黑膠唱盤依照馬達傳動方式，可以分為直接驅動、皮帶驅動與惰輪驅動三種。在大多數玩家心中，皮帶驅動才是 Hi End 作法，由馬達直接驅動轉盤，則是常見於低價入門唱盤的設計。

Record Clamp for High-end Turntables

Jakutis turntables are made from high quality materials: stainless steel, bronze, brass, granite, specific woods, processed using the latest technology (cnc machining, plasma coating and others). The selection of all technical solutions is based on the given acoustical requirements. Serious consideration is given to the appearance of the turntable, as a good-sounding turntable must be also be a good-looking object in the user’s home.
The turntable consists of a very heavy table utilizing spherical rubber dampers to support a heavy sub-chassis. The sub-chassis carries a heavy platter as well as the tonearm. This assembly (the tonearm,platter and sub-chassis) constitute a single, independent structure, floating on spherical dampers. A low-power but extremely stable synchronous motor is located on the table and drives the platter via a belt.
