Disclosed herein is a data recording apparatus which may include a recording data acquisition section, a data recording section, a file management section, a recording control section, and a file updating control section. In response to the electric force, an attractive force for attracting the conveyor belt to the platen is generated. In another arrangement, a portion of the rail and groove inter-engagement mechanism is segmented instead of continuous. According to other embodiments of the invention, two package dies, one a BSI image sensor, the other an FSI image sensor, are stacked on a common substrate such as a printed circuit board, and are operatively coupled together via redistribution layers.
