A drive system (10, 10A) for rotating a disk (22) includes a housing (28, 28A) having a planar element (12, 12A) with a working surface (14) which includes a spindle (18) which facilitates rotational movement of the disk (22) relative to the drive as- sembly. A plurality of orifices (23) extend through the planar element at an acute angle relative to the working surface (14) and are arranged in a circular array. A conduit assembly (26, 26A) delivers fluid to the housing (28, 28A). The fluid exits through the orifice outlets (24) to provide a motive force for rotating the disk (22) around the spindle (18), while also providing a supporting force to support the medium.
