A perpendicular magnetic recording head includes a first magnetic portion, a second magnetic portion formed with a gap from the first magnetic portion, and a coil layer located in the gap between the first magnetic portion and the second magnetic portion for applying a recording magnetic field to the first magnetic field and the second magnetic field. The layered mediation sitting cushions and mats combine a slow recovery visco-elastic foam, having load deformation properties and densities, with one or more base layers of a batting support. A vertical actuator has a cover end attached to the bottom cover and a support end attached to the support structure, and is arranged to move the bottom cover vertically in a removal operation of the bottom cover. The printer driver starts the second application program, transfers settings of the printer driver to the second application program, receives the second print job formed by the second application program through the operating system, processes the second print job, and allows a printer to print the second print job. The controller is operable to control one or more of the plurality of capacitors to vary an operating parameter of the NFC device. The positioning slot includes a linear portion and a radial portion.
