compact shelving

n. (also compact storage, mobile shelving, mobile aisle shelving, movable shelving) high-density storage consisting of mobile rows of shelving

Notes

By moving rows together, it is possible to eliminate aisles. An aisle can be created between two any rows as needed. Generally rows are parallel to each other, although they may be on a central pivot. Depending on the system, compact shelving may be moved using a manual crank or an electric motor.
