Fly-height management in a hard disk drive (HDD) |
摘要 |
A hard disk drive (HDD) including a first resistive temperature detector (RTD) configured to detect a temperature generated by proximity of a slider and a media. The first RTD is proximate an air bearing surface (ABS) of the slider. The HDD also includes a second RTD configured to detect at least one temperature correlated to a fly-height of the slider. The second RTD is not required to be proximate the ABS of the slider. HDD also includes a read/write integrated circuit (IC) configured to determine the fly-height of the slider based on detection of temperatures by the first RTD and the second RTD. |
