摘要
In one embodiment, a disc has a substrate; a data layer on the substrate; an anomaly-feature in the data layer disc capable of generating a read anomaly having a predictable anomaly profile; and anomaly profile data recorded in the data layer for characterizing the anomaly-feature. A disc can be labeled by imposing an anomaly-feature in the data layer capable of generating a read anomaly having a predictable anomaly profile; and disposing anomaly profile data on the disc, wherein the anomaly profile data characterizes the anomaly-feature.
