Abstract
A disk hub for a removable cartridge is disclosed that has an enlarged center hollow, and a spindle motor is also disclosed that has a top protrusion that fits into the enlarged center hollow. The center hollow and protrusion have diameters at least as large as the outside diameter of a spindle motor top bearing. While the spindle motor is engaged to the hub, the top bearing projects into the center hollow, thereby efficiently using vertical space.
