7 results about "Patterned media" patented technology

Patterned media (also known as bit-patterned media or BPM) is a potential future hard disk drive technology to record data in magnetic islands (one bit per island), as opposed to current hard disk drive technology where each bit is stored in 20-30 magnetic grains within a continuous magnetic film. The islands would be patterned from a precursor magnetic film using nanolithography. It is one of the proposed technologies to succeed perpendicular recording due to the greater storage densities it would enable. BPM was introduced by Toshiba in 2010.

Intelligent control device based on multi-spectral characteristics of programmable patterned electrodeposition

This invention discloses a multi-spectral intelligent control device based on programmable patterned electrodeposition, comprising at least two types of reversible metal electrodeposition units with different patterns, arranged in a pixelated array. Each reversible metal electrodeposition unit consists of an infrared high-transmittance substrate layer, a conductive thin film layer, a patterned dielectric layer, a metal ion electrolyte layer, and a counter electrode. The patterned dielectric layer has patterned grooves; when an electric field is applied, metal is deposited on the patterned grooves, thus presenting the corresponding pattern. This invention arranges the reversible metal electrodeposition units in a specific order to form a large-area pixelated array device. Each reversible metal electrodeposition unit is equivalent to a unit of an electromagnetic metasurface and can be independently controlled, realizing spatial programming and dynamic reconstruction of the target multi-spectral characteristics. This allows for real-time, dynamic, and reversible reconstruction of large-area macroscopic optical patterns, thermal radiation distributions, and microwave scattering fields.

Fabrication technique for wire grid polarizer

A proposed fabrication technique for a polarization-absorbing wire grid polarizer avoids the need to etch through the multilayer stack of materials to form the grid structure. Initial reflective metal and dielectric buffer layers are patterned and etched in a conventional manner to create the desired grid topology. A small-angle coating process is then used to complete the fabrication process by first coating the top surface of the patterned dielectric with a polarization-absorbing metal. A second coating process is used to cover the created metal coating with a dielectric cladding material. Maintaining a small angle of incidence between the coating source and the wire grid structure ensures that top portions of the grid are suitably covered to create the desired multilayer wire configuration.
