ABSTRACT:
A divided housing for supporting magnetic disk devices therein is described. The housing is separated into a shell which supports a magnetic disk pack and a magnetic head positioner, and a cover to close the opening of the shell. Spindles of the disk pack and the head positioner are respectively held at opposite ends by ball bearings. Supporting holes for supporting the bearings are formed in side walls of the shell facing each other with one boring process. The centers of the bearings are aligned precisely coaxial to each other. The place which separates the housing into the shell and the cover intersects the side walls almost parallel to the line connecting the center of both spindles, but away from those supporting bearings. The supporting holes are perfect circles, and the open edge of the shell has no cut-in portion or grooves. This increases mechanical stength of the shell, and assures a stable bolding of the spindles. Therefore, the reliability of the magnetic disk device is improved.
