서보 트랙 라이터의 클록 헤드 교환장치Servo Track Writer Clock Head Changer

본 발명은 하드디스크 드라이브의 서보 트랙 라이터(servo track writer)에 관한것으로서, 특히 하드디스크 드라이브 어셈블리를 테스트하는 공정에서 사용되는 서보 트랙 라이터에 사용되는 클록 헤드(clock head) 교환장치에 관한것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a servo track writer for a hard disk drive, and more particularly to a clock head exchanger for a servo track writer used in a process of testing a hard disk drive assembly.

통상적으로 하드디스크 드라이브의 테스트고정에서 사용되는 서보 트랙 라이터에서는 블록에 클록 헤드가 설치되어 디스크의 테스트를 실시한다. 이러한 장비에 사용되는 클록헤드는 주기적으로 자주 교환해야 한다. 이러한 블록과 클록 헤드를 도 1을 참조하여 설명하면 다음과 같다.In servo trackers, which are typically used to test hard disk drives, a clock head is installed in the block to test the disk. The clockheads used in these devices need to be replaced frequently and periodically. Such a block and a clock head will be described with reference to FIG. 1 as follows.

블록(200)에는 클록 헤드(310)가 설치되는 바, 상기 헤드(310)는 블록의 일측단부분에 설치된 서스펜션(300)의 자유단에 설치된다. 이렇게 설치된 헤드는 하드디스크 드라이브의 홀에 삽입되어 디스크상을 부상하면서 디스크의 트랙을 검사한다. 이는 블록에 별도의 장치에 조립되고, 이어서 상기 장치에 의해 자동적으로 블록이 이동하는 것이다.The block 200 is provided with a clock head 310, the head 310 is installed at the free end of the suspension 300 is installed at one end of the block. The head installed in this way is inserted into the hole of the hard disk drive to inspect the track of the disk while floating on the disk. It is assembled to a separate device in the block, which is then automatically moved by the device.

이때, 상기 클록 헤드(310)가 고정된 서스펜션(300)은 블록에 별도의 나사(250) 2개를 사용하여 블록(200)에 고정하였다. 고정순서를 살펴보면, 클록 헤드(310)를 서스펜션(300)에 설치하고, 이러한 서스펜션을 블록(200)에 올려 놓은 후, 클록 헤드가 설치된 서스펜션이 움직이지 못하도록 한손으로 잡고, 이어서 인치 스크류(250) 2개를 서스펜션(300)에 올려 놓은 후, 스크류 드라이버를 사용하여 체결하는 방식이었다. 이는 조립업자가 단순하게 스크류 드라이버를 사용하여 체결한다.In this case, the suspension 300 to which the clock head 310 is fixed is fixed to the block 200 by using two separate screws 250 in the block. Looking at the fixed order, the clock head 310 is installed in the suspension 300, and the suspension is placed on the block 200, and then held in one hand to prevent the suspension in which the clock head is installed, and then the inch screw 250 After placing the two on the suspension 300, it was fastened using a screwdriver. It is fastened by the assembler simply using a screwdriver.

상기와 같은 방식이 매우 번거롭고, 불편하게 되어, 육각 스크류를 클록 블록에 부착시켜 육각 렌치를 이용함으로서, 체결을 용이하게 하였다. 그러나 이와같은 경우도 클록 헤드의 교체가 빈번하여 스크류의 헤드 육각부분의 마모로 인하여 스크류 교체 및 렌치 사용을 위해 클록 헤드 교체 데스크에서 별도의 교체작업이필요하다.The above method is very cumbersome and inconvenient, and by attaching the hexagonal screw to the clock block, the hexagonal wrench is used to facilitate the fastening. However, even in this case, the clock head is frequently replaced, and due to wear of the head hexagon of the screw, a separate replacement is required at the clock head replacement desk for screw replacement and wrench use.

상기와 같은 방식은 조립업자와 사용자에게 매우 불편하고, 이로 인하여 생산성이 저하되는 문제점이 발생하였다.Such a method is very inconvenient for the assembly company and the user, thereby causing a problem that the productivity is lowered.

First, in describing each of the drawings, only the same components have the same reference numerals as much as possible even if shown on different drawings. In describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

도 2는 본 발명의 바람직한 일실시예에 따른 서보 트랙 라이터에서 사용되는 클록 헤드 교환장치를 나타내는 사시도이다. 상기 도면을 참조하면,2 is a perspective view showing a clock head exchange apparatus used in a servo track writer according to an embodiment of the present invention. Referring to the drawings,

본 발명의 클록 헤드 서포트(10:clock head support)는 블록(20:block)에 설치함으로서, 교체작업은 클록 헤드 블록(20)에 한손으로 세트 스크류(50:set screw)를 화살표방향으로 푸쉬한 뒤, 클록 헤드가 설치된 서스펜션(40:suspention)을 블록에 끼운 후, 누른 손을 빼면 클록 헤드(clock head)가 설치된 서스펜션이 고정된다.The clock head support (10: clock head support) of the present invention is installed in the block (20: block), the replacement operation is to push the set screw (50: set screw) with one hand to the clock head block 20 in the direction of the arrow Then, after inserting the suspension (40: suspention) with the clock head in the block, the hand with the pressed head is removed to fix the suspension with the clock head (clock head).

이와같은 클록 헤드(41) 교환을 위하여 독립적인 클록 헤드 서포트(10)가 조립된다. 상기 클록 헤드 서포트(10)는 단면이 직사각형이고, 형상은 'ㄷ'형의 절곡진 모양으로서, 일측단부분(11)에는 세트 스크류(50)가 설치되고, 타측단부분(12)에는 서스펜션(40)을 조립할 수 있는 부분이 절곡된다.An independent clock head support 10 is assembled for this clock head 41 exchange. The clock head support 10 has a rectangular cross section and has a bent shape having a 'c' shape. One side end portion 11 has a set screw 50 installed therein, and the other end portion 12 has a suspension ( The part which can assemble 40 is bent.

도 3에 도시된 바와같이, 이와같은 구성에서 클록 헤드 서포트(10)는 클록 헤드 블록(20)의 단이진 면(21)에 고정핀(30)에 의해 화살표방향으로 회전가능하게 설치된다. 상기 핀(30)의 삽입위치는 서포트(10)의 세로방향의 중간정도에 삽입되어 블록의 단이진 면(21)의 중간정도에 조립된다. 따라서 상기 클록 헤드 서포트(10)가 핀(30)에 의해 조립되면, 핀(30)을 회전중심축으로 화살표방향으로 회전가능하다.As shown in FIG. 3, in such a configuration, the clock head support 10 is rotatably installed in the direction of the arrow by the fixing pin 30 on the end face 21 of the clock head block 20. The insertion position of the pin 30 is inserted in the middle of the longitudinal direction of the support 10, and assembled in the middle of the stepped surface 21 of the block. Therefore, when the clock head support 10 is assembled by the pin 30, the pin 30 can be rotated in the direction of the arrow about the center of rotation.

상기와 같은 클록 헤드 서포트(10)를 블록(20)에 조립할 경우, 사용자에 따라서 클록 헤드(41)를 교환하기 위하여 누를 때, 누루는 힘의 조절은 세크 스크류(50)를 서포트에 고정하는 위치조절로서 가능하다.When assembling the clock head support 10 as described above in the block 20, when the user presses to replace the clock head 41 according to the user, the adjustment of the pressing force is a position at which the screw screw 50 is fixed to the support. Possible as an adjustment.

이러한 세트 스크류(50:set screw)는 매우 특별한 나사로서, 바디의 내부에 압축코일 스프링이 내장된다. 스프링의 탄성력에 의해 항시 바디에 설치된 스크류가 제자리로 복귀하려는 힘이 작용한다. 즉, 클록 헤드를 교환하기 위하여 세트 스크류(50)를 누르면, 스크류부분이 들어가고, 누른 힘을 제거하면, 다시 나사부분이 복귀력에 의해 상승한다.This set screw (50: set screw) is a very special screw, the compression coil spring is built into the body. The spring force of the spring is always applied to return the screw installed in the body. That is, when the set screw 50 is pressed to replace the clock head, the screw portion enters, and when the pressed force is removed, the screw portion rises again by the return force.

결과적으로, 사용자는 서보 트랙 라이터에서, 클록 헤드를 교환하고자 할 경우, 세트 스크류의 상부를 누루고, 이어서 클록 헤드가 설치된 서스펜션을 조립하고, 누른 힘을 제거한다. 이와같이 서보 트랙 라이터에서 자주 교환해야 하는 클록 헤드를 단순한 동작으로서 용이하게 교체한다. 교체후, 클록 헤드는 하드디스크 드라이브의 내부에 위치한 디스크상을 부상하면서 디스크를 검사한다. 이러한 클록 헤드는 하드디스크 드라이브이 커버측면에 형성된 홀을 통과하여 디스크에 이른다. 검사후, 상기 하드디스크 드라이브이 내부는 진공상태로 밀폐되어 홀을 테이프로 차단하여 밀폐시킨다.As a result, when the user wants to replace the clock head in the servo tracker, he presses the upper part of the set screw, and then assembles the suspension in which the clock head is installed, and removes the pressing force. In this way, the clock head, which must be frequently replaced in the servo tracker, is easily replaced with a simple operation. After replacement, the clock head checks the disk while floating on the disk located inside the hard disk drive. This clock head passes through a hole in which the hard disk drive is formed on the cover side to reach the disk. After the inspection, the hard disk drive is sealed in a vacuum state to seal the hole with a tape.

한편, 본 발명의 상세한 설명에서는 구체적인 실시예에 관해서 설명하였으나, 본 발명의 범위에서 벗어나지 않는 한도내에서 여러 가지 변형이 가능함은 당해분야에서 통상의 지식을 가진자에게 있어 자명하다 할 것이다.On the other hand, in the detailed description of the present invention has been described with respect to specific embodiments, it will be apparent to those skilled in the art that various modifications are possible without departing from the scope of the present invention.

이상으로 살펴본 바와같이, 본 발명은 하드디스크 드라이브의 서보 트랙 라이터에서 클록 헤드를 클록 븍록에서 용이하게 교환하기에 효과적이다.As described above, the present invention is effective for easily replacing the clock head in the clock block in the servo track writer of the hard disk drive.
