Description

자기헤드 지지장치(Apparatus For Supporting A Magnetic Head)Apparatus For Supporting A Magnetic Head

본 발명은 기록매체의 기록/재생장치에 관한 것으로, 특히 자기헤드가 형성된 자기헤드를 지지하는 자기헤드 지지장치에 관한 것이다.The present invention relates to a recording / reproducing apparatus of a recording medium, and more particularly to a magnetic head support apparatus for supporting a magnetic head having a magnetic head formed thereon.

최근, 자계변조 기록방식을 채택하는 광자기 디스크(Magneto Optical Disk ; 이하 "MOD"라 함)가 차세대 주보조기억 장치로 각광을 받으면서 대용량으로 발전하고 있다. 현재까지 상용화되고 있는 MOD는 120mm 외경의 디스크에 약 650 MB의 정보를 기록/재생할 수 있으며, 향후 6 GB 또는 14 GB 까지 대용량화될 전망에 있다. 현재의 MOD 기록방식에서 자기헤드가 취부된 자기헤드 슬라이더는 필연적으로 디스크 표면에 접촉하는 과정을 겪어야만 한다. 이 자기헤드 슬라이더는 크게 습동형(Sliding Contact type)과 부상형(Flying type)으로 나뉘어 진다. 자기헤드 슬라이더가 습동형인 경우 정보기록의 개시시점에서 자기헤드 슬라이더는 디스크 표면과 접촉되고(Contact Start) 정보기록 완료시점에서 디스크 표면과의 접촉이 종료(Contact Stop)된다. 자기헤드가 부상형인 경우에는 정보기록시 자기헤드 슬라이더 자체의 관성에 의해 자기헤드가 디스크 표면과 접촉을 순간적으로 하게되는 과도기적 시간(Transient time)을 겪게 된다. 이 부상형 자기헤드 슬라이더는 자체의 운동에너지에 의해 디스크 표면에 안착하는 순간에 접촉이 시작되며(Contact start), 디스크가 회전함에 따라 디스크 표면에 유속이 발생하게 되면 자기헤드와 디스크 표면사이의 유속에 의한 압력이 발생되면서 자기헤드 슬라이더는 자체 하중 및 인가 하중을 이겨내는 순간에 디스크 표면과의 접촉이 종료되며 디스크 표면으로부터 부상하게 된다. 이와 같이, 광자기 기록/재생 장치의 자기헤드 슬라이더는 습동형 또는 부상형의 어느 방식을 채택하더라도 기록과정 중 디스크 표면과의 접촉개시/종료(Contact Start Stop ; 이하 "CSS"라 함)과정을 필연적으로 겪게 된다. 이 CSS 과정에 의해 자기헤드의 억세스 타임은 디스크 표면에 접촉 또는 부상하는 경과시간만큼 지연된다. CSS 과정에서 주위환경이 습하게되는 경우, 점성(viscosity)이 높아지기 때문에 디스크 정지시 자기헤드 슬라이더와 디스크가 흡착되어 붙는 현상이 흔히 발생하게 된다. 이 상태에서, 디스크가 기동되어 회전되면 긁힘현상(Scratch)이 발생하게 되어 디스크의 정보 기록면과 자기헤드 슬라이더의 습동면을 손상시키게 되고 심한 경우, 자기헤드를 손상시키게 된다. 또한, CSS 과정에서 디스크 표면과 자기헤드 슬라이더간의 접촉에 의해 디스크 표면에 충격이 가해지게 되는데, 이 역시 디스크의 손상을 야기시키게 된다. 이러한 CSS 과정에 따른 접촉에 의한 디스크의 손상을 방지하도록 자기헤드 슬라이더를 지지하게되는 지지구조는 탄성스프링구조를 갖게 된다. 그러나 이러한 지지구조는 저강성의 탄성스프링구조를 취하게 되기 때문에 탄성력에 의해 로딩/언로딩(Loading/Unloading) 동작시자체의 진동을 유발하기 쉬운 구조가 불가피하게 된다. 더욱이, 이러한 지지구조는 디스크에 대한 반경방향과 원주방향에 대해서 강성을 갖지 못하기 때문에 디스크 회전시 공기유동에 의해 큰 진폭으로 진동되어 일정 높이를 유지하여야 하는 부상높이를 안정하게 유지시키는 것이 실질적으로 불가능하였다. 이는 근본적으로 CSS 과정을 겪는 데에서 나타나는 문제점들로서 고밀도·고배속화 추세에 있어서, 신속한 억세스 타임과 기록의 정확성을 확보하기 위하여 CSS 과정이 생략된 새로운 방안이 요구되고 있다.Recently, a magneto-optical disk ("MOD") adopting a magnetic field modulation recording method has developed into a large capacity as it is spotlighted as a next-generation main auxiliary memory device. MOD, which is commercially available up to now, can record / play back about 650 MB of information on a 120mm outer diameter disk, and is expected to increase its capacity to 6 GB or 14 GB in the future. In the current MOD recording method, the magnetic head slider mounted with the magnetic head inevitably undergoes contact with the disk surface. This magnetic head slider is largely divided into sliding contact type and floating type. When the magnetic head slider is sliding, the magnetic head slider is in contact with the disk surface at the start of information recording, and the contact with the disk surface is terminated at the completion of the information recording. When the magnetic head is floating, the inertia of the information magnetic magnetic head slider itself causes a transient time in which the magnetic head makes instant contact with the disk surface. This floating magnetic head slider is contacted at the moment when it is seated on the disk surface by its kinetic energy (Contact start), and when the flow rate is generated on the disk surface as the disk rotates, the flow rate between the magnetic head and the disk surface As a result of the pressure generated by the magnetic head slider, the contact with the disk surface is terminated and rises from the disk surface at the moment of surmounting the self load and the applied load. As such, the magnetic head slider of the magneto-optical recording / reproducing apparatus has a Contact Start Stop (hereinafter referred to as " CSS ") process on the surface of the disc during the recording process regardless of the sliding type or floating type. It is inevitable. By this CSS process, the access time of the magnetic head is delayed by the elapsed time of contacting or floating on the disk surface. When the surrounding environment becomes wet during the CSS process, since the viscosity increases, the magnetic head slider and the disk are attracted to each other when the disk is stopped. In this state, when the disk is started and rotated, scratches occur, which damages the information recording surface of the disk and the sliding surface of the magnetic head slider and, in severe cases, the magnetic head. In addition, in the CSS process, the disk surface is impacted by the contact between the disk surface and the magnetic head slider, which also causes damage to the disk. The support structure for supporting the magnetic head slider to prevent damage to the disk due to the contact caused by the CSS process has an elastic spring structure. However, since this support structure takes a low rigid elastic spring structure, it is inevitable that the structure is susceptible to vibration of the self during loading / unloading operation by the elastic force. Moreover, since this support structure does not have rigidity in the radial and circumferential directions with respect to the disk, it is practically stable to maintain the height of the float, which is oscillated with a large amplitude by air flow during the rotation of the disk, thereby maintaining a constant height It was impossible. This is fundamentally a problem that occurs in the CSS process, and in the trend of high density and high speed, a new method in which the CSS process is omitted is required to secure fast access time and record accuracy.

따라서, 본 발명의 목적은 기록매체와 자기헤드 슬라이더 간의 흡착에 의한 손상을 방지하도록 한 자기헤드 지지장치를 제공하는데 있다.Accordingly, it is an object of the present invention to provide a magnetic head support apparatus which prevents damage caused by adsorption between a recording medium and a magnetic head slider.

본 발명의 다른 목적은 CSS 과정을 생략할 수 있도록 한 자기헤드 지지장치를 제공하는데 있다.Another object of the present invention is to provide a magnetic head support device to omit the CSS process.

본 발명의 또 다른 목적은 우수한 부상특성을 갖도록 한 자기헤드 지지장치를 제공하는데 있다.It is still another object of the present invention to provide a magnetic head support device having excellent floating characteristics.

A floating height control member for reinforcing the rigidity of the member is provided.

상기 목적들 외에 본 발명의 다른 목적 및 잇점들은 첨부한 도면을 참조한 실시예에 대한 설명을 통하여 명백하게 드러나게 될 것이다.Other objects and advantages of the present invention in addition to the above objects will become apparent from the description of the embodiments with reference to the accompanying drawings.

이하, 본 발명의 실시예들을 첨부한 도 1 내지 도 6를 참조하여 상세히 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to FIGS. 1 to 6.

도 1은 본 발명의 실시예에 따른 자기헤드 지지장치의 분해 사시도를 나타낸다. 그리고 도 2는 도 1에 도시된 자기헤드 지지장치가 조립된 상태를 나타내기 위한 사시도이며, 도 3은 도 2에 도시된 자기헤드 지지장치를 위에서 본 평면도를 도시한 것이다.1 is an exploded perspective view of a magnetic head support device according to an embodiment of the present invention. 2 is a perspective view illustrating an assembled state of the magnetic head support device illustrated in FIG. 1, and FIG. 3 is a plan view of the magnetic head support device illustrated in FIG.

도 1의 구성에서, 본 발명의 자기헤드 지지장치는 적어도 하나 이상의 도시하지 않은 자기헤드가 저면에 취부되는 자기헤드 슬라이더(2)와, 자기헤드 슬라이더(2)를 탄성지지하는 서스펜션암(4)과, 서스펜션암(4)에 체결되는 부상높이 규제 스프링(이하 "F/H 스프링"이라 함)(6)을 구비한다.In the configuration of FIG. 1, the magnetic head support apparatus of the present invention includes a magnetic head slider 2 having at least one unillustrated magnetic head mounted on a bottom thereof, and a suspension arm 4 elastically supporting the magnetic head slider 2. And a lift height regulating spring (hereinafter referred to as "F / H spring") 6 fastened to the suspension arm 4.

도 1 내지 도 3을 참조하면, 서스펜션암(4)과 F/H 스프링(6)은 취부홀(8a)을 관통하여 나사(10)로 고정부에 체결된다. 서스펜션암(4)에는 막대형의 가이드홀(4a)이 형성되고 일단에는 자기헤드 슬라이더(2)가 취부된다.1 to 3, the suspension arm 4 and the F / H spring 6 are fastened to the fixing part with the screw 10 through the mounting hole 8a. The suspension arm 4 is formed with a rod-shaped guide hole 4a, and one end of the magnetic head slider 2 is mounted.

F/H 스프링(6)은 디스크(1)에 대한 자기헤드 슬라이더(2)의 부상높이를 일정이상으로 규제함과 아울러, 서스펜션암(4)의 강성을 보강하는 역할을 하게된다. 또한, F/H 스프링(6)은 서스펜션암(4)에 가해지는 진동을 흡수함으로써 서스펜션암(4)에 가해지는 진동에 따른 진폭량을 감쇄시키는 역할을 하게 된다. 이를 위하여, F/H 스프링(6)은 십자형(+) 판스프링으로 이루어진다. 이 F/H 스프링(6)은 고정판(6c)으로부터 서스펜션암(4)의 길이방향으로 신장되는 지지부(6b)와, 지지부(6b)의 중간지점에서 서스펜션암(4)의 폭방향으로 신장되는 두 개의 날개부(6a)를 구비한다. 지지부(6b)는 도면에서 일점쇄선으로 나타낸 화살표와 같이, 서스펜션암(4)의 아래쪽에서 가이드홀(4a)을 관통하여 서스펜션암(4) 윗쪽으로 돌출된다. 또한 도 4와 같이, 지지부(6b)는 소정 각도로 절곡되어 서스펜션암(4)을 위에서 아래쪽으로 작용하는 일정 인가하중을 부가함으로써 서스펜션암(4)이 기록동작 중 공기유동의 편차에 의한 큰 부상력으로 서스펜션암(4)이 디스크(1) 표면으로부터 부상높이 이상으로 이탈하는 것을 방지하는 역할을 하게 된다. 날개부(6a)는 지지부(6b)와의 접변에서 단턱부를 형성함으로써 가이드홀(4a)의 폭에 해당하는 길이만큼 자기헤드 슬라이더(2)의 부상높이를 규제하여 자기헤드 슬라이더(2)의 부상높이를 일정하게 유지시키는 역할을 하게 된다. 또한, 날개부(6a)는 서스펜션암(4)의 폭방향으로 서스펜션암(4)을 아래에서 지지하는 역할을 하게 된다.The F / H spring 6 regulates the height of lift of the magnetic head slider 2 relative to the disk 1 to a certain level and serves to reinforce the rigidity of the suspension arm 4. In addition, the F / H spring 6 serves to attenuate the amount of amplitude due to the vibration applied to the suspension arm 4 by absorbing the vibration applied to the suspension arm 4. For this purpose, the F / H spring 6 consists of a cross-shaped leaf spring. The F / H spring 6 extends in the width direction of the suspension arm 4 at a midpoint of the support portion 6b extending from the fixed plate 6c in the longitudinal direction of the suspension arm 4 and the support portion 6b. Two wings 6a are provided. The supporting portion 6b protrudes above the suspension arm 4 through the guide hole 4a at the lower side of the suspension arm 4 as indicated by the dashed-dotted line in the figure. In addition, as shown in Fig. 4, the support portion 6b is bent at a predetermined angle to add a constant applied load which acts on the suspension arm 4 from top to bottom, causing the suspension arm 4 to be greatly injured due to variations in air flow during the recording operation. Force serves to prevent the suspension arm 4 from escaping above the flotation height from the surface of the disk 1. The wing portion 6a forms a stepped portion at the contact with the support portion 6b to regulate the lift height of the magnetic head slider 2 by the length corresponding to the width of the guide hole 4a, thereby raising the lift height of the magnetic head slider 2. It is to keep the constant. In addition, the wing portion 6a serves to support the suspension arm 4 from below in the width direction of the suspension arm 4.

이를 도 5 및 도 6을 참조하여 상세히 하면, 서스펜션암(4)의 가이드홀(4a)은 a의 폭으로 설정된다. 이 가이드홀(4a)의 제1 절결선(L1)은 자기헤드 슬라이더(2)가 디스크 표면(1)에 접촉되는 것을 방지하는 부상높이의 하한높이에 해당한다. 기록동작이 완료되어 디스크(1)가 정지하게 되면 자기헤드 슬라이더(2)는 서스펜션암(4)의 인가하중에 의하여 디스크(1) 표면으로 접촉되려 할 것이다. 이 때, 서스펜션암(4)은 고정부(8)를 중심으로 일정 각도로 선회하여 디스크(1) 쪽으로 내려오고 F/H 스프링(6)은 상대적으로 도 6a의 상태에서 도 6b의 상태로 자기헤드 슬라이더(2) 쪽으로 신장된다. 서스펜션암(4)이 디스크쪽으로 내려오는 어느 시점에서 지지부(6b)와 날개부(6a)의 접변에 해당하는 단턱부가 제1 절결선(L1)에 걸려짐으로써 서스펜션암(4)이 디스크(1)쪽으로 내려오는 힘을 구속하게 된다. 가이드홀(4a)의 제2 절결선(L2)은 자기헤드 슬라이더(2)가 디스크 표면(1)으로부터 부상높이 이상으로 부상되는 것을 방지하는 부상높이의 상한높이에 해당한다. 자기헤드 슬라이더(12)가 디스크(11) 표면에 접촉된 상태에서 디스크(1)가 회전하기 시작하면 디스크(1) 표면에는 유속이 발생하게 된다. 그러면 이 유속에 따른 공기유동이 자기헤드 슬라이더(2)에 수직방향으로 작용되어 공기유동은 자기헤드 슬라이더(2)의 부상력으로 나타나게 된다. 이 부상력에 의해 자기헤드 슬라이더(12)가 자체의 인가하중을 이겨내는 순간, 서스펜션암(4)은 고정부(8)를 중심으로 일정각도로 선회하여 디스크(1) 표면으로부터 올라가게 되어 F/H 스프링(6)은 상대적으로 도 6b의 상태에서 도 6a의 상태로 제2 절결선(L2) 상에 날개부(6a)와 지지부(6b)의 접변에 해당하는 단턱부가 위치하게 된다. 이 시점에서, 서스펜션암(4) 윗쪽으로 돌출된 지지부(6b)는 서스펜션암(4)에 대하여 디스크 쪽으로 인가하중을 부가함으로써 더 이상의 부상을 규제하게 된다.5 and 6, the guide hole 4a of the suspension arm 4 is set to a width of a. The first notch L1 of the guide hole 4a corresponds to the lower limit height of the height of the lift that prevents the magnetic head slider 2 from contacting the disk surface 1. When the recording operation is completed and the disk 1 is stopped, the magnetic head slider 2 will be brought into contact with the surface of the disk 1 by the applied load of the suspension arm 4. At this time, the suspension arm 4 pivots about the fixing part 8 at an angle and descends toward the disc 1, and the F / H spring 6 is relatively in the state of FIG. 6A in the state of FIG. 6B. It extends toward the head slider 2. At some point when the suspension arm 4 descends toward the disc, the stepped portion corresponding to the contact between the support part 6b and the wing part 6a is caught by the first notch line L1 so that the suspension arm 4 becomes the disc 1. You will be constrained to come down toward The second notch L2 of the guide hole 4a corresponds to the upper limit height of the height of injury, which prevents the magnetic head slider 2 from rising above the height of the injury from the disk surface 1. When the disk 1 starts to rotate while the magnetic head slider 12 is in contact with the surface of the disk 11, a flow velocity is generated on the surface of the disk 1. Then, the air flow according to this flow rate is applied to the magnetic head slider 2 in the vertical direction so that the air flow appears as the floating force of the magnetic head slider 2. As soon as the magnetic head slider 12 overcomes its applied load by this floating force, the suspension arm 4 is pivoted at a predetermined angle about the fixed portion 8 to rise from the surface of the disk 1 so that F The / H spring 6 has a stepped portion corresponding to the contact between the wing portion 6a and the support portion 6b on the second notch L2 in the state of FIG. 6B in the state of FIG. 6B. At this point, the support 6b protruding upwards of the suspension arm 4 regulates further injury by applying an applied load toward the disc with respect to the suspension arm 4.

결과적으로, 본 발명에 따른 자기헤드 지지장치는 소정 탄성력을 갖고 서스펜션암(4)의 아래쪽과 윗쪽에 교차하여 걸쳐진 F/H 스프링(6)에 의해 종래의 CSS 동작을 배제하여 항상 부상높이 내에서 부상한채 디스크(1)의 정보 기록면에 억세스함으로써 억세스타임을 향상시키게 된다. 또한, 정보 기록에 있어서 일정 허용범위 내에서 부상높이를 유지시킴으로써 정확하게 정보를 기록할 수 있음은 물론 서스펜션암(4)의 강성을 보강하여 진동에 강한 특성을 갖게 된다.As a result, the magnetic head support device according to the present invention has a predetermined elastic force and always excludes the conventional CSS operation by the F / H springs 6 intersecting the upper and lower sides of the suspension arm 4 so as to always maintain the height within the lift height. Access time is improved by accessing the information recording surface of the disc 1 while floating. In addition, in the information recording, by maintaining the height of the lift within a certain allowable range, it is possible to accurately record the information, as well as to reinforce the rigidity of the suspension arm 4 to have a strong characteristic against vibration.

상술한 바와 같이, 본 발명의 자기헤드지지장치는 자기헤드의 부상높이가 안정적으로 유지됨으로써 기록매체와 자기헤드 슬라이더 간의 접촉에 의한 흡착을 방지함은 물론, 흡착에 의한 디스크와 자기헤드 슬라이더의 손상을 방지하게 된다. 본 발명의 자기헤드 지지장치는 자기헤드를 지지하는 지지부재를 십자형 판스프링을 이용하여 기록매체로부터 일정 높이의 부상높이를 유지함으로써 CSS 과정을 생략하여 신속한 억세스타임으로 기록매체에 억세스하게 된다. 나아가, 본 발명의 자기헤드 지지장치는 자기헤드를 지지하는 지지부재의 부상 및 하강을 일정 허용범위 내에서 규제함으로써 우수한 부상특성을 갖게 된다.As described above, the magnetic head support apparatus of the present invention maintains the height of the magnetic head stably, thereby preventing adsorption due to contact between the recording medium and the magnetic head slider, as well as damaging the disk and the magnetic head slider due to the adsorption. Will be prevented. In the magnetic head support apparatus of the present invention, the support member for supporting the magnetic head is maintained by using a cross-shaped leaf spring to maintain a certain height of elevation from the recording medium, thereby accessing the recording medium with rapid access time by eliminating the CSS process. Furthermore, the magnetic head support device of the present invention has excellent floating characteristics by regulating the rise and fall of the support member for supporting the magnetic head within a certain allowable range.
