Abstract
A low airflow hard disk apparatus comprises a base, a cover member, a rotational portion disposed in a disk chamber, a hard disk held by and rotatable with the rotational portion, a first projection portion disposed on the lower surface of the cover member and facing toward the upper surface of the hard disk, and a second projection portion disposed on the upper surface of the base and facing toward the lower surface of the hard disk. The first and second projection portions, preferably radially extending fins, prevent an air flow from generating by the rotation of the hard disk.
