<p>A disc drive data recovery system (100) for recovering data from a magnetic disc (110) having asperities provided. Readback data (202) follows a nominal readback path (210) and a thermal asperity cancellation readback path (218). A thermal asperity detector (204) detects a thermal asperity in the readback signal and responsively selects the readback signal (214) which follows the thermal asperity cancellation readback path (218).</p> |
