Patent number: 6856489Abstract: Windage proximate to a spinning disk within a disk drive is directed through a plurality of apertures in a ramp situated near the outside diameter of the disk. A tab extending from a load beam that supports a slider rests on the ramp when the drive is not in use. When the drive is started the disk begins to spin and an actuator moves the load beam to bring the slider over the surface of the disk. As the load beam moves, the tab is guided along the ramp and cushioned by the air flow emerging from apertures in the ramp beneath it. When the drive is stopped the actuator brings the load beam back so that the tab engages the ramp. A cushion of air is again provided as the tab is moved along the ramp as the tab is returned to a parked position.Type: GrantFiled: January 27, 2004Date of Patent: February 15, 2005Assignee: Western Digital (Fremont), Inc.Inventors: Muhammad A. Hawwa, Jamshid Bozorgi, Aric Menon

Publication number: 20030089182Abstract: A polymer-based flexible structure with integrated sensing/actuator means is presented. Conventionally, silicon has been used as a piezo-resistive material due to its high gauge factor and thereby high sensitivity to strain changes in a sensor. By using the fact that e.g. an SU-8 based polymer is much softer than silicon and that e.g. a gold resistor is easily incorporated in SU-8 based polymer structure it has been demonstrated that a SU-8 based cantilever sensor is almost as sensitive to stress changes as the silicon piezo-resistive cantilever.Type: ApplicationFiled: September 6, 2002Publication date: May 15, 2003Inventors: Jacob Thaysen, Ole Hansen, Aric Menon, Anja Boisen

Patent number: 6515791Abstract: An active, optical, piezoelectric actuated modulator allows switching between a reflecting state and an anti-reflecting state. The modulator, or switch, is based on the precise controlling of an air gap between a thin film membrane and a substrate. The thin film membrane is deformed by a miniaturized adaptive material, such as electrostrictive or piezoelectric (PZT) material. Maximum optical reflection is realized when the air gap is equal to a multiple of a quarter wavelength of an impinging optical beam, while anti-reflection is achieved when the thickness of the air gap is equal to zero or is different from a multiple of the quarter wavelength of the optical beam.Type: GrantFiled: February 11, 2002Date of Patent: February 4, 2003Assignee: Read-Rite CorporationInventors: Muhammad A.
