发明名称 FM audio record reproducing apparatus.
摘要 <p>A reproducing apparatus which is provided with: frequency converting means (21) for performing frequency conversion of the FM regenerative signals respectively from the read heads, on the basis of frequency conversion signals each having a frequency different from the frequency of the carrier; voltage-controlled oscillators (22) for generating the frequency conversion signals, respectively; phase comparators (23) for comparing phases of two FM regenerative signals frequency-converted by the frequency converting means (21) in the overlap period so as to produce a difference signal corresponding to the difference between the phases; switching circuits (25) for feeding the difference signal generated by the phase comparators (23), into one of the voltage-controlled osciallators (22) generating the frequency conversion signal for frequency conversion of succeedingly reproduced one of the FM regenerative signals in the overlap period; and loop filters (24) for stabilizing a loop system constituted by the aforementioned parts; whereby the phases of two frequency-changed FM regenerative signals are made to coincide with each other before the switching of the output in the overlap period.</p>
