摘要： A removable disk clamp assembly for mounting disk media on a motor-driven spindle of a magnetic read-write device includes a disk clamp and a mechanism for generating a predetermined force to press the disk media to a flange of the spindle such that the predetermined force can be repeatedly overcome by an applied counterforce to remove the disk clamp from engagement with a hub of the spindle. Such a mechanism may include a spring-loaded removable disk clamp assembly or a magnetic removable disk clamp assembly, and whereby a vacuum-driven chuck may be employed for disk and clamp handling purposes, all of which are suitable for implementation and use in a read-write device configured for use in an archival data storage system library such as in a cleanroom storage system.

摘要： Provided is a spindle motor having an electrostatic discharge (ESD) path that can stably discharge electric charges introduced from the outside to a rotating shaft through a base plate, in a structure of forming a bearing housing by using a resin and insert-molding the base plate. The spindle motor includes: a rotor to the central portion of which one end of a rotating shaft is coupled; a bearing that rotatably supports the rotating shaft; a bearing housing that accommodates the bearing in the inside of a groove and that is made of a resin; and a base plate whose inner circumferential portion is buried and combined in the inside of the bearing housing, wherein part of the base plate is in contact with the bearing to thus discharge externally introduced static electricity through the rotating shaft, bearing, and the base plate.

摘要： A spindle motor includes a flat stator, a rotor magnet arranged above the stator, and a magnetic portion made of a ferromagnetic material. The magnetic portion is positioned lower than the stator and the magnetic portion are axially overlapped with coils. A magnetic attraction force is generated between the magnetic portion and the rotor magnet. Since the magnetic portion is positioned lower than the stator, it is possible to cause magnetic fluxes to efficiently flow between the rotor magnet and the stator. Further, the stator includes a protrusion protruded radially outward beyond an outer circumferential portion of a rotor hub. Accordingly, in a plan view, the stator is positioned radially outward of the rotor hub.

摘要： The disk clamp apparatus and a spindle motor having the same according to the present invention has an industrial applicability in that a radial force of a claw on a disk is greater than a radial force of an arm to the disk to prevent the radial force of the arm applying to the disk from affecting the disk, whereby matched center of the clamp body with a center of the disk by the law is not affected by an arm, such that the center of the disk comes to have a relatively smaller deviation from the center and to thereby enhance the reliability of the product.
