Abstract
An arrangement is disclosed for cutting information into a record carrier made of metal, particularly of copper by means of a diamond, with the diamond body being adjusted for cutting under a canting angle and being ground in such a manner that, deviating from the prior art manner, the cutting edge does not coincide with a diamond zone of optimum hardness but deviates from the optimum position by an angle which is preferably equal to the canting angle.
