。[Claims for Utility Model Registration] ■ The digital signal recording/reproducing section is equipped with means for detecting errors, and an error flag corresponding to a code group containing an error is changed in voltage or current, and is monitored in real time by visual monitoring means. 1. A magnetic recording and reproducing device comprising means for monitoring amplitude changes. 2. In claim 1 of the utility model registration claim, the digital signal is a video signal, and the monitor means replaces the area corresponding to the error in the decoded video signal with specific fixed data, and the digital signal is D/A converted. At least a means for outputting at least one of a video signal or a video signal obtained by adding an analog pulse signal corresponding to an error to a video signal that is D/A converted without replacement in an analog manner using a visible monitor device such as a CRT is provided. A magnetic recording and reproducing device comprising:
