Regarding the collective recording and reproducing device configured as above,
The operation will be explained below with reference to the operation flowchart in FIG.

The cartridge carrier 29 is activated by an external signal.
It is positioned at a desired position relative to the storage case 26 by the motor 33 and ball screw 32. Next, with the tip of the engaging claw 42 of the insertion/removal means 38 being horizontal so that it can be inserted into the engaging portion 25A of the disk cartridge 25, the ball screw 40 rotates and the support member 41 moves forward in the direction of the arrow. , the engaging claw 42 is connected to the engaging portion 2 of the disk cartridge 25.
It is inserted into 5A. Next, the engaging pawl 42 is rotated by 90 degrees by the motor 43, and the engaging pawl 42 engages with the engaging portion 25A. Thereafter, by reverse rotation of the ball screw 40, the engagement pawl 42 moves in the direction opposite to the direction of arrow A, pulls out the disk cartridge 25'i from the storage case 26, and moves it into the cartridge carrier 29. The cartridge carrier 29 holding the disk cartridge 25 is moved in the direction of arrow B by a motor 33 and a ball screw 32.
It is positioned in front of the recording/reproducing device 27a or 27b.

At this time, if necessary, the cartridge carrier 29 is rotated 180 degrees in the direction of arrow C by the motor 36 and pulley 35 to position the desired recording surface of the disk. Thereafter, the insertion/removal means 38 operates in the opposite manner to the above, and the disk cartridge 25 in the cartridge carrier 29 is installed in the recording/reproducing apparatus.

In FIG. 2, the disk cartridge 25, which has been loaded into the recording/reproducing apparatus by the insertion/removal means 38, is moved by the loading mechanism from the position shown by the two-dot chain line to the position shown by the solid line, and the disk 45 is clamped to the turntable 46. After that, the optical head 48 moves in the radial direction of the disk 45, and the sensor 51 measures the dirt on the recording/reproducing surface of the disk in the disk radial direction, and compares the dirt with a predetermined standard. If it is within the range, recording or reproduction is performed using the optical head 48. After recording or reproduction, the insertion/removal means 3
8, the disc cartridge 25 is taken out from the recording/reproducing apparatus into the cartridge recording/reproducing apparatus 29, carried to a predetermined position in the storage case 26, and returned.

If the dirt measured by the sensor 51 is outside the standard, no recording or reproduction is performed, and the disk cartridge 25 is returned to the position indicated by the two-dot chain line by the loading mechanism, and then taken out from the recording and reproduction apparatus by the insertion/removal means 38 and placed in the cartridge carrier 25. and transported to the disk cleaning device 28 by the cartridge carrier 29. Thereafter, the disk cartridge 25 is installed in the disk cleaning device 28 by the insertion/removal means 38.

In FIG. 3, the disc cartridge 25 inserted into the disc cleaning device 28 at the position indicated by the two-dot chain line is
The disk 45 is moved to the solid line position by the loading mechanism, the disk 45 is clamped to the turntable 53, and the cleaning surface of the brush 55 comes into contact with the disk recording surface. after that,
The disk 45 is rotated by the motor 54, and the recording surface is cleaned by the brush 55 to remove dirt. The cleaned disk cartridge is inserted into the insertion/removal means 38.
is taken out into the cartridge carrier 29, sent to the recording and reproducing device again, and mounted therein. In this way, recording and playback can be performed with the disc clean.

As described above, the storage case 26, the recording/reproducing device 27
a, 27b 1 The disk cartridge is automatically exchanged between the disk cleaning devices 28, and normal recording or playback is performed with the disk clean.

In the above embodiment, the dirt on the disc is measured using a senna, and only the discs with dirt exceeding the standard value are installed in the disc cleaning device and cleaned. Don't do it,
After a certain period of use, all the disc cartridges may be sequentially sent to a disc cleaning device for cleaning. In addition, a reference disk is stored in the storage case, and this reference disk is sent to the recording/playback device at a certain period to be read.The error rate at that time is detected, and when the error rate exceeds a predetermined value, all disks are may be sequentially sent to a five-disk cleaning device for cleaning.

Effects of the Invention As is clear from the above description, the present invention is a collective type recording and reproducing device that includes a disk storage case and a recording and reproducing device, and further provides a method for removing dirt from the disks stored in the disk cartridge. By providing a disc cleaning device and making it possible to supply and eject discs to and from the disc cleaning device, the discs in the storage case or the recording/playback device can be supplied to the disc cleaning device and cleaned at an appropriate time. After that, the disc can be returned to the storage case or the recording/reproducing device, and the effect is that normal recording/reproduction can always be performed.
