ABSTRACT:
A disk drive includes a rotatable data storage disk and a vane positioned adjacent to the disk that receives airflow generated during rotation of the disk. A sensor is operably coupled to the vane and measures airflow force on the vane. Because of a known relationship between altitude and airflow force, the amount of airflow force on the vane is indicative of altitude of the disk drive. The sensor provides an output signal that is indicative of measured airflow force on the vane. The vane surface may be oriented substantially orthogonal to a plane of the disk or substantially parallel with a plane of the disk.
