<p>PROBLEM TO BE SOLVED: To increase operation efficiency by a simple structure in a large- capacity recorder. SOLUTION: This recorder is provided with a medium housing case 2 for housing plural recording media 1 by lamination, a driving device 3 disposed near the upper stage of the medium housing case 2 to read or write the recording media 1, and a carrier unit 4 for carrying the recording media 1 from the medium housing case 2 to the driving device 3 and the used recording media 1 to the uppermost stage position of the medium housing case 2. The medium housing case 2 is constructed in such a manner that when the recording media 1 are carried by the carrier unit 4 to the driving device 3 side, the other recording media 1 positioned in the upper stages are sequentially downward moved so as to occupy the occupation positions of the recording medium 1 being used.</p> |
