OPTICAL DISC DETERIORATION DETECTION METHOD

摘要

A method (300) of determining a deterioration parameter of an optical record carrier (10) based on an optical record carrier characteristics signal parameter value obtained from multiple readout parameters upon inserting the optical record carrier (10) into a drive (100) is disclosed which is useful for optical discs such as CD's, DVD's and BD's, gives an early indication of optical record carrier deterioration and extends the lifetime of the optical record carrier (10).
