Abstract

A method for drive unit detection of an automated gripper mechanism within an automated tape library is disclosed. The drive unit automatically detects the physical presence of the mechanical gripper within the load mechanism envelope of the drive unit, preventing damage to the drive unit or library gripper.

Drive Unit Sensor to Detect Presence of a Gripper in an Automated
Tape Library

      A method for drive unit detection of an automated gripper
mechanism within an automated tape library is disclosed.  The drive
unit automatically detects the physical presence of the mechanical
gripper within the load mechanism envelope of the drive unit,
preventing damage to the drive unit or library gripper.

      The Figure shows a tape cartridge inserted into the drive
loader.  This is a side view of the loader with the cartridge being
inserted or retracted from the left, or front, of the loader.
Attached to the top plate of the loader mechanism is a sensor.  The
sensor is angled such that it does not detect the front edge of the
tape cartridge, but just beyond the edge.  Should the sensor detect
an obstacle in this area, such as an automated tape library gripper,
the load tray will not be lowered (cartridge will not load), or
raised (cartridge will not unload), until such time that the obstacle
is no longer detected.
