Exemplary embodiments include methods, systems, and storage mediums for providing multi-media content storage and management services. Each cylinder is configured as a low air loss system to allow air to flow into the cylinder from a source and out of the cylinder through small holes located on the top of each cylinder. A gear linkage including a four gear anti-lash arrangement with a movable gear accommodates variation in distance between hubs of different sets. The clamp mount device can have a pin or another positioning member to maintain the position of the clamp along the rail.
