ヘッド５が同時に安定接触する様になっている。In FIG. 1, when the drive spindle 3 rotates, the clamp hub 2 and the flexible medium 1 held by the drive spindle 3 rotate. The flexible medium 1 is sandwiched between the heads 4 and 5. In the conventional example, generally, the medium contact surface of the lower head 4 is fixed to the carriage 6 so as to be parallel to the medium rotation surface. The upper head 5 is the lower head 4
When the flexible medium 1 is sandwiched between the lower head 4 and the load, the flexible medium 1 and the lower head 4, the flexible medium 1 and the upper head 5 are simultaneously stabilized. It comes in contact.

A frictional force acts between the head and the heads 4 and 5, and slack occurs at the portion where the flexible medium 1 is introduced into the head. This phenomenon will be described with reference to FIG. 2 by taking the case of only the lower head 4 as an example. Due to the contact friction between the flexible medium 1 and the lower head 4, the introduction portion of the flexible medium 1 into the head is slackened, and at the same time, the medium on the head contact surface of the head 4 is deformed so as to be separated. In the conventional double-sided head, as shown in FIG. 3, by forcibly suppressing the deformation by the upper head 5, the flexible medium 1 is stably contacted with the upper head 5 and the flexible medium 1, so that the head contact The deformation of the flexible medium 1 on the surface is
As a result of reducing the load force of the upper head 5, a larger load is required for stable contact, the force locally applied to the flexible medium 1 increases, and the flexible medium 1
It had a drawback that there was a great possibility of scratching the. Further, there is a drawback that the relative positional relationship between the flexible medium 1 and the upper head 5 and the lower head 4 is sensitive to stable contact.

Even when the flexible medium is sandwiched by the head and the medium introduction portion to the head is deformed due to friction, the head load is not increased and is stable. An object of the present invention is to provide a flexible disk drive device that can be contacted with each other and does not require relative positional accuracy between the head and the medium.

媒体回転面に対し角度θを持つことになる。Description of Embodiments A configuration of an embodiment of the present invention will be described below with reference to the drawings. In FIG. 4, reference numeral 1 denotes a rotating flexible medium, and the flexible medium 1 is sandwiched by a lower head 4 and an upper head 5 and slid.
The lower head 4 is held by the carriage 6. The upper head 5 is held by the arm 7. The lower head 4 and the carriage 6, and the upper head 5 and the arm 7 are integrally movable and are track-positioned along the guide lot 8. The guide rod 8 is fixed to the mounting surface 10 of the drive base 9 ′ having the mounting surface 10 at an angle θ (0 <θ <10 degrees) with respect to the medium rotation surface by the metal fitting 11 and the screw 12. After all, the head sliding surfaces of the lower head 4 and the upper head 5 have an angle θ with respect to the medium rotation surface.

る利点を有する。The operation of this embodiment will be described. When the lower head 4 and the flexible medium 1 slide, a slack is generated in the portion where the flexible medium 1 is introduced into the head due to frictional resistance.
There is a tendency for convex deformation on the head surface. In the present embodiment, the head sliding surface has an angle with respect to the rotating surface of the flexible medium 1. Therefore, there is an advantage in that the head and the flexible medium are brought into stable contact with the deformation of the medium. .
