A base has an outer periphery and mounts the rotating disc type magnetic disc and the carriage arm, and has a side wall with an inner wall surface having an opening for inserting the carriage arm. The inner wall surface of the side wall defines a shroud surrounding the outer periphery of the magnetic disc, except at the opening in the side wall where the shroud is projected inwardly so as to decrease an opening angle of the opening in the side wall. A gap between the outer periphery of the magnetic disc and the shroud is set in a range not less than 0.1 mm but not greater than 0.6 mm.

摘要： Embodiments of the invention provide a magnetic disk device capable of improving the shielding function for the magnetic head yet maintaining a form factor. In one embodiment, a magnetic disk device comprises a magnetic disk; a magnetic head for recording/reproducing information; a magnetic disk drive mechanism for moving magnetic head in the radial direction of the magnetic disk; a housing including a base and a cover having a nonmagnetic material; and a magnetic shielding member having a magnetic material. The housing has a cut-away portion corresponding to a range in which the magnetic head moves, and the magnetic shielding member is formed in a U-shape including an upper wall portion, a side wall portion and a bottom wall portion. The magnetic shielding member covers the range in which the magnetic head moves, and is disposed in the cut-away portion so as to form substantially the same surface as the surfaces of the upper wall, side wall and bottom wall of the housing.
