The present invention provides a recordingreproduction apparatus which can record AV data at a variable rate as well as so as to enable trick plays. Inserting a wider and thicker card, the card engages and moves together with the slider into the housing to contact contacts on one surface in the housing at a predetermined inserted position. The alignment notch has opposing edges wherein at least a portion of the opposing edges is in substantially parallel relation to the longitudinal axis. A second, traveling mode automatically locks the rear wheel steering system allowing vehicle to be driven at a speed of up to 20 kmh, all being computer controlled.
