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.

Patent number: 7130149Abstract: 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.Type: GrantFiled: October 21, 2002Date of Patent: October 31, 2006Assignee: Seagate Technology LLCInventors: Yiren Hong, ChoonKiat Lim, Pohlye Lim, James H.

Patent number: 7122922Abstract: 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.Type: GrantFiled: October 16, 2003Date of Patent: October 17, 2006Assignee: Seagate Technology LLCInventors: Mo Xu, Victor C.
