Abstract

(57) [Abstract] [Object] The present invention relates to a magnetic head device for a floppy disk drive, and it is an object of the present invention to provide a thin head device by eliminating protrusions of soldering portions of terminals of a head element. . A magnetic head device 10 for a floppy disk drive comprises a gimbal 11, a flexible printed circuit board 12 fixed to the gimbal, and a head element 13 electrically conductively fixed to the flexible printed circuit board. The magnetic head device 10 has a structure in which a protrusion including the head element is formed only on 11a and no protrusion is formed on the other surface 11b.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a floppy disk drive device as a storage device such as a computer and a word processor, and more particularly to the structure of its magnetic head.

[0002]

[Prior art]

 An example of a conventional magnetic head for a floppy disk drive is shown in a schematic side view of a main part of FIG. 2. The description will be made about a conventional magnetic head 1 including a gimbal 2 and a head 2a on one surface 2a of the gimbal 2. The element 3 is fixed, the flexible printed circuit board 5 is electrically connected to the head terminal 4 of the head element 3 protruding through the gimbal 2 on the other surface 2b, and the element 3 is bonded to the one surface 2b of the gimbal 2. It is said that.

[0003]

[Problems to be solved by the device]

 However, in the above-described conventional floppy disk magnetic head 1, the head terminals 4 of the head element 3 are soldered in a state of protruding from the flexible printed circuit board 5 adhered to the one surface 2b of the gimbal 2.

Therefore, when thinning the floppy disk drive device, the protrusion of the head terminal 4 due to soldering has a great influence when the size of the head portion in the height direction is reduced as much as possible. However, in order to keep the height of the head device 1 low, there has been a problem that it is necessary to reduce the protrusion of the head terminal 4 due to soldering.

The present invention has been devised in view of the above problems, and an object of the present invention is to provide a magnetic head device in which the dimension of the head device in the height direction is reduced.

[0006]

[Means for Solving the Problems] As a means for solving the above problems, the present invention provides a magnetic head for a floppy disk drive, wherein the magnetic head is a gimbal and a flexible member fixed to the gimbal. It is composed of a printed circuit board and a head element conductively fixed to the flexible printed circuit board, and is characterized in that the head element is fixed to only one surface of the gimbal through the flexible printed circuit board.

[0007]

[Action]

 The head element is arranged only on one surface of the gimbal through the flexible printed circuit board, and the head terminal of the head element is soldered only on one surface side of the gimbal without protruding to the other surface side. The head device is made thinner.

[0008]

【Example】

 Hereinafter, as an embodiment of the present invention, an embodiment of the magnetic head device according to the present invention shown in the schematic side view of the essential part of FIG. 1 will be described.

As shown in the figure, in the magnetic head device 10 for a floppy disk according to the present invention, a flexible printed circuit board 12 is adhered only to one surface 11 a of the gimbal 11, and electrode terminals of the head element 13 are attached via the flexible printed circuit board 12. The head 13 is soldered so that the surface 13a is a flat mounting means by cream solder, or the head terminal is soldered so that the size of the thickness of the gimbal 11 and the thickness of the flexible printed circuit board 12 are within the range of arrow B in the figure. The total height of is within the range indicated by arrow A in the figure.

Here, the head device 10 has a structure in which the protrusion including the head element 13 is formed only on one surface 11 a of the gimbal 11 and no protrusion is formed on the other surface 11 b. The height dimension will be considered as a major factor in thinning.

[0011]

Therefore, according to the magnetic head device for a floppy disk drive according to the present invention having the above-described structure, the head device has the protruding portion formed only on one surface of the gimbal and has no protruding portion on the other surface. With the structure that does not exist, the height direction dimension of the head device can be made thin by setting the dimension in consideration of the height of the head element, and by making the head device thin, At the same time, there is an effect that the floppy disk drive device can be made thinner.
