PURPOSE:To increase the density of a disc, by providing a sectioning member separating discs and forming at least the surface of the sectioning member in contact with the disc with a type of material equal to or softer that on the disc surface. CONSTITUTION:At a disc containing section 32, discs 2 are contained by being clipped between two sectioning plates 35 to reduce the friction due to torsion of the disc sectioning plates at disc movement and avoid damages to the discs 2 with almost I shape having a guide wall 38, and at least surface treatment such as ''Teflon '' coating is applied on the surface of contact section with the discs 2. Further, in the plate 35 the front and back parts of the guide wall 38 have taper or curved shape to make the loading of the discs 2 easy and as a guide to return the disc 2 from the playing position to the contained position. |
