A first adaptive fly height measurement is performed between a read/write head and a recording medium during a stage of qualification testing of a magnetic disk drive. A second adaptive fly height measurement of the read/write head is performed during a subsequent stage of the qualification testing. In response to determining that a fly height decrease between the first and second adaptive fly height measurements is above a threshold value, a mitigation operation is performed to remove a contaminant from a media-facing surface of the read/write head.

Method and apparatus to detect and mitigate contamination between a read/write head and a recording medium

A method is provided for protecting a head element of a computer disk drive during rework operations by applying thioropolymeric protective coating or film to the head element after the disk drive has been opened. Application of the protective coating is preferably performed utilizing a solvent-mediated deposition process. Further aspects of the invention include the application of the protective coating to the head element prior to storage of the head element or prior to shipping the head element in order to facilitate rework of the head element or other components of the disassembled disk drive.
