Single Data Media Cartridge Loader with Multiple Input Slots

      Disclosed is a concept to improve the performance of a data
storage library with drives having two input slots.

The design of this invention, as illustrated in Fig. 1 comprises:

      An input means 7 with a plurality of receiving slots 21 for
receiving cartridges 3 inserted into by the picker 1.

      A loading means 9 which loads the media 8 of the one and only
one cartridge 3 left in the input means 7 to the drive 5, the input
means 7 can receive and store several cartridge, but the picker must
remove all cartridges except one which data is to be processed before
the media 8 of said cartridge can be loaded to the drive 5, the same
restriction is applied during the unloading process.  In a multiple
cartridge stack loader, the loading means 9 selects and loads the
media of a specific cartridge stored in the input means to the drive.
In this invention, the task of selection of cartridge is left to the
picker 1 by getting it to remove all unwanted cartridges, the loading
means just loads the media indiscriminately.  With this loader
concept, the cartridge exchanging process becomes:

Step 1: Move the picker to the new cartridge position,

Step 2: Pick the new cartridge with the picker,

Step 3: Move the picker to the drive loader (a long picker travel)
while unloading the media from the drive to the cartridge,

Step 4: Load the new cartridge into an empty slot of the input means,

Step 5: Move the picker to the old cartridge,

Step 6: Remove the old cartridge with the picker,

Step 7: Load the media of the new cartridge into the drive while
moving the picker to a storage receptacle (a long picker travel),

Step 8: Load the old cartridge into the receptacle.

The preferred embodiments of this invention, as illustrated in Fig. 2
comprise:

o   An input means 7 with a plurality of receiving slot 21 for
    receiving cartridge 3 inserted into by the picker 1, t...
