ABSTRACT:
A flexible information storage disc includes a central mounting portion and an outer body portion providing a surface area on which information may be recorded. The central mounting portion is provided with a least first and second apertures disposed radially outwardly with respect to the geometric center of the disc. The first and second apertures are respectively arcuately elongated in directions conforming to rotation of the disc about its geometric center. The leading end of the first aperture is defined by a pair of straight edges angularly intersecting at an apex and the leading end of the second aperture is defined by a single straight edge. The pair of intersecting straight edges of the central mounting portion bounding the leading end of the first aperture and the single straight edge of the central mounting portion bounding the leading end of the second aperture cooperate to provide three abutment edges arranged in respectively different planes normal to the disc for precisely locating the disc both radially and angularly.
