ABSTRACT:
A disc drive includes a motor and a turn table mounted on a shaft of the motor to be driven thereby. The turn table includes a lower drive member driven by the motor, and a positioning member mounted on the drive member. The positioning member includes a top surface on which the disc is mounted. The positioning member and drive member form a concave/convex interface, enabling the positioning member to float relative to the drive member to a position wherein the top surface (and disc) is oriented horizontally, even if the drive member becomes tilted relative to the shaft. The interface includes interengaging ridges and grooves to minimize friction and produce a positive rotary drive from the drive member to the positioning member.
