    Abstract: A flexible magnetic recording disk (18) is nonremovably enclosed in a rigid jacket (10). A wall (17) of the rigid jacket includes a movable wall-piece (29) which operates as a disk cleaning member. The disk is clamped to a spindle/collet drive assembly while the disk cleaning member is spaced from the adjacent surface of the disk. Only after clamping has been accomplished is the disk subjected to the friction force of the cleaning member.

    Abstract: A disk drive structure maximises the axial length available for mounting disks within a predetermined height such as dictated by a form factor. A cast aluminium box frame 12 is used which supports the spindle and actuator assemblies and forms a part of the head disk enclosure in cooperation with a drawn metal cover 10. The box frame captures the spindle 9 and actuator shafts 40 at each end to ensure maximum overall assembly stiffness and to minimise the axial length required by the structure supporting the spindle. The box casting geometry is angled to establish the casting/cover joint around the disks before the diameter of the disks parallel to the width form factor, so that only the thinner cover is interposed in the region where the disks most closely approach the form factor. The cover and box frame are sealed and secured to one another by a thin compliant tape 11 that does not contribute stress to the box frame during thermal cycling.

    Abstract: A magnetic transducer support assembly includes parrallel flexure spring supporting elements which are of sufficient length to approximate linear motion over the length of translational displacement used. The flexures are formed of a single continuous length of flat spring material, and built-up portions on the spring stretches between the base member and transducer carriage are provided to resist twisting and other unwanted motions induced by vibration and similar influences. Displacement is achieved by cam actuation driven by a stepper motor which may control multiple such transducer mountings on a single side of a disk or on opposite sides of a disk.
