Abstract
A disc drive for a flexible magnetic disc includes a frame, a pivoted cover, a turntable spaced from a spindle-mounted disc clamping cone, and a lever for cooperating with the cone to move it toward and away from the turntable. The lever is mounted on the frame about a pivoting axis. As the cover is closed, a cover mounted roller contacts the lever at a point spaced a distance from the lever pivoting axis. This distance continuously increases until the disc is clamped for operation. The stationary members for the spindle and the turntable are a unitary part with the frame. The members are machined to their final dimensions in one operation.
