Abstract
A pivotable door for a tape cartridge minimizes door opening space to be allocated within a tape drive and maximizes useable space within a tape cartridge closed by the door. The door may be an articulated two panel door having a top panel to be slid backward on a top cover of a cartridge with a lower panel which can be pivoted and drawn upwardly through arcuate channel guides to open a front and a top of the cartridge. A bottom panel can be slid into a retracted position on a bottom cover of the cartridge to expose a bottom opening of the cartridge. Alternatively, a one-piece pivotable door may be provided which is slid and pivoted along an axle on the top of the one-piece door on a top cover of the cartridge and guided by an arcuate edge guiding surface within the cartridge.
