Abstract

PURPOSE:To prevent the distance between a recording medium and a magnetic core from increasing by composing the magnetic head of a magnetic core, elastic members, and sliders and fixing neither the elastic members nor the sliders to the magnetic core. CONSTITUTION:Support columns 2 and 3 which are sectioned in an L shape are fixed on both the flanks of the magnetic core 1 of the slider part 8 of the magnetic head, elastic members 6 and 7 which are made of rubber, etc., are provided on the surfaces of the columns 2 and 3 on the sides of the reocrding medium 9, and the sliders 4 and 5 are fitted thereto. Consequently, even if the sliders 4 and 5 slant to the medium owing to an error in working accuracy, the elastic members 6 and 7 are compressed and the core 1 comes close to the medium 9 by the compression, so stable recording and reproduction are performed without any increase in the distance between the medium 9 and magnetic core 1.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a magnetic head, and particularly to a magnetic head used in a floppy disk device.

[Prior Art] Conventionally, as shown in FIG. 4, a magnetic head used in a floppy disk device has a structure in which a flexible flat medium 9 is sandwiched between a pair of slider parts 10 and 11. There is. The slider portion 10 is mounted on a plate spring 12, and the plate spring 12 is fixed to a base 13. Also, a load arm 1 that holds the slider part 11 is provided.
4, the plate-shaped metal member 15 integrated with this is the presser plate 1.
The medium 9 is fixed to the base 13 by being screwed to the base 13 through the screws 6, and pressure is applied to the medium 9 by applying pressure from a load spring 17. Also,
Conventionally, the slider part 10 is constructed by fixing sliders 18 and 19 having surfaces slidable on the medium 9 on both sides of the magnetic core 1, as shown in FIG.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional magnetic head, variations in the machining accuracy of the sliders 18 and 19 and the plate spring 1
Due to the bending or warping of the magnetic core 2, a part of the slider 10 is tilted, and as shown in FIG. .

Therefore, an object of the present invention is to prevent the distance between the medium and the magnetic core from increasing even if a portion of the slider is tilted.

[Means for Solving the Problems] The technical means of the present invention for solving the above problems is to provide a magnetic head equipped with a magnetic core facing a medium, and a support that fixedly supports the side surface of the magnetic core. , an elastic member fixed to the medium side surface of the support column and not in contact with the magnetic core, and a slider having a sliding surface with the medium and fixed to the elastic member and not in contact with the magnetic core and the support column. It is prepared.

[Example] Next, a magnetic head according to an example of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of essential parts of a magnetic head according to an embodiment of the present invention, and FIG. 2 is an enlarged view taken in the direction of the X arrow in FIG.

As described above, this magnetic head has a structure in which the medium 9 is sandwiched between the slider part 8 and the slider part 11. In the embodiment, the slider part 8 comprises a magnetic core 1 facing the medium 9 . Supports 2.3 each having an angular cross-section are fixed to both sides of the magnetic core 1.

Elastic members 6, 7 made of rubber or the like are fixed to the surfaces of the support columns 2, 3 on the medium 9 side without contacting the magnetic core 1. Furthermore, the elastic members 6 and 7 have a sliding surface 4 that contacts the medium 9.
A slider 4.5 with a, 5a is fixed.

This slider 4.degree. 5 is not in contact with the magnetic core 1 and the columns 2 and 3.

Therefore, according to the magnetic head equipped with this slider part 8, the slider part 8 However, as shown in FIG. 3, even if the slider 4 is tilted to one side, the sliding surface 4a of the slider 4 comes into contact with the medium 9 due to the pressing force of the load spring 17 (FIG. 4), and the elastic member 6 also As the magnetic core 1 is compressed, the magnetic core 1 approaches the medium 9 by the amount of compression. Therefore, a situation in which the distance between the magnetic core 1 and the medium 9 increases is suppressed.

Furthermore, when the magnetic core 1 is tilted in the opposite direction to that shown in FIG. 3, the elastic member 7 is compressed, thereby preventing the magnetic core 1 and the medium 9 from being separated greatly.

In the above embodiment, even if the slider part 11 is configured by the same means as the slider part 8, the same effect can be obtained.

[Effects of the Invention] As explained above, according to the magnetic head of the present invention, the part that supports the magnetic core is separated into three parts: the elastic member of the pillar 1 and the slider, and the elastic member and the slider are fixed to the magnetic core. Even if the slider is tilted due to machining accuracy errors, the slider contacts the medium and compresses the elastic member, and this compression brings the magnetic core closer to the medium. It is possible to prevent the distance from the core from increasing. Therefore, there is an effect that stable magnetic recording and reproduction can be performed.
