Patent number: 9484059Abstract: 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.Type: GrantFiled: April 12, 2013Date of Patent: November 1, 2016Assignee: Seagate Technology LLCInventors: PohLye Lim, PowMing Yap, ChunHong D. Jing, WeiRhen S. Hoon, Chris M. Woldemar, Paco Gregor Flores, Anthony Joseph Aiello
