A method for assembling a library apparatus for storing cartridges accommodating memory media therein, comprising a reference unit, at least one accessor unit, at least one passage unit arranged between the reference unit and the accessor unit, at least one drum unit with a plurality of cells for storing the cartridges accommodating the memory media, at least one drive unit provided on at least one side of the reference unit for recording on and regenerating from the memory media accommodated in the cartridges, at least one guide rail provided through the reference unit, the accessor unit and the passage unit, and at least one accessor provided in the accessor unit to be movable on the guide rail, for transporting the cartridges between the drum unit and the drive unit, wherein the method comprises the steps of:

• extending a thread in a tensioned state at a height from a floor surface around four poles positioned at four corners of an area wherein the library apparatus is to be installed while positioning the reference unit at a center thereof as a reference locker, and marking a position at which each of the accessor, the passage, the drum and the drive units is to be installed on the floor;
• installing the reference unit to coincide with the mark while adjusting footings thereof so that the reference unit is vertical to the floor surface;
• installing the at least one passage unit on at least one side of the reference unit in accordance with the number of the at least one drum unit to be coupled to the library apparatus and connecting signal cables in both the passage and the drum units with each other;
• coupling the guide rail in the passage unit and the reference unit to each other while adjusting footings thereof so that the height of the passage unit coincides with that of the reference unit;
• arranging the accessor unit adjacent to one end of the passage unit and connecting signal cables in both the accessor and the passage units with each other;
• coupling the guide rail in the accessor unit to those in the passage unit while adjusting footings thereof so that the height of the accessor unit coincides with that of the passage unit;
• arranging the drum unit adjacent to a side of the passage unit to coincide the heights and inclinations of both the drum and the passage units with each other;
• and
• detaching a manual mount cell from the drive unit and instead attaching an accessor mount cell to a position from which the manual mount cell has been detached;
• and fixedly securing the drive unit to the reference unit.

A library apparatus having a plurality of cells for storing cartridges accommodating memory media therein, the library apparatus being used for data retrieval requiring a large capacity, and comprising:

• a reference unit arranged at a center of the library apparatus;
• at least one accessor unit arranged at at least one longitudinal end of the library apparatus;
• at least one passage unit arranged between the reference unit and the accessor unit;
• at least one cell unit with a plurality of cells for storing the cartridges accommodating the memory media;
• at least one drive unit provided on at least one side of the reference unit and including recording/regenerating means for recording on and regenerating from the memory media accommodated in the cartridges;
• at least one guide rail provided through the reference unit, the accessor unit and the passage unit;
• at least one accessor provided in the accessor unit to be movable on the guide rail for transporting the cartridge between the cell unit and the drive unit;
• a cartridge feeder for the entry/exit of the cartridges relative to the recording/regenerating means;
• and
• a housing configured for accommodating the cartridge feeder and including a plurality of storage cells for storing the cartridges and an area configured for mounting a selected one of a manual mount cell and an accessor mount cell, the manual mount cell having a first fixing member for fixing the manual mount cell to the mounting area when the manual mount cell is selected, and the accessor mount cell having a second fixing member for fixing the accessor mount cell to the mounting area when the accessor mount cell is selected, the accessor mount cell further including an entry cell for storing cartridges to be inserted into the recording/regenerating means by the cartridge feeder, and an exit cell for storing cartridges removed from the recording/regenerating means by the cartridge feeder, the accessor being configured for inserting the cartridges into the entry cell and removing the cartridges from the exit cell.

A method for using a drive unit for recording/regenerating on and from memory media in a library apparatus as a common unit for a manual mount cell and an accessor mount cell, the library apparatus having a reference unit arranged at a center of the library apparatus, at least one accessor unit arranged at at least one longitudinal end of the library apparatus, at least one passage unit arranged between the reference unit and the accessor unit, at least one cell unit with a plurality of cells for storing the cartridges accommodating the memory media, at least one guide rail provided through the reference unit, the accessor unit and the passage unit, and at least one accessor provided in the accessor unit to be movable on the guide rail for transporting the cartridges between the cell unit and the drive unit, said method comprising the steps of:

• providing the drive unit, including recording/regenerating means for recording on and regenerating from the memory media accommodated in the cartridges, on at least one side of the reference unit;
• placing a cartridge feeder for the entry/exit of the cartridges relative to the recording/regenerating means;
• configuring a housing for accommodating the cartridge feeder and for mounting a selected one of the manual mount cell and the accessor mount cell thereon, the manual mount cell including a plurality of storage cells for storing the cartridges, the accessor mount cell including an entry cell for storing cartridges to be inserted into the recording/regenerating means by the cartridge feeder, and an exit cell for storing cartridges removed from the recording/regenerating means by the cartridge feeder;
• and
• configuring the accessor for inserting the cartridges into the entry cell and removing the cartridges from the exit cell.
