Abstract: A magnetic writer comprises a write pole and a near field transducer. The write pole has a leading edge, a trailing edge and a notch at the leading edge of the write pole. The near field transducer produces near field radiation. The near field transducer positioned in front of or at least partially within the notch.

Abstract: A novel technique for incorporating rapid thermal annealing into media sputter fabrication has facilitated the production of flyable media samples. Discs are fabricated with standard processing techniques to control physical grain size and crystallite texture. A CrMn caplayer ranging in thickness between 0.5 and 5 nm is subsequently deposited to provide the Mn-diffusant necessary to achieve post-treatment exchange de-coupling. While still in-situ and before application of protective overcoats, the discs are exposed to temperatures between 200° C. and 350° C. compatible with most media production processes. A threefold increase in coercive force (peak reaching ˜3800 Oe) and 10 dB improvement in medium signal-to-noise ratio is observed for the optimized process.

Abstract: A magnetic head having an air bearing surface is used to reduce thermal pole tip protrusion and recession. The magnetic head includes a substrate and a data transducer positioned upon the substrate adjacent the air bearing surface. The data transducer is comprised of a plurality of metallic layers. A compensation structure is positioned adjacent to at least one of the plurality of metallic layers, is exposed at the air bearing surface or recessed at the ABS and extends substantially perpendicular from the air bearing surface. The compensation structure is formed of a material having a coefficient of thermal expansion less than a coefficient of thermal expansion of a material forming the substrate.

Abstract: An approach is provided for tracking a vehicle via a web interface. A graphical user interface (GUI) screen includes a map showing an icon representing position of the vehicle. A zoom area is established over the map according to a rubber-band mechanism utilized by a user.

Abstract: An interface is provided for managing a plurality of tracked objects, each tracked object associated with a corresponding telemetry device. A request is received from a web browser for at least one action to be performed by the telemetry device. A message including information indicating the at least one action is transmitted, to the corresponding telemetry device. The web browser is configured to display at least one geographical map indication of at least one location of each tracked object.

Abstract: The present invention provides a magnetic recording media incorporating Zn containing layers in close proximity to a magnetic layer to provide media having increased coercivity and lower noise. The Zn containing layer can be incorporated in a rotating, translating or stationary recording media to operate in conjunction with magnetic transducing heads for recording and reading of magnetic data, as well as other applications. The magnetic recording medium of the invention preferably includes a Co or Co alloy film magnetic layer, underlayer structures to promote epitaxial crystalline structure in the magnetic layer, and a Zn containing layer to promote isolation between the magnetic grains. The medium can further include seed layers, underlayers, intermediate layers, and overlayers. The process of manufacture includes promoting diffusion of Zn to the magnetic layer grain boundaries.
