Next, the disc carrier 9 holding the disc cartridge is moved in front of the recording/reproducing apparatus 3, and the disc cartridge 1 is inserted into the recording/reproducing apparatus by the insertion/ejection device 12. Note that by rotating the disc carrier 9 180 degrees in the direction shown by arrow C before inserting the disc cartridge, recording and reproduction can be selectively performed on both recording surfaces of the disc.

Through the above-described operations, the disk cartridge 1 is automatically exchanged with respect to the storage case 2 and the recording/reproducing device 3.

Problems to be Solved by the Invention However, with this configuration, in order to replace a disc, it takes time to move the disc carrier to a predetermined position in the storage case, and time to insert and remove the disc cartridge from the storage case to the disc carrier. However, there is a problem in that it requires time to move the disc carrier to the recording/reproducing apparatus and time to insert/remove the disc cartridge from/to the recording/reproducing apparatus, which increases the time required to replace the disc.

In particular, as the number of discs stored in the storage case increases, the time required to move the disc carrier from a predetermined slot in the storage case to the recording/reproducing device becomes longer, and the time required for replacing discs becomes longer.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide an automatic disk exchange device that can quickly exchange disks while using a storage case that stores a large number of disks. .

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention does not use a conventional disc carrier, but instead uses a disc carrier that faces the slot of the storage case housing the disc car 1-1. The storage case and the recording and reproducing device are arranged so that the reproducing device is arranged and the storage case and the recording and reproducing device are simultaneously moved in opposite directions so that the recording and reproducing device moves relatively along the storage case.

Effect of the Invention With the above-described configuration, the present invention allows the recording and reproducing device to be positioned directly opposite a desired slot of the storage case when replacing a disk, and the disk can be directly inserted and removed between the storage case and the recording and reproducing device. , disk replacement time can be shortened. Furthermore, when moving the recording/playback device to a predetermined slot in the storage case, not only the storage case is moved as well as the recording/playback device, so the relative speed between the two is approximately doubled, and from this point of view, it also takes longer to replace the disk. can be shortened.

EXAMPLE Hereinafter, an example of the present invention will be described based on the accompanying drawings. In FIG. 1, numeral 21 is a disk cartridge rotatably containing a double-sided disk having recording surfaces on both sides. ρ is a storage case that includes a plurality of disk cartridges 22a for storing the disk cartridges 21 in an array. A groove 22b for inserting and removing a disk is formed on the upper surface of the storage case B, corresponding to each slot 22a. This storage case is held by a guide shaft extending perpendicularly to an internal slot 22a and a ball screw holder.
It can be moved in the direction of the arrow by rotating 4. 5 is
