DETAILED DESCRIPTION OF THE INVENTION (a) Technical Field of the Invention The present invention relates to a magnetic head used for flexible disk storage, in particular, an erasing core is placed on both sides of a reading core, and system sliders are installed on both sides. The adhesive strength of the head made of glass or resin adhesive is h

(b) Discrepancies between the prior art and conventional technology The conventional head used for flexible paint coating is of the type shown in FIG. 1, for example. In the figure, the Qi hand A is 1. 2. Based on the structure of five parts of 3.4°5, parts 1 and 5 are sliders, parts 2 and 4 are erase cores, and parts 3 are read/write cores. &ru is done by crow contact or paulownia fat adhesion,
5 pine parts 1, 2 from the direction of 6 and 7. 3. 4.
Remove the sutures while pressing 5. In addition, parts 1 and 5 are made of ceramic paulownia to make the drawing part ♀lit, part 2 is made of transparent Mn-Zn ferrite 8, 9 and ceramic @10, and part 3 is made of ceramic. @11 and I
VLn-Zn ferrite l 2, 13 to part 4
consists of 'b1n-Zn ferrite 14.15 and ceramic IJ' 16.

If the magnetic head wanders around and is attacked by a bird, it is likely to generate dust, which can cause hend crush and damage the disk body. 0. In the case of glass bonding, parts 1 to 5 are layered using a jig, and 6
, Glass bonding is performed in a high-temperature furnace using pressure applied from seven directions. Place a glass rod at 17.18 on sliders 1 and 5, and the glass melts with the heat of the high-temperature furnace (around 45111 IC) and flows into parts 2, 4 and 3.
Furthermore, it flows between the contact surfaces, and by cooling it, it is possible to bond the glass. At this time, there was a drawback that the broken crows flowed out to the outside of the slider part 1.5, or even flowed in the direction of the arrow. For this reason, there was a problem in that not enough of the glass remained after cooling, resulting in poor contact strength. Naori is head cedar Al71; I17
direction.

Fig. 2 shows the magnetic head after adhesion, and in the subsequent process, the gap depth will be increased and the head sliding surface will be chamfered (indicated by point melting). Because the material was weak, it sometimes peeled off.

The purpose of the present invention is to provide a flexible deflector and a kettle head with a shape that prevents the glass from flowing when it comes in contact with the glass or prevents the adhesive from flowing when bonding the handle and increases the adhesive strength. It's a matter of fact.

(d) Construction of the invention According to the present invention, in a nitrogen gas head constructed by expanding a ridge-enhancing portion core and an erasing portion core with a syswriter and bonding them with glass, A bent part to prevent the glass from flowing during most of the time is attached to the media inlet end I1, and a glass rod for glass 41X is attached to the glass adhesive side of the VCITF slider.

This can be achieved by providing a head that is characterized by having a tapered portion for the purpose.

(e) Actual sister example of the invention Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 3 is a perspective view illustrating one example of the b-air head of the present invention.

In the figure, the head A' is l', 2', 3',
Consists of #layer structure of 5 parts of 4'+5', part 1
', 5' are sliders, parts 2', 4' are erase cores, and part 3' is a read/write core (iF, fi/included core).

Slider parts 1/, 5/Genjoku's slider parts 1゜5
Tapers 19 and 20 for storing glass rods for glass stirring or for flowing adhesive are provided so that it flows easily to the scratching Xi surface side. Parts 2/4 of the dissipating core 2/4/On one side (#; the side where the body is worn) of the parts 2 and 4 of the dissipating core, there is a glass flow prevention piece or a bent part 21 for preventing adhesive flow. .22 is provided. The read/write core part 3' is the same as the conventional read/write core part 3.

As shown above, taper 1 on slider part 1/, 5/
9°, 20 are provided, and the bent portion 2 is provided on the erasing core parts 21, 4'.
1゜22 is provided, and each part 1' to 5' is assembled using a jig;
Then, while applying pressure from the 23 and 24 directions, the above Taber 1
In the case of glass bonding in 9.20, remove the glass rod and perform glass bonding in a high temperature furnace. At this time, the gas rough/rod is stably held by the tabers 19 and 20, and the transporter into the furnace is not displaced, so that the slow transport work can be easily carried out. Also, sweat 1. I*+' The crow flows only to the erasure core part, read/write part i] of sliders 1' and 5' by Taber 9.20, and the outer bones of sliders 1' and 5'. There is no flow to 1.

The crows flowing into the inner ribs 1 of these sliders', 5' are stopped by the bent parts 21.22 of the erased core parts 2', 4', and the crows corresponding to the height of this bending s21.22 are 15
Since it remains after cooling without klfj, the strength of the glass bond increases accordingly. Therefore, the V layered in the state of etiquette
As a result of being able to bond strongly enough between fX products 1' to 5' with Gakarasu gouge, it is possible to use the gap depth dimension in the subsequent process, and to increase the R1Ir1 force of the head joint skin/simplification [in 1 machining, compared to the conventional one]. There is no scraping with the slider and core 1hi. In the case of resin adhesion using a wafer additive, the adhesive is poured along the taper, and after the ζ gradual attack agent has been accumulated sufficiently until the bending height is +τp, the adhesive is heated at 120°C. Let's warm it up with heat.

Since the repellent is sufficiently spread up to the height of the bending part, R in the subsequent process is
(1!4j of (f:(j) in the AP(Ruffin process) becomes.

FIG. 4 shows another implementation side 1 of the present invention. This is a cross-sectional view of the present invention applied to a crane head having a recess 25 on the slider.

Since one slider 1# has a recess 25, the recess 2
Tapers 26 and 27 are provided on both sliders 5 (1ji), and the taper 28 of the other slider 5'' is the same as that of the slider 5' shown in FIG.

By configuring as above, carving 3 and 4 result in yh.

The bent portions 21 and 22, which have exactly the same effect as described above, serve to prevent the adhesive from flowing out when injecting the adhesive in the tree Jli'+ bonding, and also serve to prevent the adhesive from flowing out when the adhesive is injected.
When injecting the 20d adhesive, the adhesive will soak in along the 100 degrees, so urine will play the role of preventing the adhesive from flowing out.

(fl) Effects of the Invention As described in detail above, the magnetic head of the present invention has a bent portion on one side of the five cores of the eraser for preventing the glass curvature rt1 or Vi adhesive from flowing, and also has a glass plate on the slider. By creating a taper for the glass plume for the contact layer, or as a mirror for the grafting agent M1, the glass or the grafting agent for the height of the bending part will remain after cooling without flowing out. The taper increases the bonding strength and prevents the molten glass or f&lh agent from leaking out to the outside of the erase core b1).
, since it flows only to the read/write part side, as a result of compensating and cleaning up the 4th part, it is stronger than the traditional one and the 9th strong exhibition was achieved.
It can increase the strength during machining, and can also be used. I was able to increase it.
