PURPOSE:To omit the solderling process and to facilitate an easy exchange of a rotary head disk by securing the ON/OFF control of the contact and conduction between the 1st conduction member for the winding of a rotary transformer of the rotary side and the 2nd conduction member for the winding of a magnetic head just by attaching and detaching a pressure member. CONSTITUTION:A base 11 is welded to a rotary drum 2, and the conduction is secured between a head lead wire 8 and a plate type conduction member 10. The inside face of the drum 2 is set with a proper gap to a terminal pin 7 of the member 10 when the drum 2 is put on a disk 4. Then the inside face of the drum has a contact with the pin 7. A pressure member 12 is attached so that a projection part 13 holds the member 10 from the upper side of the drum 2 with the drum 4 kept on the disk 4. In this case, the member 12 can be attached smoothly since the projection 13 has a curve part. |
