Abstract
An apparatus is capable of using a detachable recording medium. The apparatus has an electrical contact point that is electrically connected with the recording medium for a predetermined length in the recording medium insertion and ejection directions. An eject mechanism is incorporated to enable eject of the recording medium. A first detection device detects an ejecting movement of the recording medium at a first time. The first time is earlier than a break time when the electrical contact points is electrically disconnected from the recording medium. A second detection device detects the ejecting movement of the recording medium at a second time. The second time is earlier than the break time and later than the first time. The apparatus is capable of accomplishing necessary safety measures when the recording medium is ejected during data recording.
