Abstract: An information recording and reproduction apparatus has an eject slider 9 which is moved by the operation from the outside. An eject plate 2 as a mechanical driving means for constituting a loading mechanism is engaged with an eject lock lever 12, through which a driving force to the eject slider 9 is transmitted to the eject plate 2. During when information is being recorded into a recording medium 4, by that an eject latch magnet 15 is energized, an absorption plate 14 of the eject lock lever 12 is absorbed and the eject lock lever 12 is inclined, and therefore, a driving force which is applied to the eject slider 9 should not be transmitted to the eject lock lever 12, thereby resulting in preventing a driving force from being transmitted to the eject plate 2.
