A removable disk cartridge drive has an eject member that moves from a forward position to a rearward position upon insertion of the cartridge from the drive. A coupling member extends between an eject button on the drive and a switch which energizes an electro-mechanical device to eject the cartrid

A removable disk cartridge drive has an eject member that moves from a forward position to a rearward position upon insertion of the cartridge from the drive. A coupling member extends between an eject button on the drive and a switch which energizes an electro-mechanical device to eject the cartridge when the switch is triggered. The coupling member is a clear plastic which transmits light to the eject button to indicate the presence of a cartridge in the drive.
