ABSTRACT:
In a recording apparatus capable of reducing an airflow and disturbance of the air flow simultaneously, thereby reducing flutter vibration effectively, a cover includes first convex sections for reducing a size of a gap between a disk surface and a cover or between the disk surface arid a housing in an area outside of an area in which an arm traverses on a disk in comparison with the area in which the arm traverses, and a second convex section on a part of the first convex sections to further reduce the size of the gap, and the second convex section is provided in a range extending with a tan shape thereof in a reverse rotational direction of said disk from a position distant by 110-170° in the reverse rotational direction from a straight line connecting the rotational shaft of said disk and the rotational shaft of said arm.
