Abstract
A magnetic disc apparatus has a ramp holding the magnetic head in a position apart from the magnetic disc and a filter case holding a filter in the state of being bent in such a manner that the filter surrounds the ramp together with the magnetic disc. The filter removes dust in airflow which flows in the magnetic disc apparatus accompanying the rotation of the magnetic disc.
