    A magnetic disc cartridge, having a jacket which contains a rotatable magnetic disc, is loaded into a cartridge holder of recording and/or reproducing apparatus for recording and/or reproducing signals on the rotatable magnetic disc. The cartridge has a guide groove longitudinally extending in a direction in which the cartridge is inserted into the holder for receiving a guide element provided in the holder. A shutter is movable across a window provided in the jacket between a closed position and an opened position, and includes a projection extending into the guide groove to be contacted by the guide element when the cartridge is inserted properly into the holder. The guide element thus moves the shutter is from the closed position to the open position thereof when the cartridge is inserted in the cartridge holder.

    The invention relates to the field of information storage, in particular to recording-reproducing devices on a floppy disk. A device for recording on a flexible magnetic disk is known comprising a shaft on which a flexible magnetic disk is fixed. This device provides rotation of a flexible magnetic disk in the process of recording and reproducing L. A disadvantage of the known device consists in the considerable complexity of its maintenance. It is also known a recording-reproduction device on a flexible magnetic disk comprising a rotary cover made with guide grooves in which a box-shaped casing is installed, between the side walls of which there is a flexible magnetic disk mounted on a shaft placed in the round holes of the case cheeks roll cover, one of which is provided with an inlet. This device allows for relative simplicity of its maintenance. 2J. The disadvantage of such a device is the possibility of damaging a flexible magnetic disk, which is caused by the difficulty of combining the simplicity of maintenance and reliable protection of a flexible magnetic disk. The purpose of the invention is to reduce the possibility of damage to a flexible magnetic disk. The goal is achieved due to the fact that in a recording device, a.-Reproduction on a flexible magnetic disk, containing a rotary knob, filled with guide grooves, in which a shell-shaped casing is installed, between the side walls of which a flexible magnetic disk is mounted on the shaft, placed In the round openings of the cheeks of the case-like casing, one of which is made with an inlet, a damper is inserted against the inlet-opening with the possibility of opening and provided with pins and a sliding plate. There is an astina with a protrusion tension spring, one end of which is connected to the housing casing, and a rope, reinforced between the cheeks of the casing, is made with 1 mi and grooved guides and. and one of the side-walls of the housing casing is made with a guide slot, the damper pins being installed in the guide grooves of the cheeks of the casing with movement so that they can move in them, and one of the guide slots of the swivel cover is provided with a stop lug mounted to move the damper the impact on the protrusion of its sliding plate connected to the other end of the tension spring connected to the roller. The proposed device, by inserting a damper installed against the inlet opening with the possibility of opening it, an extension spring and a roller, greatly reduces the possibility of damage to the flexible magnetic disk. FIG. 1 shows the arrangement of a rotatable cover in one of the embodiments of the burner for recording and reproducing on a floppy disk; in fig. 2 - FIG. 4 different types of leather cover. The proposed device comprises a rotary cover 1 made with guide slots 2 in which a shell-like casing 3 is installed. Between the side walls of the case-shaped casing 3 there is a flexible magnetic disk 4 fixed to the hollow shaft 5. At the same time, the shaft 5 is housed in circular apertures 6 jaws 7 of the case body 3, one of which is provided with an inlet 8. The proposed device also contains a flap 9 mounted against the inlet 8 with the possibility of opening and fitted with pins 10 and a sliding plate another 11, made with a protrusion 12, a stretch spring 13, one end of which is connected to the case-like casing 3, and a roller 14. The roller 14 is reinforced between the cheeks 7 of the case-shaped case 3, made with guide grooves 15. One of the lateral The walls of the casing-shaped casing 3 are made with a guide slot 16. The pins 1b of the shutter 9 are installed in the guiding grooves 15 of the cheeks 7 of the casing-shaped casing 3 so that they can move in them. Here, the sliding plate 11 is connected to the other end of the tension spring 13, which is mated to the roller 14.
    One of the guide grooves 2 of the rotatable cover 1 is provided with a stubbornly high stupid 16 mounted to move the shutter 9 when the protrusion 12 of the sliding plate 11 is exposed. The rotary cover 1 is mounted on the base
    17, which hosts the drive shaft
    18 assembled to mate with the shaft 5 of a flexible magnetic disk 4.
    Recording - playback on a floppy disk using the proposed device is as follows.
    Before recording or reproducing, the case-like casing 3 is pushed into the slots 2 of the pivoting cover 1. The thrust protrusion 16 acts on the protrusion 12 of the sliding plate 11, which moves to overcome the resistance of the extension spring 13. As a result, the shutter 9 is also moved, opening the inlet 8.
    After installing the case-like casing 3 in the grooves 2, the rotary cover 1 is pressed against the base 17, which mates the drive shaft 18 with the shaft 5 of the flexible magnetic disk 4 and inserts the magnetic head into the inlet 8. The magnetic head moves radially relative to the flexible magnetic disk 4 driven by the drive shaft 18.
    After the recording or playback has been completed, the case-like casing 3 is pulled out of the slots 2 of the rotary cam 1. The flap 9 closes the inlet 8, ensuring reliable protection of the flexible magnetic disk 4.
    The use of the invention in comparison with the base object allows a considerable reduction in the possibility of damage to the flexible magnetic disk.
