Abstract: A head drum assembly for a tape recorder maintains a substantially constant preload and reduces manufacturing costs. The head drum assembly includes a shaft fixed to a center of a stationary drum, a rotary drum installed to an upper portion of the stationary drum to be rotated by the shaft and having a rotor, a stator installed to an upper portion of the rotary drum to face the rotor, a bearing interposed between the shaft and the rotary drum that rotatably supports the rotary drum, a spring resiliently supporting an inner race of the bearing, and a drum cover fixed with the stator and fixed to the shaft to apply a substantially constant pressure to the bearing and to substantially constantly maintain a spacing between the stator and the rotor.
Abstract: A head drum assembly for a tape recorder includes a stationary drum fixed on a main base of a deck and having a through-hole formed in the bottom thereof, and a rotary drum having a magnetic head and rotatably installed on the stationary drum by a rotation shaft. A flexible printed circuit is electrically connected to rotary transformers respectively installed in the rotary drum and the stationary drum, for transmitting an information signal read by the magnetic head to a main printed circuit board (PCB). A first connector is coupled to an end of the flexible printed circuit for electrically connecting the flexible printed circuit to the main PCB. The flexible printed circuit is drawn out directly downward via the through-hole so that the first connector is electrically connected to a second connector mounted to the main PCB.

Abstract: A magnetic head device has a wiring board on which are formed first electrode pads connected to a head chip through lead wires and second electrode pads electrically connected to the first electrode pads and arranged for external connection. The lead wires connected to the first electrode pads are covered with an insulating resin. An aperture is formed in the wiring board so as to lie between the first electrode pads and the second electrode pads.
