DJ turntables can potentially damage records if not used or maintained properly. The two main ways records can be damaged are through excessive scratching and through incorrect tracking force. Scratching excessively can lead to audible degradation of the record over time, while a tracking force that’s too heavy can lead to physical damage such as record grooves being squashed or pushed out, which again degrades the record’s sound quality. It is important to use a stylus with adjustable tracking force and to be mindful of scratching technique. Some DJs opt to use special “scratch” records that are designed to withstand more wear and tear.
