There is provided a magnetic recording/reproduction device which can appropriately supply lubricant to a metal-thin-film magnetic tape () containing no binder in a recording/reproduction surface even when the magnetic recording/reproduction device needs to be continuously performing recording/reproduction by using the magnetic tape () for a long time. The magnetic recording/reproduction device includes a lubricant supplier () which can supply lubricant to the magnetic tape () while the magnetic head () performing recording/reproduction on the magnetic tape (). With this configuration, the lubricant supplier () can appropriately supply lubricant during recording/reproduction even to the magnetic tape () used in a magnetic recording/reproduction device that needs to keep continuously operating for a long time.

Magnetic recording/reproduction device for metal-thin-film magnetic tape

A fuel cell body has an anode having an anode-side separator with projections and depressions formed on its surface, a cathode, and a membrane electrode assembly disposed between the anode and the cathode, and the fuel cell body is disposed in a container for storing liquid fuel so that at least the anode side is immersed therein. Fuel passageways through which the liquid fuel flows are formed by regions surrounded by the projections and depressions on the surface of the separator and the membrane electrode assembly. By this, the downsized, simplified and lower power consuming structure of auxiliary equipment such as a fuel feed system is achieved.
