<p>A guide rail mechanism (2), as a magnetic head guide device for guiding a magnetic head in the lateral direction of the magnetic tape, comprises a fixed guide rail member (8) secured to a base member (1), and a movable rail member (7) that is movable, in mesh with the fixed guide rail member (8), substantially together with a magnetic head (4). Linear guide grooves (9a, 9b) are longitudinally provided in the inner side walls of the movable rail member (7). Similarly, linear guide grooves (9c, 9d) are longitudinally provided in the outer side walls of the fixed rail member (8). A plurality of rolling members (10) are so fitted between the guide grooves (9a) and (9c) facing each other and between the guide grooves (9b) and (9d) as to roll in contact with these guide rail members.</p> |
