1. A magnetic disk drive, comprising:

  • a magnetic disk in which information is written;

    a magnetic disk driving mechanism that rotates the magnetic disk; and

    a magnetic head mechanism including a magnetic head that reads and/or writes information on the magnetic disk, and a magnetic head driving mechanism that drives to move the magnetic head relative to the magnetic disk;

    the magnetic disk, the magnetic disk driving mechanism, and the magnetic head mechanism being housed inside an enclosure that restrains the flow of air from the outside, wherein the magnetic disk drive includes a membrane electrode assembly configured to adjust the humidity inside the enclosure, and a dehumidifying passage that restrains an inflow of water molecules between a dehumidifying face of the membrane electrode assembly and the inside of the enclosure.
