摘要： Methods to pattern substrates with dense periodic nanostructures that combine top-down lithographic tools and self-assembling block copolymer materials are provided. According to various embodiments, the methods involve chemically patterning a substrate, depositing a block copolymer film on the chemically patterned imaging layer, and allowing the block copolymer to self-assemble in the presence of the chemically patterned substrate, thereby producing a pattern in the block copolymer film that is improved over the substrate pattern in terms feature size, shape, and uniformity, as well as regular spacing between arrays of features and between the features within each array compared to the substrate pattern. In certain embodiments, the density and total number of pattern features in the block copolymer film is also increased. High density and quality nanoimprint templates and other nanopatterned structures are also provided.

摘要： PROBLEM TO BE SOLVED: To provide a PRML signal processing method for obtaining a highly reliable data demodulation by reducing an influence of a low frequency medium noise or a low frequency waveform distortion.
SOLUTION: For effectively suppressing a signal in a low frequency region where a medium noise or a signal distortion is concentrated, and also for effectively utilizing a detection signal component of the reproduced signal in the same signal region, a target of equalization process of a partial response waveform is set up with respect to a perpendicular recording/reproducing signal so as to suppress a low frequency signal component near DC to the specified amount for achieving both of the above purposes, and a maximum likelihood decoding process is carried out. A reliability of the data demodulation is thereby increased, and a signal quality is improved. As a result, a noise from a recording medium is further reduced, and the high density magnetic recording/reproducing device is configurable.
