Abstract
A data recorder/reproducer device for flexible magnetic disc media, having a door-like structure mounted on a supportive frame. The door structure receives a recording disc and is adapted to carry a recording head at one or both sides of the disc. The heads are articulated for selective control of movement toward or away from the disc, into or out of transducing relation and also for translational movement across the face of the disc, generally radially thereof. The device includes novel interlocking actuator means which prevent opening of the door or doors except when the heads, positioned by a translational drive means, are in a predetermined "home" or start position at the edge of the disc, thereby preventing the inadvertent erasure or other loss or destruction of the recorded information.
