Abstract
A housing for an information storage medium where at least one surface of that housing includes a plurality of grooves. A locomotion apparatus to move Applicants' housing within an information storage and retrieval system, where that apparatus includes at least one rotatable shaft and at least one drive member disposed on that shaft, where each such drive member has the shape of a truncated cone, and where each such drive member includes a drive surface which includes a plurality of ribs. Applicants' drive member contacts the grooved surface of Applicants' housing such that one or more of the ribs disposed on the drive surface intermeshes with one or more of the grooves in the housing. Rotation of the rotatable shaft in a first direction causes the housing the move in a second direction. Rotation of the rotatable shaft in a third direction causes the housing to move in a fourth direction.
