摘要：
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.
