Eli5: Why does dj-ing not wreck the record they’re scratching on?
In: 40
It does wear it down. In fact regular play wears down the record which is a negative of vinyl records. When they’re scratching they’re not pushing the needle down harder but they are spinning the record, and usually a specific part of it, faster across the needle and this accelerates wear. That being said it takes a lot of use to wear it down to the point where it’s unusable and especially for DJs it doesn’t matter as much. Sure a small part of each record is worn down but since it’s played highly accelerated or distorted they don’t care to maintain the quality perfectly, it’s hard to tell for the audience anyways due to the volume.
DJs also generally have multiple copies of records.
