    Abstract: In one embodiment a film can comprises a surface comprising a plurality of prism structures. Each prism structure has a lateral modulation in the w direction of less than or equal to ±20% of an average pitch of the prism structures. The plurality of prism structures can have a variation in the w direction of prism peak height that is discrete and/or continuous. In one embodiment, a method for making a film can comprise forming a plurality of prism structures on a surface. The plurality of prism structures can have a lateral modulation in the w direction of less than or equal to ±20% of an average pitch of the prism structures, and wherein the plurality of prism structures have a variation in the w direction of prism peak height that is discrete and/or continuous.

    Abstract: M sets of digital data obtained by adding a control bit to an n-bit data string are collected to generate 2.sup.m kinds of m(n+1)-bit data strings, with I-NRZI modulation being applied to these data strings to generate m kinds of I-NRZI modulated data strings and the I-NRZI modulated data strings are subject to spectrum analysis for the desired frequency components, in order to supply one of the I-NRZI modulated data strings as a recording signal based on the result of the spectrum analysis.
