ABSTRACT:
A magnetic disk drive using a magnetic disk covered with a film of liquid lubricant for obviating wear ascribable to the friction and contact of the magnetic disk with a magnetic head is disclosed. The circumferential edge of the disk and the side wall of a casing are spaced from each other by 0.01 mm or less. In addition, the distance between the surface of the disk and a wall facing it, e.g., between the surfaces of adjacent disks or between the surface of each disk and the inner surface of a top wall or that of a bottom wall forming the casing is selected to be 3.00 mm or less.
