Magnetic clutch having apparatus for centering magnetic recording tape reel

摘要

Apparatus is described for improving a magnetic clutch assembly for holding a magnetic tape reel. The magnetic clutch assembly has a center pole piece which is positioned during loading of the tape reel in an aperture of the tape reel base. The center pole piece distal end includes a non-magnetic pole piece which reduces the influence of the magnetic force on the tape reel during loading.
