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.

Base for data storage device with parallelism mounting features

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.

High magnetic reluctance motor assembly

An enclosure system includes a motor assembly that has a motor magnet and at least one motor coil. The enclosure system also includes a base coupled to the motor assembly. The base includes a first portion that includes a non-magnetic material and a second portion that includes a magnetic material. The first portion of the base is in closer proximity to the motor magnet than the second portion of the base.

A formed in place damper for a data storage device. The damper is formed of an elastomeric bead which is cured to a cover or component to form a damper body having contoured shape or surface formed by an outer surface of the cured elastomeric bead. The damper is formed in place to a cover of the data storage device so that when the cover is assembled to a base, the damper is interposed between the cover or housing and a disc spindle assembly, actuator or voice coil motor. Alternatively the damper is formed to drive components, such as the disc spindle assembly, actuator or voice coil motor.

The invention includes techniques for mounting a printed circuit board (PCB) on a housing for an electronic device. The housing includes a top cover that combines with a base to form an internal space within the housing. The PCB has at least one tab that extends from it and fits within a recess formed by the base to secure the PCB on a side of the base opposite to the internal space. The electronic device may additionally include a shield such that the PCB fits between the shield and the base and the shield assists in securing the PCB to the base. The housing may also include a locking mechanism to constrain the PCB tab to the base. Embodiments of the invention allow for a PCB to be mounted to an electronic device housing without the use of screws.

Electronic device housing

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.

In general, the invention is directed to techniques for forming a seal between parts of an overmold component. The overmold component includes a first part forming one or more thorough-holes and a second part overmolded to the first part. A through-hole may be, for example, a screw hole or an overmold material entrance hole. The through-holes formed by the first part are surrounded by an adhesive prior to overmolding the second part. After overmolding, the adhesive locally bonds the surface of the first part to the overmold part to make a seal around the through holes. For example, the overmold component may combine with a cover to form a housing of a disc drive or other electronic device defining an internal environment. In this example, the adhesive prevents external contaminants from entering the internal environment via the through-holes.
