Abstract
A recording head unit includes a base plate with a cut-out portion (or slot or through hole). A printed circuit board has a memory device attached to it and the printed circuit board is joined to the base plate with the memory device in the cut-out portion. The memory device is thinner than the base plate and fits completely within the cut-out portion, so that it is disposed wholly within the boundaries of the recording head unit. A recording cartridge includes a recording head unit and an ink tank for supplying ink to the recording head unit which are joined together, and a memory device which is substantially enclosed by joining the recording head unit and the ink tank.
