  • Abnormal surface pattern detection for production line defect remediation
    Patent number: 11650167
    Abstract: A defect inspection system provides an image of a surface of a hard drive media to a machine learning model that is trained to identify predefined classifications of abnormal surface patterns on the hard drive media, each of the predefined classifications being associated in system memory with a severity indicator. The defect inspection model analyzes the image and generates and output indicating that the image includes a pattern consistent with a select classification of the predefined classifications of abnormal surface patterns. When the severity indicator for the select classification satisfies a failure condition, the defect inspection system automatically implements a corrective action.
