Thin film write head with interlaced coil winding and method of fabrication
InactiveUS6466401B1Increase working frequencySeparationConstruction of head windingsHeads using thin filmsResistConductive materials
The preferred embodiment of the present invention provides a write head having an interlaced conductor coil winding and method of fabrication. The interlaced winding of the present invention may have alternating turns of a first and a second coil. In the preferred embodiment, the side walls of successive coil turns are separated by an ultra thin inorganic insulation which defines the distance between successive turns of the first and second coil. In one method of fabrication, a conductive seed layer is deposited on a generally planar insulative surface, a resist mask is formed on the seed layer, and a conductive material deposited on the exposed seed layer to form the turns of the first coil. The masked portions of the seed layer are removed, after resist mask removal, to electrically isolate the turns of the first coil. The inorganic insulation may be formed in a layer conformal with the first coil. The second coil is formed between the turns of the first coil. A seed layer and mask may be used to facilitate second coil deposition. Etching, or planarization, may be used to electrically isolate the turns of the second coil. A capping layer may be formed over any exposed conductor material to insulate the winding from an upper pole structure or other overlying structure. Embodiments of the present invention may have multiple layers of conductor winding having some conventional, or all interlaced coil structure.

Polarization analysis unit, calibration method and optimization therefor
InactiveUS20030067602A1Increase speedImprove accuracyPolarisation spectroscopyLight polarisation measurementTemporal discriminationPolarimetry
Measurements at multiple distinct polarization measurement states are taken to define the polarization state of an input, for example to calculate a Stokes vector. High accuracy and / or capability of frequent recalibration are needed, due to the sensitivity of measurement to retardation of the input signal. A multiple measurement technique takes a set of spatially and / or temporally distinct intensity measurements through distinct waveplates and polarizers. These can be optimized as to orientation and retardation using initial choices and also using tunable elements, especially controllable birefringence elements. A device matrix defines the response of the device at each of the measurement states. The matrix can be corrected using an iterative technique to revise the device matrix, potentially by automated recalibration. Two input signals (or preferably the same signal before and after a polarization transform) that are known to have a common polarization attribute or other attribute relationship are measured and the common attribute and / or attribute relationship is derived for each and compared. The device matrix is revised, for example by iterative correction or by random search of candidates to improve the accuracy of the device matrix. Optional tunable spectral and temporal discrimination provide additional functions.

One or both electrodes may include a pocket, and the adjacent flow cells lie parallel to the electrode and free of shadowing and field inhomogeneity around a full circumference of the electrode. Flow paths within the helical cells are defined by barrier seals, which may form a path-lengthening maze, while unfilled cell regions may disperse or collect flow within a cell and define pressure gradients promote directional flows. Impermeable barriers between membranes further prevent the feed and concentrate flows from mixing. In various embodiments, seals along or between portions of the flow path may define a multi-stage device, may define separate feed and / or concentrate flows for different stages, and / or may direct the feed and concentrate flows along preferred directions which may be co-current, counter-current or cross-current with respect to each other within the apparatus.

Magnetic core plasmon antenna with improved coupling efficiency
ActiveUS20120008229A1Efficient couplingReduce energy lossCombination recordingNanoopticsVariable thicknessMagnetic anisotropy
A TAMR (Thermal Assisted Magnetic Recording) write head uses the energy of optical-laser generated plasmons in a magnetic core plasmon antenna to locally heat a magnetic recording medium and reduce its coercivity and magnetic anisotropy. To enable the TAMR head to operate most effectively, the maximum gradient and value of the magnetic recording field should be at a point of the magnetic medium that is as close as possible to the point being heated. In addition, the coupling between the optical mode and the plasmon mode should be efficient so that maximum energy is transmitted to the medium. The present invention achieves both these objects by surrounding the magnetic core of a plasmon antenna by a variable thickness plasmon generating layer, whose thinnest and shortest portion is at the ABS end of the TAMR head and whose thickest and longest portion efficiently couples to the optical mode of a waveguide to produce a plasmon.
