PURPOSE: A trans coil fixing architecture of a magnetic recording reproduction apparatus head drum device is provided to wind intermediate portions of trans coils that transmit a signal between a rotative trans portion and a rotative head, around coil fixing grooves, to fix the trans coils, without extending the trans coils between the rotative trans portion and the rotative head, thereby preventing an interference with a flexible cable of a lower drum. CONSTITUTION: The first coil fixing grooves and the second coil fixing grooves are formed on an outer circumference and a top surface of a head portion of a fixing screw(27) for fixing a rotative head(26) to an upper drum(24). The second coil fixing grooves are crossed at predetermined angle in plural. Trans coils incoming from each channel of a rotative trans portion(40) are wound around the coil fixing grooves, and are soldered in a land portion of the rotative head(26).
