Claims

[Scope of utility model registration request]

a noise reduction circuit that decodes the playback input and outputs it as a line output and a recording output when a playback instruction is issued, encodes the line input and outputs it as a record output when a recording instruction is issued, and outputs the line input as it is as a line output; The first tape deck is configured to be capable of at least a playback operation, and the second tape deck is configured to be capable of recording/playback, and a noise reduction circuit selects a playback output of a magnetic tape loaded in the tape deck set to a playback state. In a magnetic recording and reproducing apparatus, the magnetic recording and reproducing apparatus includes a first selection means for supplying the input as a reproduction input, a second selection means for selecting either the line input or the recording output from the noise reduction circuit as the recording input; A level meter drive circuit that is switched in conjunction with the second selection means and selects either the line output output from the noise reduction circuit or the line input input to the noise reduction circuit to drive the level indicator. 3rd supply to
1. A magnetic recording and reproducing device comprising: selection means.
