Publication number: 20110286131Abstract: An apparatus and associated method for directing windage involves a body defining an aperture. A fastener is operably disposed in the aperture and is selectively engageable with a fixed support member between a first mode permitting rotation of the body around the fastener longitudinal axis, and a second mode affixing the body in place to the support member at a desired rotational orientation. A shroud depends from the body and is sized at a distal end for an operable mating relationship adjacent an arcuate edge of a disc that is rotatable around a disc axis. The shroud distal end is operably disposed a first distance from the fastener longitudinal axis in a direction of a plane including the fastener longitudinal axis and the disc axis. A leading edge of the shroud, with respect to a direction of windage established by disc rotation, is disposed a second distance from the fastener longitudinal axis that is the same or less than the first distance from the fastener longitudinal axis.Type: ApplicationFiled: May 19, 2010Publication date: November 24, 2011Applicant: SEAGATE TECHNOLOGY LLCInventors: Swee How Alvin Teo, JuiJing Lim, YongJie Tang, Suwandi Chendekiawan, BoonSeng Ong, Niroot Jierapipatanakul, Xiong Liu

Patent number: 7417823Abstract: An apparatus and method for mounting a shock sensor to the printed circuit board (PCB) of a disc drive are provided. In particular, the present invention allows the shock sensor to be mounted at any location on the printed circuit board rather than being limited to placement adjacent a mounting screw. The present invention includes a clamping mechanism for rigidly clamping the PCB to the head disc assembly (HDA) so that any shock is properly transmitted from the HDA to the PCB and then to the shock sensor. In one exemplary embodiment, the PCB is clamped between a shield and the HDA. The shock sensor is then position near the point at which the PCB is clamped so that the point of clamping provides transmission of any shock in the Z-axis to the shock sensor. Shocks in the X-Y axis direction are transmitted via the normal mounting screws.Type: GrantFiled: March 7, 2005Date of Patent: August 26, 2008Assignee: Seagate Technology LLCInventors: BengSee Lim, WaiOnn Chee, PeiKoh Lee, Jimmy TzeMing Pang, BoonSeng Ong, Niroot Jierapipatanakul

Patent number: 7312949Abstract: A base deck for a data storage device is preferably formed from a stamped, or fine blanked metallic platform portion, which supports an over-mold portion. The over-mold portion is a combination of elastomeric components and rigid structural components. In addition to providing structurally rigid side walls for the base deck, the over-mold portion also provides additional structurally rigid components, and features difficult to obtain from the platform portion formation process, such as a ramp load/unload feature and alignment guides. Elastomeric components provided by the over-mold process include gaskets for the top cover, motor, and actuator of the data storage device as well as impact dissipation members. The impact dissipation members aid in dissipating impact forces encountered by the data storage device during manufacturing of the data storage device as well as during the operational life of the data storage device.Type: GrantFiled: October 22, 2003Date of Patent: December 25, 2007Assignee: Seagate Technology LLCInventors: WaiOnn Chee, Niroot Jierapipatanakul, Quock Ying Ng

Patent number: 7038887Abstract: An apparatus restricting motion of an actuator assembly to preclude damage to a read/write head or a disc of a disc drive, the apparatus includes a pole piece with a crash stop mounting aperture and an overmolded crash stop communicating with the crash stop mounting aperture. The overmolded crash stop includes a retention channel formed by a top retention portion, a bottom retention portion and a main body portion during a process of molding the overmolded crash stop to the pole piece. The main body portion conforms to the crash stop mounting aperture, thereby precluding motion of the overmolded crash stop relative to the pole piece in a lateral direction, while the top retention portion and the bottom retention portion constrain motion of the overmolded crash stop relative to the pole piece in the vertical direction.Type: GrantFiled: November 8, 2002Date of Patent: May 2, 2006Assignee: Seagate Technology LLCInventors: Tak Koon Ooi, YongJie Tang, Niroot Jierapipatanakul
