A method and system for manufacturing a perpendicular magnetic recording head is disclosed. An interface is provided between a merchant or the merchant’s bank and the bank or banks at which the consumer has accounts for card-based transactions. The cathode includes a plurality of emitters for emitting primary electron beams, arranged apart from one another on a circle centered at an optical axis of a primary electro-optical system. The second electrical connector is operably connected to a probe component energy transmission element and to a clamp component temperature sensor. In one embodiment, a user interface provides a single pane through which a user can access the media player application and its CD burning functionality.
