ABSTRACT:
Disclosed is optical data signal apparatus for optically coupling a plurality of data channels between stationary and rotating systems. The optical data signal apparatus is useful in a rotary head scanner for coupling a plurality of data channels between a rotating head wheel, having a plurality of magnetic record/reproduce heads, and stationary signal processing circuitry. Each data channel of the apparatus includes an optical data signal transmitter, an optical data signal receiver and an optical coupling element for causing an optical data signal transmitted by the transmitter to be focused on the receiver. The plurality of optical coupling elements are preferably annular and arranged concentrically in a plane. Each optical coupling element focuses the optical data from a transmitter to a respective receiver which is positioned off axis with respect to the central axis of the concentric optical elements. Preferably the optical elements are holographic optical elements.
