Abstract
A checkerboard data storage library is provided which includes a plurality of receptacle modules and a plurality of picker modules. The receptacle modules and the picker modules are arranged alternately side by side in a closed loop planar array. Each receptacle module has a plurality of open-ended receptacles arranged one above the other in a column which extends perpendicular to the planar array. Each open-ended receptacle is capable of receiving and storing a recording medium. Each picker module has a picker which reciprocates vertically in a respective column opposite open ends of the receptacles in receptacle modules for transporting recording media therebetween. The above arrangement facilitates simpler expansion of the library and assures its operability even though one or two picker modules should fail.
