Abstract
A method for predicting and mitigating recording head failure in a data storage device. Thermal condition parameters of recording heads are monitored during operation. The thermal condition parameters are analyzed to identify conditions indicating a likelihood of failure of the recording heads. The analysis is performed by a simple model that compares the thermal condition parameters to predefined thresholds, or a machine learning model trained to predict time-to-failure of the recording heads based on the thermal condition parameters. Corrective actions are implemented to mitigate the likelihood of failure and extend the operational lifetime of the recording heads.
