Abstract

PURPOSE:To realize not only a thin-gage and flat structure but the high inspection/ exchange properties of a motor for a tape travel guiding medium, by installing a head and a rotary transformer between the upper and lower bearings of a rotary head drum shaft plus a shaft rotation driving motor at the lower part of the drum shaft, respectively. CONSTITUTION:A rotary disk 3 and a rotary head drum 1 which are fixed to a shaft 4 are provided on the upper surface of a lower cylinder tape guiding medium 2. On the lower surface of the drum 1, a head 6 is fixed with a screw at the middle position between upper and lower bearings 5a and 5b of the shaft 4, and rotary transformers 7 and 8 are provided on the upper surface between the inner circumference of a tape guiding surface 2a of the medium 2 and the outer circumference of a bearing housing 20. A motor consisting of a magnet rotor 11 at the lower part of a plate 10 fixed by a boss 14 plus a 3-phase coil 12 and a stator 13 is provided at the lower part of the shaft 4. The magnetic flux of a rotor 11 is detected through a position detecting hole 15 attached to a motor housing 9 in order to perform the exchange of the coil 12.
