Description

[Detailed Description of the Invention] The present invention relates to the structure of a slide frame that has a recording function by providing a magnetic recording layer on the outer surface of one of a pair of frame pieces that sandwich a slide film.

A slide frame provided with a magnetic recording layer as described above, a so-called slide frame with sound, is extremely convenient to use because the slide film and sound are always accompanied.

However, the magnetic recording layer provided in such a slide frame is
As shown in the figure, since the surface is flat, the contact adjustment of the magnetic gap portion of the magnetic head 2 with respect to the magnetic recording layer 1 is delicate, making it difficult to expect stable audio recording or reproduction operations.

In order to eliminate this obstacle, an elastic layer 3 is provided on the back surface of the magnetic recording layer 1.
However, if only the elastic layer 3 is provided, there is a concern that the planarity of the magnetic recording layer 1 will be impaired through the elastic layer 3 due to etching of the curved film 4 as shown in FIG.

That is, it is affected to some extent by localized and sudden changes in the unevenness of the base.

Moreover, great flexibility often requires careful handling.

The present invention provides a slide frame that has good audio characteristics without the above-mentioned obstacles and is easy to handle.

FIG. 3 shows a part of the basic structure of the present invention, in which a rigid plane serving as the base of the elastic layer 3 is integrated with the elastic layer 3 as a rigid layer 5.

In this structure, as shown in FIG. 3, local unevenness does not affect the magnetic recording layer 1 at all due to the rigid layer 5.

Therefore, as shown in FIG. 4, the present invention employs a multilayer structure that sequentially includes three types of layers: a magnetic recording layer 1, an elastic layer 3, and a rigid layer 5, as one frame piece 6 of the slide frame. The film 4 is placed in the recess 8 in the other frame piece 7 of the slide frame.
One of the frame pieces 6 is fitted from the rigid layer 5 side via the above and fixed by adhesive.

The other frame piece 7 of the slide frame is made from a synthetic resin molded frame or an aluminum plate press molded frame.

In the above explanation, in order to make it easier to understand the concept of the present invention, the elastic layer and the rigid layer were described as if they were separate materials. As a result, it may be made of a single material with elastic properties on one side and rigid properties on the other side.

As mentioned above, in the slide frame with sound of the present invention, the magnetic recording layer maintains the best contact relationship with the magnetic head by its elastic layer, and the rigid layer underlying the elastic layer allows the magnetic recording layer to be This eliminates the concern that the flatness of the recording layer will be impaired.

Further, since this multilayer structure formed as one frame piece of the slide frame has the role of a rigid plate as a whole, it is easy to handle and is useful in the slide frame assembly process.
