摘要： A device for implementing thermally assisted magnetic recording, using a TE mode laser diode, and method for using it, are described. This device is shaped internally so as to provide three-dimensional self-focusing of plasmon radiation, thereby improving the coupling efficiency between the optical wave-guide and the plasmon generator as a result of ensuring a large overlap between these two modes.

摘要： A side shield structure for a PMR write head is disclosed that narrows write width and minimizes adjacent track and far track erasure. The side shield structure on each side of the write pole has two sections. One section along the ABS and adjacent to the pole tip has a height (SSH1) defined by SSH1≦[(0.6×neck height)+0.08] microns. There is a non-magnetic gap layer between the first section and a second section that is formed adjacent to the flared sides of the main pole layer and serves to suction leakage flux from the flared portion and prevent unwanted flux from reaching the first side shield sections. A fabrication method is provided that includes electroplating the first side shield sections, depositing the non-magnetic gap layer, and then electroplating the second side shield sections. Subsequently, a main pole layer and a trailing shield are formed.

摘要： Improved writability and a substantial reduction in adjacent track erasure are achieved by incorporating a composite shield structure in a PMR writer. There is a trailing shield formed a certain distance above the top surface of a write pole, a leading shield formed a certain distance below the bottom surface of the write pole, and a partial side shield having a section formed on each side of the write pole. The partial side shield thickness is less than that of the write pole. Each partial side shield section has a side that is parallel to the nearest write pole side and a top surface that is offset from the write pole top surface by 0 to 0.15 microns. A plurality of magnetic connections between two or more shield elements is employed to ensure correct magnetic potential. The large write pole has a flare angle of 45 to 75 degrees.

摘要： Techniques are provided for establishing a Virtual Desktop Interface (VDI) connection at a virtual desktop thin client (VDTC) device, between a VDI client in the VDTC device and a VDI server in a hosted virtual desktop server (HVDS). A unified communications (UC) control connection is established between a UC protocol stack on the VDTC device and a primary call agent, where the UC control connection is configured to allow the UC protocol stack to register with the primary call agent, and to send or receive commands from the primary call agent that are based on signals from a UC control application running on the HVDS. A UC control backup application is started on the virtual desktop thin client device in a standby mode that is configured to switch to an active mode in response to a failure to establish or maintain the UC control connection, or a failure to establish or maintain the VDI connection. A user interface is launched on the virtual desktop thin client device that is configured to perform UC backup functions.

摘要： A PMR writer with a tapered main pole layer and tapered non-magnetic top-shaping layer is disclosed that minimizes trailing shield saturation. A second non-magnetic top shaping layer may be employed to reduce the effective TH size while the bulk of the trailing shield is thicker to allow a larger process window for back end processing. A sloped surface with one end at the ABS and a second end 0.05 to 0.3 microns from the ABS is formed at a 10 to 80 degree angle to the ABS and includes a sloped surface on the upper portion of the main pole layer and on the non-magnetic top shaping layer. An end is formed on the second non-magnetic top shaping layer at the second end of the sloped surface followed by forming a conformal write gap layer and then depositing the trailing shield on the write gap layer and along the ABS.

摘要： A TAMR (Thermal Assisted Magnetic Recording) write head uses the energy of optical-laser excited surface plasmons in a scalable planar plasmon generator to locally heat a magnetic recording medium and reduce its coercivity and magnetic anisotropy. The planar plasmon generator is formed as a multi-layered structure in which one planar layer supports a propagating surface plasmon mode that is excited by evanescent coupling to an optical mode in an adjacent waveguide. A peg, which can be a free-standing element or an integral projection from one of the layers, is positioned between the ABS end of the generator and the surface of the recording medium, confines and concentrates the near field of the plasmon mode immediately around and beneath it.
