記録再生装置。[Claims for Utility Model Registration] Magnetic recording that sets the optimum value of the recording signal level by utilizing changes in the reproduction signal level obtained when reproducing a recording medium on which recording has been performed by changing the recording signal level. In the playback device, a first storage means stores a playback signal level when a reference tape is played back as a reference level, a second storage means stores the recorded signal level, and a playback signal level of the recording medium and the first storage means store the playback signal level when the reference tape is played back. an optimum value detection means for detecting a reproduction signal level corresponding to the reference level by comparing the output of the first storage means; and an optimum value detection means for detecting a reproduction signal level corresponding to the detected reproduction signal level from the second storage means; , and optimum value setting means for setting this as the optimum value of the recording signal level.
