, a formerly competing technology. Both technologies allow an ordinary user to remove and replace the cartridge containing the recording medium without special training. However REV places the read/write heads in the drive instead of inside the cartridge, which means that the drive's loading/unloading mechanism must mechanically insert heads into and remove them from the cartridge through a physical hole. By eliminating the need for this, RDX turns the drive into a dock—whose loading mechanism simply establishes an electronic connection to the cartridge.
