Abstract: A fluid dynamic bearing motor and method are provided for use with various disc drive memory device products differently rated by operational rotational speed. The operational speeds are those speeds measured during reading and writing memory operations to the memory device. In an aspect, the present invention meets full operating requirements, including stiffness and power requirements, at multiple rated speeds for use with either standard or high-end performance disc drive products. Costs associated with a dedicated manufacturing line for high-end products are substantially reduced. A single manufacturing line can serve both standard and high-end disc drive memory device products. The present invention is especially useful in reducing costs of 2.5 inch notebook products that are typically marketed in two levels of performance, namely, 5400 RPM standard performance products and 7200 RPM high performance products.

Abstract: Method and apparatus for securing a disc stack to a spindle motor hub. In some embodiments, a disc clamp assembly includes a spring clamp with an annular contact portion which contactingly engages a disc stack and a central aperture through which a hub projection of the spindle motor hub extends. A plurality of interlocking semi-annular shim segments interlock together to form a continuous retention ring assembly which wedges between the spring clamp and a shoulder surface of the spindle motor hub.
