Abstract
An improvement on the information record/reproducing apparatus, utilizing a tunnel current generated in a flat information recording medium by a needle-shaped probe electrode positioned close to the recording medium. In order to prevent deterioration of the probe and the recording medium by the atmosphere, these components are hermetically sealed in a container, with or without the driving mechanism. The sealed structure is made detachable from the main apparatus, thus facilitating manufacture, replacement and maintenance.
