ABSTRACT:
A disc recording and/or reproducing apparatus with a radio receiving function wherein a recording/playback unit having a high-frequency clock generator is housed in a shield case, and both input and output signals of the recording/playback unit are transferred to and from other circuits via a pair of filter disposed inside and outside the shield case, or such input and output signals are transferred via opto-electric convertor and electro-optical convertor disposed inside and outside the case, so that any unrequited high-frequency components radiated from input and output connection leadwires piercing through the shield case can be suppressed to consequently achieve remarkable reduction of the high-frequency noise entering into the radio receiving unit.
