The vinyl burner records sound onto a vinyl record through a driving circuit. During the vinyl recording process, the engraving knife rapidly vibrates up, down, left, and right on the vinyl record to record the sound signal onto the vinyl record. This requires the engraving knife head to be sharp enough and hard enough in texture. Diamond has a Mohs hardness of 10 and is hard in texture. Choosing diamond as the cutting head can increase its service life.
