Description
본 발명은 컨택트 스타트 스톱(Contact Start Stop:이하 CSS라함)방식을 채용하는 하드 디스크 드라이브의 랜딩 존 텍스처링방법에 관한 것으로, 특히 랜딩 존상에 텍스처링되는 범프의 고도를 다원화하기 위한 텍스처링방법에 관한 것이다.The present invention relates to a landing zone texturing method of a hard disk drive employing a contact start stop (hereinafter referred to as CSS) method, and more particularly, to a texturing method for pluralizing the altitude of bumps textured on the landing zone.
컴퓨터시스템의 보조기억장치로 널리 사용되고 있는 하드 디스크 드라이브(Hard Disk Drive)는 드라이브 비사용시 헤드가 위치하는 곳에 따라 다이내믹 헤드 로딩(Dynamic Head Loading:DHL방식이라함)방식과 CSS방식으로 구분된다. 상기 CSS방식을 채용하는 하드 디스크 드라이브에 있어서는 디스크상에 랜딩존이 구비되어 있어 드라이브 비사용시 헤드 슬라이더가 상기 랜딩 존상에 위치하게 된다.Hard disk drives, which are widely used as auxiliary storage devices for computer systems, are classified into dynamic head loading (DHL) and CSS based on where the head is located when the drive is not used. In the hard disk drive employing the CSS method, a landing zone is provided on the disc so that the head slider is positioned on the landing zone when the drive is not used.
일반적으로 CSS방식을 채용하는 하드 디스크 드라이브에 있어서는 헤드/디스크 인터페이스에서의 스틱션(stiction)이나 웨어(wear)를 최소화하기 위하여 랜딩 존을 텍스처링하는 것이 일반화되어 있다. 이러한 랜딩 존 텍스처링방법으로는 메카니컬(mechanical) 텍스터링방법이 있는데 근래에는 레이저를 이용한 텍스처링방법이 널리 사용되고 있다. 그 이유는 레이저를 이용하면 랜딩 존상에 가공되는 범프의 크기, 위치나 형상등을 용이하게 조절할 수 있기 때문이다. 이하 레이저를 이용하여 랜딩 존을 텍스처링하는 종래의 방법을 구체적으로 설명하면 다음과 같다.In general, in the hard disk drive employing the CSS method, it is common to texture the landing zone in order to minimize stiction or wear in the head / disk interface. Such a landing zone texturing method includes a mechanical texturing method. Recently, a texturing method using a laser is widely used. The reason is that the laser can easily adjust the size, position or shape of the bumps processed on the landing zone. Hereinafter, a conventional method of texturing a landing zone using a laser will be described in detail.
우선 도 1은 종래 레이저 텍스처링방법을 통해 가공되는 범프(bump)의 형상을 예시한 것으로, 가공되는 범프의 형상은 원형에 의한 방법과 타원형에 의한 방법이 있다. 도 1에서 빗금친 부분은 레이저 광이 직접 조사된 부분으로 디스크 평탄면 보다 낮은 고도를 갖게 된다. 그리고 h는 형상화된 범프의 고도를 나타낸다.First, FIG. 1 illustrates a shape of a bump processed through a conventional laser texturing method, and the shape of the processed bump includes a circular method and an elliptical method. In FIG. 1, the hatched portion is a portion directly irradiated with laser light and has a lower altitude than the disk flat surface. And h represents the elevation of the shaped bumps.
도 2는 종래 레이저 텍스처링방법을 통해 형상화되는 범프가 분포하는 랜딩 존(landing zone)을 보이기 위한 디스크(2) 평면도를 도시한 것이며, 도 3은 종래 범프(4)의 고도를 보이기 위한 디스크(2) 단면도를 도시한 것이다. 우선 도 2에서 디스크(2)는 사용자 데이타가 기록되는 데이타 존(Data Zone:DZ라함)과 드라이브 비사용시 헤드 슬라이더가 위치하는 랜딩 존으로 구획된다. 상기 랜딩 존(LZ)은 헤드 슬라이더가 로딩(loading) 및 언로딩(unloading)되는 경우에 발생되는 스틱션현상을 최소화하기 위하여 도 1에 도시한 바와 같은 방법으로 범프(4)를 형상화한다.그리고 상기 랜딩 존(LZ)에 형상화되는 각 범프의 고도(h)는 도 3에 도시된 바와 같이 일정한 고도를 갖는다. 이에 따라 종래 CSS방식을 채용하는 하드 디스크 드라이브에 있어서는 헤드 파킹시 헤드 슬라이더가 평탄면인 데이타 존(DZ)에서 랜딩 존(LZ)으로 이동할때 급격한 범프 고도(h)에 의해 헤드 슬라이더가 비정상적으로 비행하게 되어 디스크(2)와 헤드 슬라이더간의 충돌을 야기시킬 수 있는 문제점이 있었다.FIG. 2 shows a plan view of a disk 2 for showing a landing zone in which bumps shaped through a conventional laser texturing method are distributed, and FIG. 3 shows a disk 2 for showing the altitude of a conventional bump 4. ) Is a cross-sectional view. First, in FIG. 2, the disc 2 is divided into a data zone (called Data Zone (DZ)) in which user data is recorded and a landing zone in which the head slider is located when the drive is not used. The landing zone LZ shapes the bump 4 in the manner shown in FIG. 1 in order to minimize the stiction that occurs when the head slider is loaded and unloaded. The altitude h of each bump shaped in the landing zone LZ has a constant altitude as shown in FIG. 3. Accordingly, in the hard disk drive employing the conventional CSS method, the head slider moves abnormally due to the sudden bump altitude h when the head slider moves from the flat zone data zone DZ to the landing zone LZ during head parking. There was a problem that can cause a collision between the disk (2) and the head slider.
따라서 본 발명의 목적은 컨택트 스타트 스톱방식을 채용하는 하드 디스크 드라이브에 있어서 헤드 슬라이더의 비행고도를 안정화시키기 위해 랜딩 존에 형상화되는 범프의 고도를 다원화할 수 있는 랜딩 존 텍스처링방법을 제공함에 있다.Accordingly, an object of the present invention is to provide a landing zone texturing method capable of pluralizing the altitude of bumps formed in a landing zone in order to stabilize the flight altitude of a head slider in a hard disk drive employing a contact start stop method.
상기 목적을 달성하기 위한 본 발명은 헤드 슬라이더를 구비하고 랜딩 존 및 데이타 존이 동일 디스크상에 존재하는 하드 디스크 드라이브의 랜딩 존 텍스처링방법에 있어서,The present invention for achieving the above object is a landing zone texturing method of a hard disk drive having a head slider and a landing zone and a data zone exist on the same disk,
상기 헤드 슬라이더의 비행고도 변이를 안정시키기 위해 상기 랜딩 존상에 텍스처링되는 범프의 고도를 다원화하여 형상화하고,In order to stabilize the flight altitude variation of the head slider, the altitude of the bump textured on the landing zone is pluralized and shaped.
상기 범프의 고도는 랜딩 존내에서 데이타 존으로 갈수록 점진적으로 낮아지는 고도로 텍스처링됨을 특징으로 한다.The bump's altitude is characterized by being highly textured, which gradually decreases toward the data zone within the landing zone.
도 1은 종래 레이저 텍스처링방법을 통해 형상화되는 범프(bump)의 예시도.1 is an illustration of a bump shaped through a conventional laser texturing method.
도 2는 종래 레이저 텍스처링방법을 통해 형상화되는 범프가 분포하는 랜딩 존(landing zone)을 보이기 위한 디스크(2) 평면도.FIG. 2 is a plan view of a disk 2 for showing a landing zone in which bumps are shaped by a conventional laser texturing method. FIG.
도 3은 종래 범프의 고도를 보이기 위한 디스크(2) 단면도.3 is a cross-sectional view of a disk 2 for showing the height of a conventional bump.
도 4는 본 발명의 일실시예에 따른 범프의 고도를 보이기 위한 디스크(2) 단면도.4 is a cross-sectional view of the disk 2 for showing the height of the bump according to an embodiment of the present invention.
이하 첨부한 도면을 참조하여 본 발명의 바람직한 일실시예에 따른 동작을 상세히 설명한다. 하기 설명 및 첨부도면에서 범프의 비행고도 및 수와 같은 많은특정 상세들이 본 발명의 보다 전반적인 이해를 제공하기 위해 나타나 있다. 이들 특정 상세들 없이 본 발명이 실시될 수 있다는 것은 이 기술분야에서 통상의 지식을 가진자에게 자명할 것이다. 그리고 본 발명의 요지를 불필요하게 흐릴 수 있는 공지 기능 및 구성에 대한 상세한 설명은 생략하기로 한다.Hereinafter, an operation according to an exemplary embodiment of the present invention will be described in detail with reference to the accompanying drawings. In the following description and the annexed drawings, numerous specific details, such as flight altitude and number of bumps, are shown to provide a more general understanding of the invention. It will be apparent to those skilled in the art that the present invention may be practiced without these specific details. And detailed descriptions of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.
도 4는 본 발명의 일실시예에 따른 범프(4)의 고도를 보이기 위한 디스크(2) 단면도를 도시한 것이다. 도 4를 참조하면, 디스크(2)는 사용자 데이타가 기록되는 데이타 존(DZ)과 드라이브 비사용시 헤드 슬라이더가 위치하는 랜딩 존(LZ)으로 구획된다. 그리고 상기 랜딩 존(LZ)은 본 발명에 따른 범프고도(h)의 점진적 천이영역(A)을 포함한다. 상기 범프고도(h)의 점진적 천이영역(A)이라함은 랜딩 존(LZ)상의 소정 영역에서부터 데이타 존(DZ)의 ID(Inner Diameter)까지 범프(4)의 고도(h)가 점진적으로 감소하도록 범프(4)를 형상화한 영역을 나타낸다. 즉 레이저 범프(4)의 고도를 데이타 존(DZ)으로 갈수록 점진적으로 낮추어 형상화하면, 헤드 슬라이더가 랜딩 존(LZ)에서 데이타 존(DZ)으로 로딩 및 언로딩될때 범프 고도(h)의 점진적인 변화를 보다 부드럽게 따라 갈 수 있게 됨으로서 종래와 같이 급격한 표면조도의 변화로 야기될 수 있는 디스크(2)와 헤드 슬라이더간의 충돌을 사전에 방지할 수 있게 된다.4 shows a cross-sectional view of the disc 2 for showing the altitude of the bump 4 according to one embodiment of the invention. Referring to Fig. 4, the disc 2 is divided into a data zone DZ in which user data is recorded and a landing zone LZ in which the head slider is located when the drive is not used. In addition, the landing zone LZ includes a gradual transition area A of the bump altitude h according to the present invention. The gradual transition area A of the bump height h means that the elevation h of the bump 4 gradually decreases from a predetermined area on the landing zone LZ to an ID (Inner Diameter) of the data zone DZ. The area | region which shaped the bump 4 so that it may be shown is shown. In other words, if the altitude of the laser bump 4 is gradually lowered to the data zone DZ to be shaped, a gradual change in the bump altitude h when the head slider is loaded and unloaded from the landing zone LZ to the data zone DZ. By being able to follow more smoothly, it is possible to prevent the collision between the disk 2 and the head slider, which may be caused by a sudden change in surface roughness as in the prior art.
상술한 바와 같이 본 발명은 랜딩 존의 최내주 영역에서 최외주 영역으로 이동하면서 범프의 고도를 점진적으로 낮게 형상화함으로서 헤드슬라이더의 비행거동을 안정화시킬 수 있는 잇점이 있다.As described above, the present invention has the advantage of stabilizing the flight behavior of the head slider by gradually shaping the altitude of the bump while moving from the innermost region to the outermost region of the landing zone.
