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.

A base of a data storage system includes a motor assembly. The motor assembly s includes a rotor that extends through an aperture in the base. The aperture extends from an inner surface to an outer surface of the base. The motor assembly also includes a motor stator mounted on the outer surface of the base. The motor stator includes a plurality of stator teeth radially and symmetrically arranged about the aperture in the base which are configured to support stator wires.

The present invention is a motor housing. The motor housing includes a centrally located rotor. The motor housing includes a stator having a plurality of stator teeth and a plurality of stator slots radially and symmetrically arranged about the rotor. Each stator tooth is spaced apart from each other by one of the stator slots. The motor housing also includes at least one printed circuit component deposited in at least one stator slot.
摘要:
An apparatus and associated method for making a base for a data storage device. The base has a plurality of raised pads defining coplanar supporting surfaces. The surfaces are adapted for supportingly engaging intermittent portions of a component supported by the base so that the base clearingly disengages other portions of the component between the pads.

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:
Method and apparatus for protecting a data storage device from fluid-borne contaminants. The device includes a housing in which a rotatable disc is supported, the disc having a data recording surface and an outermost perimeter. A filter assembly includes a first filter adjacent to the data recording surface and a second filter disposed beyond the outermost perimeter of the disc. During disc rotation, fluidic currents are generated and impinge a leading edge guide surface of the first filter. A first portion of the currents passes into a gap between the first filter and the data recording surface. A second portion of the currents passes along the leading edge guide surface to the second filter. The first filter is preferably characterized as a chemical adsorbent filter which adsorbs vapor phase (gaseous) contaminants, and the second filter is preferably characterized as a pass-through recirculation filter which captures particulate contaminants.
