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.

Slider with transducing and heating elements formed on trailing end thereof and sharing same thin film structure

An electrostatic actuator for adjusting a spacing. A first body has an electrically conducting surface, and a second body has a body surface separated by the spacing from the electrically conducting surface. A conductor layer and an actuator electrode are recessed in the second body, and an electrode face faces the electrically conducting surface across the spacing. The actuator electrode comprises a semi-insulating material with a combination of electrical resistivity and thickness which prevents shorting of the conductor layer to the electrical conducting surface through a dielectric breakdown in the spacing.

Electrostatic actuator with multilayer electrode stack

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.

Slider with a compliant transducer interface

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.

Funneled trench AAB increased contact stiffness and enhanced take-off performance

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.

Fly height control slider with crown and cross curve de-coupling

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.

Slider with furrows for flushing contaminants and lubricant

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.
