Specified pattern generating device of DCC consists of the frequency generator(11) which generates the signal frequency which is able to record in each channel by clock, the pattern selecting control part(13) which outputs frequency selecting signal according to the choice of user, the pattern selecting part(12) which selects the frequency which will be recorded in each channel among the output of frequency generator(11) according to the output of this pattern selecting control part(13), the pattern synthesizer which synthesizes the output of this pattern selecting part(12) as the signal to be compatible to DCC.
