Method and apparatus for testing the reliability of a disk drive |
摘要 |
The present invention provides a method, apparatus and program product for testing the reliability of a disk drive. The head-to-disk clearance of a disk drive is measured at different slider airbearing conditions. The change in head-to-disk clearance between the slider airbearing conditions is calculated. If the calculated head-to-disk clearance change between airbearing conditions for each of the heads in the disk drive exceeds a predetermined threshold, the disk drive is verified as having passed the reliability test. Differences in slider airbearing conditions are generated by varying pressures and/or temperatures under which the drive is operated.
