Abstract

PURPOSE:To reduce form effect noise by arranging a pair of core pieces of a core part along a direction that intersects the direction of running of a recording medium. CONSTITUTION:A core part 12 made of magnetic material such as, for instance, Mn-Zn ferrite, is fixed to the slanted face 19 around a slider part 11 made of non-magnetic material through a bonding agent such as glass. A pair of core pieces 15, 16 facing each other through a gap 14 provided in the direction nearly at right angles to the direction of running of a recording medium shown by the arrow mark are arranged to face on the slanted face 19 that intersects the above-mentioned direction at theta deg.. Accordingly, when the recording medium runs on the gap 14, it does not pass on the end faces 17, 18 together. A coil 21 is wound on one core piece 16 of the core part 12 through a groove 20, and a groove 22 is provided in the slider part 11 to make winding easily.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a floating magnetic head fixed to a core slider section.

[Conventional technology]

The third worst structure is known as a floating magnetic head in which the core part is fixed to a movable slider part. In the same figure (a
t is the surface area, tb is the surface area, and the core part 2 is made of a magnetic material in the pressure device of the slider part 1 made of a non-flexible material.
The Jal a is fixed by being bath-bonded with glass 3. The core part 2 has a gap 4 provided in a circle perpendicular to the recording medium running direction indicated by the arrow, and a part 1 facing parallel to the direction of the above-mentioned arrow through this gap 4.
core piece 5°6, and a coil (not shown) attached to the core piece 5 or 6? : Sealed. Further, the core hβ2 is provided with an end side 7.8 parallel to the gap 4.

[Problems that Komei tries to solve]

However, the conventional Yuzo's PP Tai type magnetic head has the following problems.

(1) When the recording medium runs on the gear foot 4, it also passes over the edges 7 and 8, so that so-called shape effect noise occurs.

(2) When the glass 3 layer is used, the stress caused by the difference in material resistance between the glass 3 and the slider part 1 is applied to the core s2, which deteriorates the performance.

(If a part of the 37 core part 2 is made of an ordinary orange material, a secondary gap will occur at this boundary.

(4) Since the area around the gap 4 is buried in the slider ml via the crow 3, it is impossible to measure gear spacing.

The object of the present invention is to provide a new conventional floating magnetic head that solves these problems.

[Means for solving total points]

In order to achieve the above object, the present invention provides a floating magnetic head odor in which a core ilB made of a magnetic material is fixed to a slider part made of a non-magnetic material, and a gap provided in a direction substantially perpendicular to the running direction of the recording medium. A pair of core pieces facing each other are fixed to the slider portion so as to be parallel to each other in a direction perpendicular to the traveling direction of the recording medium. This is a characteristic feature.

[Effect]

The core area is distributed in a direction that intersects with the traveling direction of the ball distribution medium, facing each other through a gap, and for example, only the one-time surface is fixed to -hμ around the slider part via adhesive. be done. Therefore, unlike the conventional structure, the pair of core pieces of the busy core portion are not arranged parallel to the recording medium running direction.

[Real lttM example]

Below, the present invention will be explained in detail with reference to its four aspects.

The disk is fixed via a core 12 made of a magnetic material such as Mn--Zn ferrite or an adhesive 13 such as glass. The gear lug 14 is arranged almost perpendicularly to the recording medium traveling direction as shown by the arrow? : A pair of core pieces 15 and 16 facing each other are arranged so as to rotate around each other on the tilting plate @19 that intersects with the above direction at a distance of 01. : Edge 17 when the recording medium runs

The slider portion 11 is also provided with grooves to facilitate winding. B is Nonte. TW indicates the dosink width of the recording medium corresponding to the width of the camp 14.

(Second implementation) Figure 2(a), tbJ shows the second implementation example of the present invention.
Compared to the first embodiment, this embodiment shows a structure in which the core s12 is arranged on a surface 19 opposite to the f+ surface 19 with respect to the recording medium traveling direction. The composition of this pond is the same as the first one.

〔Effect of the invention〕

As explained above, according to the present invention, the pair of core pieces of the core are arranged along the direction intersecting the running direction of the recording medium, and as a result, the following effects can be obtained.

(1) IC passing over gap 14: Recording medium is on edge 1
Since at least one ρ rie on 7°18 passes only on 18, shape effect noise is reduced.

(2) Since only one side of the core cap 12 is fixed to the slider portion via adhesive, there is almost no stress.

(3) The gold maple material is conveniently used as a decoration of the core toki, and no secondary gap occurs.

(4) Since the gap 150 laps is not buried in the slider section, the gap depth can be easily measured through the glass.
