ABSTRACT:
Information is recorded and/or read on the upper major surface of a flexible information storage disc. The disc is contained within a housing to provide a cartridge or cassette, the housing protecting the recording surface of the disc. The housing includes an opening for receiving a rotational means coupled to a body having a cylindrical surface. The flexible disc is rotated over the cylindrical surface with the lower major surface of such disc facing the cylindrical surface so that rotation of the disc causes the disc to conform to the curvature of the body. An opening is provided in the housing exposing a portion of the upper major surface of the disc so that a recording and/or playback head is selectively passed over the recording surface of the disc for reading and/or writing information on the disc as it rotates.
