An ejection inhibiting mechanism in a disk memory device of a meidum exchanging type has a latching solenoid for inhibiting the operation of an ejecting mechanism for ejecting a memory medium; an inhibit releasing device for releasing the inhibition of the operation of the ejecting mechanism by the operation of the latching solenoid when a predetermined time has passed after power of the disk memory device is stopped; and a storage battery charged at any time and supplying power to the latching solenoid and the inhibit releasing device. The operation of the ejecting mechanism is inhibited until the rotation of the memory medium is stopped. A cartridge for a disk constructing the memory medium is ejected after the power of the disk memory device is turned off and the rotation of the disk is completely stopped. An attractive state of the latching solenoid is released when the predetermined time has passed.
