摘要： Electromagnetic radiation from an optical source is directed onto a metallic structure. The metallic structure in turn emits optical output from an emission region in the structure and onto a recording medium (e.g., a magnetic recording disk), thereby heating the medium. The output from the emission region is enhanced due to surface plasmons in the metallic structure. The surface plasmons are generated by an array of features (such as ridges or trenches) in the metallic structure and act to increase the emitted optical output from the emission region beyond what the emitted optical output from the emission region would be in the absence of these features. The apparatus and associated method are useful for data recording, e.g., thermally assisted data recording.

摘要： A magnetic recording disk drive with patterned disk media, wherein discrete magnetic data blocks representative of the individual data bits are isolated from one another, uses the discrete data blocks as the source of the clocking signal to the write head. The carrier for the read/write head includes a special pattern sensor that senses the data blocks in the data tracks before they pass beneath the write head. The pattern sensor output serves as the clocking signal to precisely control the placement of the write pulses by the write head. A time delay is calculated using a timing mark on the patterned disk to delay the write pulses so that a data block sensed by the pattern sensor is the same data block to which the write pulse is applied. In this manner the actual previously recorded data provides the synchronization or clocking signal to control the writing of the new data. The time delay is calculated from measurement of the time for a timing mark to pass from the pattern sensor to the read head and from known spacings of the pattern sensor, read head and write head on the head carrier.

摘要： Disclosed herein is a method of controlling the orientation of microphase-separated domains in a block copolymer film, comprising forming an orientation control layer comprising an epoxy-containing cycloaliphatic acrylic polymer on a surface of a substrate, irradiating and/or heating the substrate to crosslink the orientation control layer, and forming a block copolymer assembly layer comprising block copolymers which form microphase-separated domains, on a surface of the orientation control layer opposite the substrate. The orientation control layer can be selectively cross-linked to expose regions of the substrate, or the orientation control layer can be patterned without removing the layer, to provide selective patterning on the orientation control layer.
