    摘要： A clothespin-like gripper (18) has a pair of clamp jaw portions (48) resiliently urged together and adapted to frictionally embrace and thereby grip a magnetic diskette (22) or disk-jacket assembly for pulling the diskette (22) from an original position in a diskette magazine (28) into a final position for data transfer. A swingable blocker (20) is provided on the gripper (18) so that the diskette (22) may be selectively blocked from being embraced by the gripper (18) whereby the gripper (18) may be used to move the diskette (22) back from its final position into its original position without any embracing action by the gripper (18).

    摘要： A disk drive is fabricated in such a manner as to have very little tracking error caused by manufacturing tolerances on the subassemblies making up the drive. In the disk drive, head (18) is carried by a swing arm head carrier (20) indexed to individual track positions by an indexing cam (24) having the same axis (54) of rotation as a disk spindle (16). The head (18) is positioned and fastened in its carrier (20) only by reference to the axis of rotation (54) after the carrier (20), cam and spindle (16) have been secured. The drive is fabricated by assembling the head carrier (20), the disk spindle (16) and the indexing cam (24) on the drive frame (31) and thereafter fastening the head (18) to the carrier (20). Prior to fastening the head to the carrier, the head is precisely referenced to the axis of rotation (54) of the recording disk and the indexing cam (24). The head is fastened to the carrier by an acrylic ultraviolet curing adhesive. The adhesive is applied between the head and the carrier before the head is positioned relative to the axis of rotation. After the head is in the proper position, the adhesive is cured by exposing it to ultraviolet light.

    摘要： A drive machine is described for magnetic diskettes of the type including a flexible disk rotatably disposed in a jacket having aligned radial slots in the two thicknesses of the jacket. The machine includes a pair of transducers (28, 30) fixed to a carriage (26) and extending through one of the slots into contact with one side of the disk (48) and a pair of backup pads (36, 38) on the other side of the disk respectively opposite the transducers and mounted by on swing arms (94, 96) hinged to the frame of the machine. A motor driven cam plate (32) with a spiral groove and a follower (114) therein are used for moving the transducer carriage (26) radially on the disk for registry with different magnetic tracks thereon, and the cam plate has a peripheral portion (120) that moves the swing arms to disengage the pads from the disk at outermost magnetic tracks of the transducers. The disk is clamped between a rotatable drive spindle (24) and a collet (40), and the collet is carried on a further swing arm (112) hinged to the machine frame. Interconnections are provided between the swing arms so that when the collet is moved out of engagement with the spindle the pads are also moved out of engagement with the disk.
