Abstract: A data recorder/reproducer device for disc media, particularly limply flexible magnetic disc media, having a pair of door-like structures mounted on opposite sides of a supportive frame, each such structure defining a narrow slit-space for receiving a recording disc and its envelope and mounting the same for recording, with a drive shaft supported on the frame centrally thereof, having a drive hub at either end aligned with the central opening in the recording disc, such that both discs are driven by the same drive train. The device has at least two recording heads, one for each disc, and the heads are articulated for selective control of movement toward or away from their particular disc, into or out of transducing relation thereto; also, the heads are mounted for translational movement across the face of their respective discs, generally radially thereof. In a preferred embodiment, there are four such heads, one for each side of each disc, so that all four sides may be recorded in a selective manner, each such head being movably articulated.
