Summary:A rotary drive apparatus for a disc (1), such as a micro-floppy disc, wherein when the disc (1) is mounted on a turntable (30), a central pin (31) arranged in the centre of the turntable (30) and a drive pin (32) arranged in a position away from the centre of the turntable (30) are respectively inserted in a central hole (4) of the disc (1) and a drive hole (5) formed at a position away from the central hole (4) of the disc (1), and the disc (1) is driven by the drive pin (32) due to rotation of the turntable (30), the drive hole (5) of the disc (1) being urged in a direction away from the centre of the turntable (30) by the drive pin (32), so that the periphery of the central pin (31) is pushed against the edge of the central hole (4), and the centre of the disc (1) coincides with that of the turntable (30). The drive pin (32) is moved in a direction opposite to the rotating direction of the turntable (30) and simultaneously gradually away from the centre of the turntable (30), when the disc (1) is driven by the drive pin (32), whereby a force that moves the drive hole (5) of the disc (1) in the direction away from the centre of the turntable (30) is increased in proportion to a torque load on the disc (1).
