Abstract:
A flexible recording system comprising:a recording disk having a disk-shaped recording medium and a recording medium cartridge rotatably housing said recording medium therein; and a flexible disk drive comprising: a recording medium drive motor driving rotation of said recording medium around a rotation axis; wherein said recording disk further has a hub to which said recording medium is fixedly secured, said hub being movable in an axial direction perpendicular to a bottom surface of said recording medium cartridge, said bottom surface defining a bottom plane of said recording medium cartridge that is orthogonal to said rotation axis, said recording medium cartridge has an opening in said bottom surface through which a surface of said hub protrudes outwardly from said recording medium cartridge upon downward movement of said recording medium in said axial direction, and said recording medium drive motor has an element that attracts said hub of said recording disk, said recording medium drive motor rotating said recording medium while holding said surface of said hub outwardly from said opening of said recording medium cartridge and below said bottom plane such that a non-cross-sectional, side view of said recording medium cartridge during rotation of said recording medium by said drive motor reveals at least a portion of said hub as being exposed from said recording medium cartridge.
