摘要： A recording and/or playback apparatus of a dislike recording medium, such as optical disk, is equipped with a receiving portion, a recording and/or playback portion, an ejecting operation mechanism, a loading mechanism, and a positioning mechanism. In the receiving portion, a plurality of supporting portions supporting respective peripheral ends of a plurality of disklike recording media are formed in an annular form, and an opening portion is formed on the supporting portion. The recording and/or playback portion conducts recording and/or playback of the disklike recording media. The ejecting operation mechanism penetrates from the opening portion of the receiving portion and ejects a desired disklike recording medium out of the disklike recording media, from the supporting portion. The loading mechanism takes out the desired disklike recording medium, which has been ejected from the supporting portion by the ejecting operation mechanism, from the receiving portion and loads the desired disklike recording medium onto the recording and/or playback portion. The positioning mechanism rotates the receiving portion and makes the desired disklike recording medium and the loading mechanism oppose to each other.
