An apparatus (24) and method for selectively engaging and ejecting a cartridge (99) containing information storage medium. The apparatus comprises a frame assembly (42) and a drive (44) for driving the frame assembly along a path of axial displacement (84). Cartridge engagement members (46) are attached to the frame assembly for engaging a cartridge. A detector (50) is connected to the frame assembly in a manner to travel essentially in unison with the frame assembly as the frame assembly travels along the path of axial displacement. A cartridge ejector (52) is attached to the frame assembly and responsively coupled to the detector for ejecting a cartridge held by the cartridge engagement members when the detector and the frame assembly cease to travel in unison with one another. An solenoid actuator (100) has a plunger (104) which moves from a first position into a second position when a cartridge is to be ejected, thereby extending into the path of the detector so as to stop the axial displacement of the detector relative to the frame assembly.
