A phonograph, later called a gramophone (as a trademark since 1887, as a generic name in the UK since 1910), and since the 1940s a record player, or more recently a turntable, is a device for the mechanical and analogue reproduction of sound.
Twin turntables were illustrated in the BBC Handbook in 1929, and were advertised for sale in Gramophone magazine in 1931. [3] There was an obvious need for such a setup when the normal music format was 78rpm records that played for five minutes at most and a classical symphony came in a box which might contain ten discs or more.
The first direct-drive turntable was invented by Shuichi Obata, an engineer at Matsushita (now Panasonic), [11] based in Osaka, Japan. [9] It eliminated belts, and instead employed a motor to directly drive a platter on which a vinyl record rests. [ 12 ]
Early belt-drive turntables were unsuitable for turntablism and mixing, since they had a slow start-up time, and they were prone to wear-and-tear and breakage, as the belt would break from backspinning or scratching.

Turntable, the circular rotating platform of a phonograph (a.k.a. record player, gramophone, turntable, etc.), a device for playing sound recordings.; Turntablism, using the device as a modern musical instrument
In a direct-drive turntable the motor is located directly under the center of the platter and is connected to the platter directly. It is a significant advancement over older belt-drive turntables for turntablism, since they have a slower start-up time and torque, and are prone to wear-and-tear and breakage, [5] as the belt would break from backspinning or scratching.
