ABSTRACT:
A disk apparatus includes a rotatable disk having at least one recording surface, a head for reading or writing information from or to the rotatable disk, a head drive for moving the head across the recording surface of the rotatable disk within a head moving range, and an enclosure for housing therein the rotatable disk, the head and the head drive. A printed circuit board is mounted on the enclosure. A shielding member is attached to the outer surface of the enclosure and located in a space defined between the enclosure and the printed circuit board. The shielding member has a size substantially corresponding to the head moving range.
