groove extending along the data storage path, the deformations having been generated by a laser beam during a recording process of the optical storage media, and determining the data to be restored from the detected deformations and lands.
