摘要： A magnetic circuit structure in a disk unit which can be manufactured at low costs. The magnetic circuit includes a main yoke manufactured by stacking a plurality of rolled steel plates and connecting them together by caulking. The magnetic circuit further includes an inner magnet, an outer magnet, and a side yoke all of which are mounted on the main yoke. Both ends of the inner magnet abut against a pair of shoulders formed on the main yoke, and both ends of the outer magnet abut against a pair of shoulders formed on the main yoke. Vertical movement of the inner magnet is prevented by a pair of presser plates and fixed to the main yoke, and vertical movement of the outer magnet is also prevented by a pair of presser plates and fixed to the main yoke.

摘要： An apparatus for fixing a suspension to an actuator arm has a mounting portion. The mounting portion has a first hole for fixing the suspension and a second hole for injecting an adhesive. The second hole is substantially perpendicular to the first hole and communicates with the first hole. A spacer having a cylindrical projection having an outer diameter slightly smaller than the diameter of the first hole is spot-welded to a base end portion of the suspension. The cylindrical projection of the spacer fixed to the suspension is inserted into the first hole of the mounting portion of the actuator arm, and the adhesive is next injected through the second hole into the first hole, thereby fixing the suspension to the mounting portion of the actuator arm by means of the adhesive injected.

摘要： 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 plane 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 perface 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 holding of the spindles. Therefore, the reliability of the magnetic disk device is improved.

摘要： Disclosed is a method of manufacturing a spindle motor using a fluid bearing. The spindle motor includes a hub having a support member for supporting a disk storage medium and a magnet, a fixed member having a coil, for holding the hub rotatably, and a fluid bearing provided between the hub and the fixed member. In this method, the hub is secured to the fixed member through the fluid bearing. This method includes a step of grinding a support surface of the support member. In this grinding step, a grinding member is applied to a part of the support member, and other part of the support member is pressurized by a pressurizing member to prevent the hub from falling down due to the pressurization by the grinding member.
