  • Patent number: 4315289
    Abstract: A drive machine 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 extending through one of the slots into contact with one side of the disk and a pair of backup pads effective on the other side of the disk respectively opposite the pair of transducers and swingably mounted by swing arms to the frame of the machine. A motor driven cam plate with a spiral groove and a follower therein are used for moving the transducers radially on the disk for registry with different magnetic tracks thereon, and the cam plate has a peripheral portion that moves the swing arms to disengage the pads from the disk at outermost magnetic tracks for the transducers. The disk is clamped between a rotatable drive spindle and a collet, and the collet is carried on a swing arm mounted on the frame.

  • Patent number: 4226570
    Abstract: A clothespin-like gripper having a pair of clamp jaw portions resiliently urged together and adapted to embrace and thereby grip a magnetic diskette or disk-jacket assembly for pulling the diskette from an original position into a final position. A swingable blocker is provided on the gripper so that the diskette is thereby blocked from being embraced by the gripper whereby the gripper may be used to move the diskette back from its final position into its original position without any embracing action by the gripper.
