Abstract
A system for exchanging digital data among a plurality of hand-held computer devices. Digital signals are written by a first hand-held device to a mini-cartridge that mini-cartridge is inter-operable among a class of hand-held devices, each of which is equipped with a mini-disk drive. A common digital data format is employed to further facilitate exchange of data between devices.
