A method and apparatus for providing magnetic wear debris collection for an air
bearing of a spindle motor in a hard disk drive is disclosed. A magnetic ring is
provided near one end of the journal bearing forming an air bearing. In addition,
the mating surface of the air bearing is paramagnetic or ferromagnetic material.
The magnetic ring, acting as a debris collector, collects debris from the air bearing
to prevent deterioration of the air journal bearing. The journal bearing includes
a mating surface. The mating surface may be of a paramagnetic or ferromagnetic
material. A thrust bearing is provided to axially support the hub. The thrust bearing
may be an oil bearing or an air bearing.
