A magnetic recording medium achieves excellent noise reduction by controlling the crystal orientation of a magnetic layer without thermal processing. A first controller calculates and outputs an active current instruction value by proportional-plus-integral control to perform proportional integration of a deviation between the value of a DC voltage outputted from the converter section and a DC voltage instruction value. In embodiments, the device can also include integrated load protection and load diagnostics. With the multilayer structure, the object of the invention can be accomplished. The tank body includes a throat that extends outwardly from a portion of the tank adjacent the port, and a portion of the nozzle member comprising the first plurality of perforations is disposed within the throat. The thermal enhanced cover is disposed on the carrier to expose at least one side of the light emitting chip.
