Abstract
In a mass storage library, a module storage array includes a back plate having apertures patterned to form a cartridge storage together with cell blocks that mate with the openings in the back plate. A column of cell blocks are held in place between a shelf and a spring load and include calibration targets to align the cell blocks to the library accessor and reader. One stripe the length of the storage cell stack contains a bar-code. The bar-code extends the entire length of the stripe and identifies the individual cell blocks when empty. A plurality of columns of cell blocks provide the complete storage array. Each column of the cell blocks include one stripe with a bar-code along its length that is directly fastened to the back plate with each cell of the column having a separate bar-coding on the strip. The accessor includes a sensor that reads the coding to provide an indication of an empty cell block.
