Abstract: Provided herein is a method, including forming a first template including a first pattern, wherein forming the first template includes self-assembly of diblock copolymers guided by an initial pattern; forming a second template including a second pattern, wherein the second pattern corresponds to a servo pattern; and forming a master template from the first template, wherein the master template includes one or more portions of the first pattern combined with the second pattern.

Abstract: A method for encoder frequency-shift compensation includes determining frequency values of an input encoder signal, determining repeatable frequency-shifts of the frequency values and generating a frequency-shift compensated clock using the repeatable frequency-shifts. A frequency-shift compensated clock includes a synthesizer configured to generate a frequency-shift compensated clock signal using repeatable frequency shifts and encoder clock signals.
Abstract translation: 一种用于编码器频移补偿的方法包括：确定输入编码器信号的频率值，确定频率值的可重复频移，并使用可重复的频移产生频移补偿时钟。 频移补偿时钟包括合成器，其被配置为使用可重复的频移和编码器时钟信号来产生频移补偿的时钟信号。
