ABSTRACT:
The invention relates to a video cassette comprising two spools with single disk, the respective hubs of which spools are rotatably mounted with the minimum distance possible between their axes of rotation, inside a casing in two parts, so that the said disks partly overlap in projection and are contiguous respectively to the bases of the said casing parts, each base being provided, opposite the disk which it does not touch, with at least one zone projecting in extra thickness from the base in question so that its fixed guiding surface for the magnetic tape extends in the same plane as the internal annular face of the adjacent rotary disk, the said surface being anti-abrasive and entirely slippery, cassette wherein each of said zones is constituted by an independent part molded in self-lubricating and anti-abrasive plastic material, the said part being added on to the corresponding base of the casing and being fixed thereon by non-deformable securing means.
According to the invention, each projecting zone is constituted by an independent part, molded from self-lubricating and antiabrasive plastic material, the said part being added on to the corresponding casing base and fixed thereon by non-deformable fastening means.
