摘要： A base plate for a disc drive incorporates a printed circuit board and connector assembly into an integral composite base that is bonded together to form a single composite structure. This structure provides the strength, stiffness and rigidity necessary to permit a reduction in overall thickness of a miniature disc drive to that substantially required for a Type I compact flash form factor data storage device.

摘要： A motor assembly in which magnetic attraction between the magnets and the base of the motor is reduced by providing increased magnetic reluctance. This is achieved without the need to increase the overall height of the motor assembly, thus making the motor assembly particularly suitable for use in applications with tight space constraints and power consumption limitations.

摘要： Stator and base plate interface alignment is provided for a spindle motor, meeting design specifications such that motor performance is maintained. A portion of a surface of the stator is separated from the base plate. Accurate stator z-height, parallelism and concentricity are provided for use with a low profile disc drive memory system. In an aspect, laminations are formed about a stator and the bottom layer laminations are formed with a smaller diameter than the top layer lamination. The stator bottom layer laminations seat on a flat base plate machined surface, avoiding a base plate corner radius. Precise machining of a small corner interface of the base plate where a stator is typically seated and aligned with the base plate is made unnecessary. Component machining costs, wear and tear to machining systems, and machining process cycle times are reduced.

摘要： A base plate of a disc storage system including an interior and an exterior surface, an entrance hole passes between the two surfaces and a groove surrounds the entrance hole and reduces the passage of air along an interface between the exterior and the interior surfaces. The groove may be in the shape of a circle or other alternative shapes such as a rectangle, as considered within the plane of the interior surface. An overmold is molded to the base plate and fills the groove. The plate is generally made of a plastic. The groove is amenable to the stamping process as well.

摘要： A base plate for a spindle motor is provided defining a minimal axial gap with a relatively rotatable magnet. In an example, a surface of the base plate is positioned at 0.1 mm from an adjacent surface of a relatively rotatable magnet. The base plate is comprised of a composite material such that stiffness is improved and acoustic vibration is reduced, while maintaining low power consumption and a fast start-up time. A first material, being a nonmagnetic material is employed adjacent to a motor magnet, and a second material having a preferred stiffness is employed at a greater radial distance from the magnet than the radial distance between a stator and the magnet.
