Patent number: 7542243Abstract: The present invention provides a transducing device. The transducing device includes a transducing element having a read element and a write element. The transducing device further includes at least one heating element formed within the transducing device and spaced apart from the heating element a sufficient distance to keep the at least one heating element from influencing a temperature of the transducing element.Type: GrantFiled: February 18, 2005Date of Patent: June 2, 2009Assignee: Seagate Technology LLCInventors: Huazhou Lou, Zine-Eddine Boutaghou, Deborah S. Schnur

Patent number: 6958889Abstract: A slider is used for supporting a transducing head proximate a rotating disc. The slider includes a primary air bearing having a disc opposing face bounded by a leading edge and a first trailing edge. An air bearing surface is defined on the disc opposing face. The slider further includes a secondary air bearing having a disc opposing face bounded by a front edge and a second trailing edge. The air bearing surface is defined on the disc opposing face. The air bearing surface has a pad proximate the second trailing edge wherein the transducing head is located on the pad. An interface connects the secondary air bearing to the primary air bearing and the interface displaces the transducing head vertically with respect to the primary air bearing to maintain head media spacing (HMS) between the transducing head and the disc substantially constant as the slider flies above the disc.Type: GrantFiled: November 7, 2001Date of Patent: October 25, 2005Assignee: Seagate Technology LLCInventors: Deborah S. Schnur, Zine-Eddine Boutaghou, Anthony P. Sannino

Patent number: 6661611Abstract: A slider for supporting a transducing head proximate to a rotating disc. The slider has a slider body having a disc opposing face and a longitudinal axis. The disc opposing face is bounded by a leading edge, a trailing edge, and first and second side edges. An air bearing surface is defined on the disc opposing face with the air bearing surface having at least one pad located behind the leading edge. A cavity is positioned on the disc opposing face and the cavity is recessed from the air bearing surface at a cavity depth. At least a portion of the cavity precedes the pad. A funnel directs airflow within the cavity from the leading edge to the pad.Type: GrantFiled: August 16, 2001Date of Patent: December 9, 2003Assignee: Seagate Technology LLCInventors: Anthony P. Sannino, Mark A. Chapin, Michael D. Mundt, Scott E. Ryun, Ram M. Rao, Deborah S. Schnur

Patent number: 6624984Abstract: A slider having a slider body is provided for actively controlling a fly height of the slider relative to a data storage disc. A first plurality of beams are affixed to a back surface of the slider body. The beams are disassociated from one another and are constructed of deformable material. Each beam, in response to an applied electrical control signal is deformable in a first dimension parallel to the back surface of the slider body. Deformation of the first plurality of beams in response to an applied electrical control signal affects slider fly height by changing one of slider body crown and cross curvatures to a greater extent than along the other. In accordance with other embodiments, multiple layers of deformable beams are attached to a slider. In yet other embodiments, piezoelectric material layers having anisotropic properties are substituted for beam layers.Type: GrantFiled: March 14, 2001Date of Patent: September 23, 2003Assignee: Seagate Technology LLCInventors: Derek A. Lewis, Deborah S. Schnur, Markus E. Mangold, Zine-Eddine Boutaghou

Patent number: 6594113Abstract: A slider is used for supporting a transducing head proximate a rotating disc. The slider includes a slider body having a disc opposing face bounded by a leading edge, a trailing edge and first and second side edges. The slider body has a longitudinal axis. An air bearing surface is defined on the disc opposing face. A furrow is positioned on the disc opposing face for flushing contaminants towards the trailing edge of the slider body.Type: GrantFiled: October 18, 2001Date of Patent: July 15, 2003Assignee: Seagate Technology LLCInventors: Ram M. Rao, Scott E. Ryun, Anthony P. Sannino, Deborah S. Schnur

Patent number: 6560071Abstract: A disc head slider includes a slider body having a disc-opposing face with leading and trailing slider edges, a slider length measured between the leading and trailing slider edges, a bearing surface, a recessed area, an inlet and a convergent channel. The recessed area is recessed from the bearing surface. The inlet has a leading channel end, which is open to air flow from the leading slider edge, channel side walls and a trailing channel end. The convergent channel has a leading channel end, which is open to fluid flow from the inlet, channel side walls and a trailing channel end, which is closed to the fluid flow. The trailing channel end of the convergent channel is located along the slider length rearward of at least a portion of the recessed area and forward of at least a portion of the bearing surface.Type: GrantFiled: September 25, 2001Date of Patent: May 6, 2003Assignee: Seagate Technology LLCInventors: Mark A. Chapin, Michael D. Mundt, Anthony P. Sannino, Deborah S. Schnur, Scott E. Ryun, Zine-Eddine Boutaghou

Publication number: 20030081352Abstract: A slider having slider level fly height or dynamic control. The slider level fly height control includes a flow gate on a slider body interposed in a flow path along an air bearing surface of the slider body. The flow gate is operable to regulate flow along the air bearing surface to provide dynamic or fly height control for the slider.Type: ApplicationFiled: April 5, 2002Publication date: May 1, 2003Inventors: Ram M. Rao, Zine-Eddine Boutaghou, Deborah S. Schnur, Michael S. Bowers

Publication number: 20020191340Abstract: The present invention includes a head slider for a disk drive. The slider includes a slider body having leading and trailing slider edges and first and second side edges. The body further includes an air bearing surface configured to face a disk surface. A raised portion is portioned on the air bearing surface. A plurality of isolated cup-shaped features having openings facing the leading slider edge is positioned on the raised portion. Furthermore, the plurality of cup-shaped features extends substantially from the leader slider edge to the trailing slider edge.Type: ApplicationFiled: April 4, 2002Publication date: December 19, 2002Inventors: Mark A. Chapin, Michael D. Mundt, Gary E. Bement, Scott E. Ryun, Ram M. Rao, Anthony P. Sannino, Deborah S. Schnur
