    The invention relates to the accumulation of information, namely, the recording and reproduction of optical information on a flexible medium, and can be used in the design of protecting from damage flexible disk storage media cassettes. A known cassette for a flexible disk medium containing an envelope and a screen enclosed in it, allowing them to be taken out of the envelope and receiving disk information carrier 1 onto its circular cavity. The disadvantage of this cassette is not sufficiently accurate centering of the disk and playback. Also known is a cassette for a flexible information carrier containing an envelope with a hole and a rectangular screen located in the envelope with a cavity on its working surface. Keeping the disc in such a cassette exactly in the center is provided by the interaction of magnets embedded in the screen material and disc carrier 2. However, this design requires a complex technology of placing magnets in the disc and screen material and, moreover, the known cassette does not allow for recording disk media in the case of two-way recording The purpose of the invention is to reduce the surface of contact between the screen and the flexible information carrier. This goal is achieved by the fact that in a cassette for a flexible information carrier containing an envelope with a hole and a rectangular screen located in an envelope with a cavity on its working surface, the screen cavity is made circular with an annular concentric cutout at the bottom with conical side surfaces, and one The inner surfaces of the envelope are made with a cutout that is symmetrical to the cavities of the screen, the envelope is provided with grooves, and the screen is guided on its side surfaces. In addition, the screen from the side of the hole of the envelope is made with a protrusion in height equal to the thickness of the envelope. In order to provide the possibility of stacking several cassettes during their storage, the outer surfaces of the jacket are made with bosses and heights. FIG. I shows the envelope; in fig. 2 — screen inserted into the envelope; Fig. 3 shows a section of an envelope with a screen and a disc in it; in fig. 4 - part of the screen in cross section ;, in FIG. 5 shows a screen interface with an envelope on the side surfaces; in fig. 6 — possibility of stacking multiple cassettes. The screen 1 has the shape of a rectangular plate (Fig. 2), having a protrusion 2 on the side of the screen, resting against the open end of the envelope when the screen is inserted into it. The opposite side 3 of the screen can be made with bevels for easy insertion of the screen into the envelope. A cavity 4 is provided on the working side of the screen to locate a disk in it. The depth of the cavity can be chosen depending on the thickness of the disk, flexible or hard. At the bottom of the cavity. 4, a cutout 5 is made in the form of a ring, the diameters of which are determined by the diameters of the beginning and end of the recording on the disc. The lateral surfaces of the cavity are made conical b) 7 so as to avoid scratching the disks with the sharp edges of the cavity- (Fig. 4). The inside surface 8 of the envelope (FIG. 3) is made with a symmetrical profile of the cavity 4 of the screen I for fixing the disk when the envelope is rotated in space. The envelope and the screen have correspondingly guiding grooves 9 and arches 10 (Fig. 5). The outer surfaces of the envelope have bosses 11 and sockets 12 to enable stacking (Fig. 2). The interaction of the elements of the cassette is as follows. While the cartridge is being loaded with a disk, the screen slides along the envelope guide grooves. A disk is placed in the cavity, which is centered by conical surfaces. When placing a screen with a disc in an envelope, the protrusion of the screen covers the envelope opening, and thus the disc is protected from dust particles and damage. At any orientation of the cassette in space, the disk located between the screen and one of the inner surfaces of the envelope is paired with the latter only parts with an unrecorded area, which saves the disk medium. For playback, a disc cassette is inserted into a slot of a playback device (not shown) and the device mechanism pulls a disc screen out of the envelope. The cassette thickness is increased and the screen is removed. The proposed cassette allows you to protect the deck from damage on its two sides. The cassette provides tightness of the internal cavity.
