Picking/Moving Cartridges by Grasping Magnetic Hub with an Electromagnet

      In its most general sense, removable media needs to be moved
from place to place.  This occurs in the manufacturing environment,
in Automated Cartridge Loaders (ACLs), and in libraries.

      Removable media is typically attached magnetically to the drive
clutch of the target device.  The removable media has a metal button
and the drive clutch has a hold-down magnet.  Proposed is the use of
that same metal button on the removable media to also move the media
from point to point.

      Specifically, proposed is the sequential use of a long series
of thin-film electromagnets to move the removable media along a path.
The electromagnets could be made by the same thin-film processes as
used to make integrated circuits.  As the removable media was
transported, different thin-film electromagnets would energize to
continue the motion.  These electromagnets could be deposited on the
substrate of whatever mechanism was transporting the media, e.g., the
tray of the picker mechanism.

      Effectively, this would constitute a linear motor or linear
actuator for moving the removable media (a) between its home slot in
a library and the picker mechanism or (b) between the picker
mechanism and the target device.  Additionally, this linear motor
could be used to transport the removable media through the
manufacturing process or through an intervening ACL between the
library picker and the...
