Belt drive

A belt drive turntable uses a thin rubber or elastic belt looped around the motor pulley and the underside or edge of the platter, rather than connecting the motor directly to the platter. The belt physically separates the motor from the platter, which is the whole point of the design. Most manual and many automatic turntables aimed at home listening use this layout.

Because the belt absorbs and damps the small vibrations and electrical noise a motor generates, belt drive designs tend to have quieter backgrounds and less rumble reaching the record than a motor bolted straight to the platter would produce. The tradeoff is a slower start-up, since the belt has to grip and bring the heavier platter up to speed gradually, and belts stretch or perish over years of use and eventually need replacing.

When buying, check whether replacement belts are easy to find for that model, since a stretched or slipping belt is the most common reason a belt drive turntable starts running slow or speed becomes unstable. A quality belt should sit flush without visible fraying or glazing. A frequent point of confusion is assuming any turntable with a rubber mat is belt drive, when the drive mechanism is about how the motor connects to the platter, not what sits on top of it.
