Abstract

This article describes a tool providing a means of manually lifting a magnetic disk off of a storage or spindle stack in a manner consistent with a clean environment by providing a means of edge gripping a disk with three trapping surfaces A-1, A-2, and A-3, each having a disk embracing notch G. To remove a disk from a file product, the operator places the tool over the disk so that the notches G encompass the disk edges. By squeezing the handle elements B and C together, the disk can be gripped securely and lifted off the file hub. Contact with the disk takes place only at the outer diameter of the disk, and data surfaces will not be touched. The trapping surfaces A-2 and A-3 are fixed, and the surface A-3 is movable.

Magnetic Disk Lifter Tool

This article describes a tool providing a means of manually lifting a magnetic disk off of a storage or spindle stack in a manner consistent with a clean environment by providing a means of edge gripping a disk with three trapping surfaces A-1, A-2, and A-3, each having a disk embracing notch G. To remove a disk from a file product, the operator places the tool over the disk so that the notches G encompass the disk edges. By squeezing the handle elements B and C together, the disk can be gripped securely and lifted off the file hub. Contact with the disk takes place only at the outer diameter of the disk, and data surfaces will not be touched. The trapping surfaces A-2 and A-3 are fixed, and the surface A-3 is movable. The surfaces are moved into contact with the disk with the notches G embracing the edges of the disk by manually squeezing the double flexure connected links B toward the fixed link C. The squeez ing action moves the one movable trapping surface A-1 toward the dashed line position D. A helper spring may be added between the surfaces E to assist the flexure restoring force for improved tool release. Use of flexure pivots minimizes the potential for contaminant generation present in conventional pivots which might exist in a grip mechanism. The tool enables removing a magnetic disk from confining surroundings such as a file product for future evaluation uncontaminated by the removal activity.
