A disk loading mechanism includes disk cartridge positioning pins integrally formed in the base of a chassis portion thereof. In addition, at one side of the base of the chassis, a hooked portion is provided for securing a printed ciruit board to a lower side of the chassis. In addition, the base plate of the chassis mounts a damper fox smoothly controlling slider movement in a recess such that an overall height of the unit is reduced. According to such construction, reliable operation is assured with a reduced number of parts, such that manufacturing complexity and costs can be significantly reduced.
