生装置。[Scope of Claim for Utility Model Registration] A recording operation in which an analog signal to be recorded is passed through a low-pass filter and then converted into a digital signal by an analog/digital converter and recorded on a recording medium;
In a recording and reproducing apparatus that performs a reproducing operation in which a digital signal reproduced from the recording medium is converted into an analog signal by a digital/analog converter and then passed through a low-pass filter, an output terminal side that outputs a reproduced signal converted to an analog signal; a recording/reproduction common low-pass filter whose output side is connected to the input side of the analog/digital converter; and an input terminal into which an analog signal to be recorded is input to the input side of the recording/reproduction common low-pass filter during recording operation. 1. A recording and reproducing apparatus comprising switching connection means for connecting an input side of a low-pass filter for recording and reproducing to an output side of the digital/analog converter during a reproducing operation.
