摘要:
An apparatus illustratively includes a return pole (RP) and a shield. The RP has a first RP magnetic layer, a second RP magnetic layer, and a RP non-magnetic layer. The RP non-magnetic layer separates and magnetically decouples the RP first and second magnetic layers. The shield has a first shield magnetic layer, a second shield magnetic layer, and a shield non-magnetic layer. The shield non-magnetic layer separates and magnetically decouples the shield first and second magnetic layers. A method illustratively includes generating magnetic flux and collecting the magnetic flux through an inner magnetic shell.

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.
摘要:
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.

摘要:
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.
