A selectively openable closure mechanism for a magnetic recording disc cartridge for cooperating with a probe member connected to a disc drive unit provides for selectively opening access through an aperture in the cartridge to the interior thereof when the cartridge is inserted into the drive unit and the closure-actuating probe member is received into the cartridge and for closing access to the aperture when a cartridge is removed from the drive unit and the probe member is withdrawn from the cartridge, the mechanism including an arcuate guide track formed in at least one of the top or bottom panels of the cartridge, at least one arcuate door slidably carried by the guide track for selective movement between a closed position and an open position and structure connected to the door for engaging and capturing the probe member upon its reception into the cartridge and for driving the door from the closed position to the open position and back to the closed position upon insertion and withdrawal of the probe with respect to the cartridge, with the capturing structure preventing withdrawal of the probe from the cartridge except when the door is substantially in the closed position.
