Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a magnetic head device for a floppy disk drive, and particularly to a magnetic head device for a floppy disk drive. This invention relates to the gimbal structure of the head device.

0002

[Conventional technology]

Conventionally, the magnetic head device of such a floppy disk drive device is as shown in Fig. It is configured as shown in 3.

0003 That is, in FIG. 3, the magnetic head device 1 includes a magnetic head 2 and a magnetic head 2. a gimbal 3 supporting the magnetic head 2, and a flexible terminal base electrically connected to the magnetic head 2. It is composed of a plate 4.

0004 Here, the gimbal 3 has a first movable part 3a that directly supports the magnetic head 2. , a second movable part 3b, an outer frame part 3c, and groove parts 5 and 6. A flexible terminal board 4 extends outward from the outer frame portion 3c.

[0005] In the magnetic head device 1 configured in this way, the first movable portion 3a is A connecting portion formed relatively thinly at both ends of the second movable portion 3b. Since the recording medium (not shown) is connected to the magnetic head device 1 through the The magnetic head 2 that is in contact with the gimbal 3 and supported by the gimbal 3 is the first movable part of the gimbal 3. 3a and the second movable part 3b, the first movable part 3a vibrates. This results in the occurrence of so-called "head noise."

[0006] Therefore, at the edge of the first movable part 3a that is not provided with the connection part, the first movable part 3a As shown in the figure, stick double-sided adhesive tape 7 between the moving part 3a and the second moving part 3b. By doing so, the above-mentioned "head noise" is prevented.

[0007]

[Problem that the idea aims to solve]

However, in the magnetic head device 1 configured in this way, double-sided adhesive As shown in FIG. 4, the tape 7 includes release paper 7b on both sides of the adhesive layer 7a. As mentioned above, the first movable part 3a and the first movable part 3a of the gimbal 3 When pasting between the second movable part 3b, peel off the release paper 7b on both sides in advance, and then I am trying to attach it, but the adhesive side is exposed to the surface when attaching it. Moreover, it was difficult to perform the adhesion work, and there was a problem in terms of workability.

[0008] In view of the above points, the present invention has been developed to provide a head between the first and second movable parts of the gimbal. A magnetic head that makes it easy to apply adhesive tape to prevent squealing. The purpose is to provide a coded device.

[0009]

[Means to solve the problem]

According to the present invention, the above object is to provide a magnetic head and a zipper that supports the magnetic head. and a flexible terminal board electrically connected to the magnetic head. The gimbal includes a first movable part that directly supports the magnetic head, and a first movable part that directly supports the magnetic head. a floppy disk drive having a second moving part coupled to a second moving part; In the magnetic head device, the gimbal has a first moving part and a second moving part. It has a structure in which adhesive tape with a thin protective layer is attached to the surface so that it connects. This is achieved by a magnetic head device characterized by the following.

0010

[Effect]

According to the above configuration, since the protective layer is provided on the surface of the adhesive tape, The adhesive tape itself is constructed as a so-called single-sided adhesive tape, so it is easy to apply. The work can be carried out easily, improving work efficiency and providing a protective layer. Since it is formed thin, it does not come into contact with other parts in the magnetic head device. There is no need to touch the head, just like using traditional double-sided adhesive tape. This means that squealing can be effectively prevented.

[0011]

【Example】

Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

0012 FIG. 1 shows an embodiment of a magnetic head device according to the present invention. The device 10 includes a magnetic head 11, a gimbal 12 that supports the magnetic head 11, and a gimbal 12 that supports the magnetic head 11. It consists of a flexible terminal board 13 that is electrically connected to the magnetic head 11. Ru.

[0013] The gimbal 12 includes a first movable part 12a that directly supports the magnetic head 11; It is formed from a second movable part 12b, an outer frame part 12c, and groove parts 14 and 15. , the flexible terminal board 13 extends outward from the outer frame portion 12c. Ru.

[0014] Furthermore, the magnetic head device 10 is configured to connect the first movable portion 12a of the gimbal 12. Between the first movable part 12a and the second movable part 12b at the edge without a part As shown in the figure, an adhesive tape 16 is attached.

[0015] The above configuration is similar to the conventional magnetic head device 1 shown in FIG. In the magnetic head device 10 according to the present invention, the adhesive tape 16 is as shown in FIG. In addition, a protective layer 16b such as a thin vinyl tape is placed on the surface side of the adhesive layer 16a. A release paper 16c is provided on the back side of the holder.

[0016] The magnetic head device 10 according to the present invention is configured as described above. The first movable part 12a of the cable 12 includes a connecting part to the second movable part 12b. The edge that is not connected to the second movable part 12b via the adhesive tape 16 The second movable portion 12a of the first movable portion 12a is Since the vibration to the movable part 12b is suppressed, so-called "head noise" is reduced. can be prevented.

[0017] Here, the adhesive tape 16 itself is a normal single-sided adhesive tape, as shown in FIG. Since it is formed as a Since the protective layer 16b is formed thinly, the overall thickness of the adhesive tape 16 is Since it is almost the same as the conventional double-sided adhesive tape 7, the surface of the protective layer 16b is protected against other parts. There is no chance of you coming into contact with someone else.

[0018]

[Effect of the idea]

As described above, the present invention provides a gimbal for preventing head noise. The work of pasting the adhesive tape between the first and second movable parts can be easily performed. An extremely excellent magnetic head device can be provided.
