- the medium is taken out by the other free hand (lower hand 22 in the example shown in FIG. 5) different from the hand from which the medium was taken out (FIG. 5 (c)).
- the new medium 50B taken out of the slot in step S12 or step S; 3 is loaded into the recording / reproducing device 30 (steps S15, S23 in FIG. 4, FIG. 5 (d)).
- the spindle medium starts rotating again after the loading of the new medium 50B, and the new medium 50 is accessed (step S24).
- the hand holding the old medium 5 OA (the lower hand 22 in the example shown in FIG. 5) and the old medium slot (the top slot in the example shown in FIG. 5) It is determined whether it is possible to directly access 121 A) (step S16), and in the example shown in FIG. 5, it is impossible to directly access the uppermost slot 121A with the lower hand 22.
- a slot other than the upper two slots in which the slot of the old medium can be directly accessed by the lower hand 22 holding the old medium If so, the old medium is accommodated in the slot of the old medium by the hand now holding the old medium (step S17).
- step S16 the hand holding the old medium (the lower hand 22 in the example shown in FIG. 5) is inserted into the slot of the old medium (the top slot 121A in the example shown in FIG. 5). If it is determined that direct access is not possible, the process proceeds to step S18, where the old medium is temporarily stored in the temporary slot 13 (FIG. 5 (e)), and another hand (in the example shown in FIG. ), The old medium is taken out of the temporary slot 13 (step S19), and the old medium is taken out of the temporary slot 13 by the hand (the upper hand 21 in the example shown in FIG. 5). 5 OA is stored in the slot corresponding to the old medium (the top slot 121A in the example shown in FIG. 5) (step S17, FIG.
- FIG. 6 is a schematic configuration diagram showing a second embodiment of the medium access device with a medium exchange function of the present invention, including the second embodiment of the medium exchange device of the present invention.
- the medium access device 100 with a medium exchange function shown in FIG. 6 has a medium storage unit 10, a medium transfer unit 20 and a recording / reproducing device, similarly to the medium access device with a medium exchange function shown in FIG. 30 and a control device 40 are provided, and the medium delivery unit 20 is arranged at a position between the medium storage unit 10 and the recording / reproducing device 30.
- the medium accommodating section 10 is provided with a magazine accommodating section 11 for accommodating only one large magazine 50 having eight slots, and the medium accommodating section 10 including the magazine 50 is provided. Has no provisional slot, and in the embodiment shown here, two provisional slots 13 A and 13 B are provided on the recording / reproducing apparatus 30 side as viewed from the medium transfer section 20. .
- the temporary slot may be provided not only in the medium storage unit 10 but also in the medium storage unit and on the recording / reproducing device 30 side.
- the number of provisional slots may be one, but if a plurality of provisional slots are provided, the provisional slots can be properly used so that the movement of the medium transfer section 20 is minimized. It is also possible to take out the MO for which the new M ⁇ ⁇ ⁇ ⁇ ⁇ to be loaded is known in advance from the medium storage unit 10 and place it in the temporary slot in advance, as compared with the case where only one temporary slot is provided. In the above embodiment, the device for accessing the MO has been described.
- the present invention is not limited to the device for the MO, but may be used to access a storage medium other than M ⁇ , such as a magnetic tape.
- the present invention can also be applied to a target device. Further, in the above-described embodiment, an apparatus that performs both recording and reproduction has been described. However, the present invention can be applied to an apparatus that performs only one of recording and reproduction, such as a reproduction-only apparatus.
