Abstract
The present invention provides a method for selectively storing data files on a multiple volume cartridge (MVC) device which maximizes the likelihood of gaps in stored data appearing at the end of a cartridge. All incoming data files are initially stored in a virtual disk buffer, and checked to determine time of expiration. The expiration information is then used to reorder the virtual data volume files when placed on the MVC device so that the last to expire is stored first, and the first to expire is stored last.
