The playhead on a turntable is a diamond. Sound comes from the diamond vibrating as it is dragged along some vinyl grooves. If the pressure from the diamond is too light or too heavy, it can badly damage the records it plays. The diamond is an extremely hard substance, and it can act as a cutting head if the pressure is to high. Conversely if the pressure is too light, the needle will bounce around in the groove as it plays. From what I've read, too light is more damaging than too heavy.how exactly does a turntable destroy records??
Vinyl records are relatively fragile. This particular family of turntables have ridiculously heavy weight when measured.
