MR head thermal asperity cancellation |
摘要 |
A disc drive data recovery system for recovering data from a magnetic disc having asperities provided. Readback data follows a nominal readback path and a thermal asperity cancellation readback path. A thermal asperity detector detects a thermal asperity in the readback signal and responsively selects the readback signal which follows the thermal asperity cancellation readback path. |
