Abstract:
1. A magnetic tape device comprising: a magnetic head arranged between two reels around which a magnetic tape is wound and configured to contact one side of the magnetic tape spanned between the two reels, the magnetic head being rotatable about a rotation axis parallel to a tape surface of the magnetic tape and perpendicular to a running direction of the magnetic tape; a contact member arranged between the two reels and configured to contact the other side of the magnetic tape; a base member rotatable about the rotation axis and provided in a position where the magnetic head and the contact member face each other with respect to the rotation axis, the base member being configured to move freely in a direction in which the base member intersects with the magnetic tape in a plane including the running direction of the magnetic tape and perpendicular to the tape surface of the magnetic tape in a state of being capable of receiving a rotational driving force from the driver; a driver configured to rotationally drive the base member and the magnetic head about the rotation axis so as to move and press the magnetic head against the one side of the magnetic tape; and a controller configured to cause the driver to generate a driving force for pressing the magnetic head against the one side of the magnetic tape and at the same time, for pressing the contact member against the other side of the magnetic tape, while keeping the magnetic head and the contact member in contact with the magnetic tape.
