| 20080247078 | Altitude sensing systems and methods for fly height adjustment - Altitude sensing systems and/or methods for fly height adjustment in disk drive devices are provided. In certain example embodiments, a PZT-type pressure and/or altitude sensor may be located on the side of the disk drive proximate to the disk edge. When the disk rotates, the air flow generated by the disk will deform the PZT element of the sensor. The PZT element will generate a voltage in response to this deformation. Calibrations may be performed to compensate for altitude changes (e.g. the air inside of the disk drive will become thin and the air resistance will be reduced at higher altitudes). Also, the output sensitivity of the PZT element may change with the altitude change. After the altitude is sensed by the PZT element in the sensor, the servo motor may use this signal to calculate and/or adjust the dynamic fly height (DFH) and/or fly height of the read/write head. | 10-09-2008 |
