ABSTRACT:
A digital code conversion system in a magnetic recording apparatus for converting one bit of an input digital signal into a signal of two bits, in which the number of binary digits of "0" making appearance between adjacent binary digits of "1" is two at minimum and seven at maximum. In the digital code resulting from the code conversion, ratio between maximum and minimum values of the density at which the binary digit of "1" makes appearance is 1:2.
