An apparatus and process for the rendering unintelligible of data stored on digital and analog recording media employs a means for embossing the media and a means for driving the media to traverse a path defined by the means for embossing. In one embodiment, the means for embossing includes knurled rollers that distort the surfaces of recording media passed therebetween. In one embodiment, the means for driving the recording media through the means for embossing includes a motor and at least one drive gear operatively associated with the means for embossing. The process for rendering recorded data unintelligible includes the steps of providing a means for embossing, providing a means for driving recording media through the means for embossing, and urging recording media through the means for embossing.
