Abstract

A housing for enclosing a measuring apparatus for a hard disk recording medium and a recording apparatus for recording a signal on the hard disk recording medium is provided with a fan including a high efficiency particulate air filter. The fan blows air onto the hard disk recording medium and the recording apparatus under measurement through the high efficiency particulate air filter at a substantially constant air temperature and at a substantially constant air flow rate. An automatic door is located at a position other than an air protection area which includes positions of the hard disk recording medium under measurement by the recording apparatus and the recording apparatus, and includes a predetermined surrounding area. The automatic door shields the other area from the air protection area in the housing for enclosing the measuring apparatus under no measurement.
