The invention relates to an optical disk drive, which can be built very small. The structures used in the molding process are formed by tooling that creates the shapes of the microelements in a material deposition step, and also creates the sizes and shapes of the openings that will be formed by the fluidic jets. A third receiving room is defined in the insulative housing and extends forwardly from the rear face as well. The pads are located in the non-display region and electrically connected to the pixel array. Finally, the executable instructions are received and calculated by a tool path calculator to produce a plurality of points along the tool paths. More particularly, the invention relates to transformers using transducers such as generators and actuators.
