摘要
Apparatus and method for detecting and compensating for lubrication disturbance (lube disturb) events on a rotatable data recording medium. In some embodiments, a lube disturb event is detected responsive to displacement of a data transducer away from a first memory location on a rotating data recording medium during a write operation to write data thereto. The lube disturb event arises responsive to a transfer of accumulated contamination from a data transducer to a lubrication layer on the rotating data recording medium and a smearing of the transferred accumulated contamination along the first memory location. The write data are stored to a different, second memory location instead of to the first memory location responsive to the detected lube disturb event.
