Abstract
A universal disk drive system (30) incorporates multiple read/write heads (204) supported on a rotatable carousel assembly (180) for selective positioning and alignment relative to a flexible magnetic disk on a drive spindle (120). A disk is received and fed along an input path to the drive spindle (120) by feed rollers (36,38) driven in unison. A clamp cone assembly (90) is mounted for movement relative to the drive spindle (120) for clamping either one of two predetermined sizes of disks against the drive spindle with coaxial inner and outer clamp cones (102, 104). The carousel assembly (180) includes a spider (186) supported for rotation about an angled spindle support (158). A read/write head (204) is supported on each angled arm of the spider (186) for precise radial and pivotal alignment relative to the disk by means of a slidable carriage (220) and azimuth adjustment module (246). Rotation of the carousel assembly (180) is controlled by an index and locking assembly (320).
