1c : 선단부 2 : 소거코어1c: tip 2: eraser core

3 : 비자성물질 4, 6 : 전면판3: nonmagnetic material 4, 6: front panel

본 고안은, 자기디스크장치용 자기헤드에 관한 것이며, 특히 기록 재생 코어의 형상의 개량에 관한 것이다.The present invention relates to a magnetic head for a magnetic disk device, and more particularly, to an improvement in the shape of a recording / reproducing core.

제1(a)도, 제1(b)도에 종래예의 자기헤드의 구성을 나타내면 다음과 같다.The structure of the magnetic head of the prior art is shown in FIG. 1 (a) and FIG. 1 (b) as follows.

동도면(a)은 분해외관사시도이며, 1은 기록 재생 갭(1a)을 형성한 페라이트등의 자성재료로써 이루어진 기록 재생코어이고, 다리부(1b)를 설치하고 있다.FIG. 1A is an exploded perspective perspective view, wherein 1 is a recording / reproducing core made of a magnetic material such as ferrite having a recording / reproducing gap 1a, and the leg portion 1b is provided.

2는 기록 재생코어(1)의 양측에 병설된 페라이트등의 자성재료로써 이루어진 소거코어로서 각각 유리등의 비자성물질(3)을 설치하고 있다. 4는 소거코어(2)를 삽입하는 홈부(溝部)(4a)를 설치한 세라믹등의 비자성물질로써 이루어진 전면판이며, 한쌍의 소거코어(2), (2) 및 한쌍의 전면판(4), (4)이 기록 재생코어(1)를 끼고 대향하고 있다.2 is an erasing core made of magnetic material such as ferrite provided on both sides of the recording / reproducing core 1, and nonmagnetic materials 3 such as glass are provided respectively. 4 is a front plate made of a nonmagnetic material such as ceramic provided with a groove portion 4a for inserting the erasing core 2, and a pair of erasing cores 2, 2 and a pair of front plates 4 are provided. ) And (4) oppose each other with the recording and reproducing core 1.

동도면(b)은 이들 각부재를 조립한 상태의 외관사시도이다.The same figure (b) is an external perspective view of the state which assembled each member.

이와 같이 조립할때에는 소거코어(2), (2)사이에 소정치수의 소거갭(2a)이 형성되도록 소거코어(2), (2)를 위치결정하여 임시고정한 후 유리등의 결합재료에 의해 고정한다.When assembling in this way, the erase cores 2 and 2 are positioned and temporarily fixed so that an erase gap 2a of a predetermined size is formed between the erase cores 2 and 2, and then fixed by a bonding material such as glass. do.

이와같은 종래의 자기헤드에 있어서는 기록 재생코어(1)는 자기 디스크와 대향하는 일단부에서 다리부(1b)에 이르기까지 그 판두께가 균일하게 되도록 구성되어 있다.In such a conventional magnetic head, the recording / reproducing core 1 is configured such that the plate thickness is uniform from one end portion facing the magnetic disk to the leg portion 1b.

그런데 최근 전자계산기의 보급에 따라 그 외부기억장치로서의 자기디스크장치가 증가되어 오고 있음과 동시에, 그 고속화, 대용량화에 수반하여 보다 기억밀도의 향상이 요구되고 있으며, 편면에서 양면타입, 단밀도에서 배밀도, 더 나아가서 기록트랙의 협(狹)트랙화로 고밀화가 진행되고 있다.Recently, with the spread of electronic calculators, magnetic disk devices as external memory devices have increased, and as the speed and capacity have increased, memory density needs to be improved. Increasingly densified by density and further narrowing of recording tracks.

종래의 자기헤드에 있어서는 고밀도, 협트랙에 대응하기 위하여 기록 재생코어(1)의 판두께를 극히 얇게 해왔었다. 그런데 상술한 바와 같이, 이 기록 재생코어(1)는 전체적으로 균일한 판두께로 되어 있었기 때문에 판두께를 얇게하면 할수록 그 기계적 강도는 저하되기 마련이다. 그 결과 전면판(4)에서 노출된 다리부(1b)가 접힌다고 하는 좋지못한 상태가 발생되고 있었다.In the conventional magnetic head, the plate thickness of the recording / reproducing core 1 has been extremely thin in order to cope with high density and narrow track. As described above, since the recording and reproducing core 1 has a uniform plate thickness as a whole, the thinner the plate thickness, the lower the mechanical strength. As a result, the bad state that the leg part 1b exposed by the front plate 4 was folded was produced.

본 고안은 이상과 같은 종래예의 결점을 감안하여 이루어진 것으로, 고밀도, 협트랙화된 자기디스크에 충분히 대응할 수 있고, 더구나 다리부의 강도도 큰 자기헤드를 제공하는 것을 목적으로 하는 것이다.This invention is made in view of the fault of the prior art as mentioned above, and an object of this invention is to provide the magnetic head which can fully respond to a high-density, narrow-tracked magnetic disk, and also has the big leg strength.

그리고 이를위해 기록 재생코어의 디스크 슬라이딩면으로 되는 선단부의 폭을 다리부의 폭보다 가늘게하고, 협트랙에 충분히 대응할 수 있도록 함과 함께, 다리부의 기계적 강도를 선단부에 비하여 증강하도록 장치를 구성한 것이다.To this end, the device is configured to make the width of the tip portion, which becomes the disk sliding surface of the recording / reproducing core, narrower than the width of the leg portion, to sufficiently cope with the narrow track, and to increase the mechanical strength of the leg portion relative to the tip portion.

이어서 본 고안의 구성을 제2도, 제3도에 나타낸 실시예에 의거하여 설명하면 다음과 같다. 그리고 제1도에 나타낸 종래예와 동일한 곳에는 동일부호를 붙이기로 하겠다.Next, the structure of the present invention will be described based on the embodiment shown in FIG. 2 and FIG. The same reference numerals will be given to the same parts as in the conventional example shown in FIG.

제2(a)도, 제2(b)도는 본 고안이 일 실시예에 관계되는 자기헤드를 나타낸 것으로서, 동도면(a)은 그 분해외관 사시도이고, 동도면(b)은 각 부재를 조립한 상태의 외관 사시도이다.Figure 2 (a), Figure 2 (b) is a magnetic head according to an embodiment of the present invention, the same figure (a) is an exploded appearance perspective view, the same figure (b) assembling each member It is an external perspective view of one state.

도면에 나타낸 바와 같이 본 고안에 있어서의 기록 재생코어(1)는 디스크 슬라이딩면으로 되는 선단부(1C)의 폭을 가늘게(좁게)하여 협트랙에 대응시키는 한편, 다리부(1b)의 폭을 넓게한 것이다.As shown in the figure, the recording / reproducing core 1 of the present invention narrows (narrows) the width of the tip portion 1C serving as the disk sliding surface to cope with the narrow track, while widening the width of the leg portion 1b. It is.

그리고 종래예와 마찬가지로 이 선단부(1C)를 한쌍의 전면판(4), (4)의 사이에 수납한다. 전면판(4)의 아래쪽에는 다리부(1b)가 노출하고 있지만 기계적 강도는 종래의 것과 비교하면 증강되고 있다.And the tip part 1C is accommodated between a pair of front plate 4 and 4 similarly to a conventional example. Although the leg part 1b is exposed under the front plate 4, mechanical strength is being strengthened compared with the conventional one.

제3도는 다른 실시예에 관계되는 자기헤드의 분해외관 사시도이다.3 is an exploded perspective view of the magnetic head according to another embodiment.

이 실시예에서도 기록 재생코어(1)의 선단부(1C)의 폭은 다리부(1b)에 비교하면 가늘게 되어 있다.Also in this embodiment, the width of the tip portion 1C of the recording / reproducing core 1 is thinner than the leg portion 1b.

5는 2개의 소거코어(2), (2)를 비자성물질(3)로서 연결한 소거코어칩이며, 이 비자성물질(3)의 일단에는 소정치수의 홈부(3a)가 형성되어 있다.5 is an erasing core chip in which two erase cores 2 and 2 are connected as a nonmagnetic material 3, and one end of the nonmagnetic material 3 is provided with a groove portion 3a of a predetermined dimension.

6은 세라믹등으로된 전면판이며, 제1홈(6a), 제2홈(6b) 및 경사홈(6c)이 형성되어 있다.6 is a front plate made of ceramic or the like, and the first groove 6a, the second groove 6b and the inclined groove 6c are formed.

7은 이들의 구성부재를 결합하는 비자성결합재료이다. 이들의 구성부재의 조립은 먼저 전면판(6)의 제1홈(6a)에 기록재생코어(1)를, 제2홈(6b)에 소거코어칩(5)을 각각 삽입한다. 이때 소거코어칩(5)의 비자성물질(3)의 홈부(3a)에 기록 재생코어(1)의 선단부(1C)가 삽입된다. 다음에 전면판(6)의 경사홈(6c)에 유리등의 비자성결합재료(7)를 놓고 각 구성부재를 결합한다.7 is a nonmagnetic coupling material which couples these structural members. In the assembly of these constituent members, the recording / reproducing core 1 is first inserted into the first groove 6a of the front plate 6 and the erasing core chip 5 is inserted into the second groove 6b, respectively. At this time, the tip portion 1C of the recording / reproducing core 1 is inserted into the groove portion 3a of the nonmagnetic material 3 of the erase core chip 5. Next, a nonmagnetic bonding material 7 such as glass is placed in the inclined groove 6c of the front plate 6, and the respective constituent members are joined.

이 구성에 있어서, 협트랙에 대응하는 자기헤드를 제조하기 위해서는, 소거코어칩(5)의 비자성물질(3)의 홈부(3a)에 삽입되는 기록 재생코어(1)의 선단부(1C)만을 가늘게하면 충분하다.In this configuration, in order to manufacture the magnetic head corresponding to the narrow track, only the tip 1C of the recording / reproducing core 1 inserted into the groove portion 3a of the nonmagnetic material 3 of the erasing core chip 5 is manufactured. Thinner is enough.

따라서 다리부(1b)의 기계적 강도는 저하되지 않는다.Therefore, the mechanical strength of the leg 1b does not fall.

본 고안은 이상 설명한 바와 같이 기록 재생 코어중 디스크 슬라이딩 면으로 되는 선단부의 폭만을 가늘게 한 것이므로 고밀도, 협트랙을 갖는 디스크에 대응할 수 있을 뿐만 아니라, 접히거나 부러짐이 발생하기 쉬운 기록 재생코어의 다리부의 기계적 강도를 저하시키는 일이 없다. 또 이로 말미암아 자기회로를 굵게 취할 수 있으며, 자기 저항이 적고 로스도 적은 고능률의 자기 헤드가 얻어진다고 하는 효과도 있다.As described above, since only the tip portion of the recording and reproducing core becomes the sliding surface of the recording and reproducing core, it can not only correspond to a disc having a high density and narrow track, but also the leg portion of the recording and reproducing core, which is easily folded or broken. The mechanical strength is not lowered. This also makes it possible to make the magnetic circuit thicker, and has the effect that a highly efficient magnetic head with less magnetic resistance and less loss is obtained.
