Abstract

PURPOSE:To reduce cost by simplfying assembly and reducing the number of parts by fixing a motor rotor together with the rotor side core of a rotary transformer to the upside drum of a head drum. CONSTITUTION:A motor rotor 1a of a motor 1 is fitted through fitting boss 12 to an upside drum 7 by a screw 15, and a rotor side core 10 of a rotary transformer 9 is also fitted through an interruption connector 17 to the drum 7 together with the rotor 1a similarly by the screw 15. On the other hand, a motor stator 1b of the motor 1 is fitted to a downside drum 4 by a screw 16 and on the other hand, a stator side core 11 of the transformer 9 is fitted as well. The drum 7 is fitted to a disk 5 by a screw 8 and in the case of recording and reproducing, input/output signals are transmitted by the transformer 9 between the drum 7 to be rotated by the motor 1 and a drum 4 at a non- rotary part. Thus, the cost can be reduced by simplifying the assembly of the head drum and reducing the number of parts.

Further, the rotor-side core 10 of the rotary transformer 9 is similarly attached to the upper drum 7 with screws 14 via a relay coil 131. Therefore, the motor rotor 1a of the motor 1 and the rotor-side core 10 of the rotary transformer 9 are directly attached to the upper drum 7. Further, the motor stator 1b of the motor 1 is attached to the lower drum 4 with screws 16, and the rotary shaft 2 projects upward through a bearing 3, and a disc 5 is provided at the upper end. The stator side core 11 of the rotary transformer 9 is mounted on the lower drum 4.
The installation is also damaged. A magnetic head 6 is also attached to the upper drum 7, and the magnetic head 6 and the loader-side core 10 of the rotary transformer 9 are connected via a relay connector 13. (The rotor-side core 10 and the relay connector 13 are bonded together.) Also, the upper drum 7 is attached to the disk 5 by screws 8, and with this configuration, the upper drum 7 rotated by the motor 1 and the A rotary transformer 9 transmits input/output signals to and from the lower drum 4 of the rotating section.
