By the head guiding means provided to prevent contact between the head and the disk surface in the process of seating the head on the surface, it is possible to prevent a change in the viscosity of the surface material formed on the surface of the disk media, thereby preventing an error during reproduction of the recorded data. It is to provide a hard disk drive that can improve the data retention characteristics.

상기와 같은 목적을 달성하기 위한 본 발명의 특징은 서보모터 구동으로 디스크가 회전되거나 정지시 헤드가 디스크로부터 플라잉되거나 안착되도록 헤드스택 및 디스크 어셈블리로 형성된 하드디스크 드라이브에 있어서, 상기 헤드스택 어셈블리에 디스크 정지시에는 헤드를 받쳐주고 동작시에는 헤드로 부터 이탈되게 보조로드아암을 설치한 것이다.A feature of the present invention for achieving the above object is a hard disk drive formed of a head stack and a disk assembly so that the head is flying or seated from the disk when the disk is rotated or stopped by the servo motor drive, the disk in the head stack assembly The auxiliary rod arm is installed to support the head when stopped and to move away from the head during operation.

이하, 본 발명에 의한 하드디스크 드라이브를 첨부도면을 참조하여 구체적으로 설명하면 다음과 같다.Hereinafter, a hard disk drive according to the present invention will be described in detail with reference to the accompanying drawings.

제2도는 본 발명에 의한 하드디스크 드라이브를 도시한 것으로 (a)는 하드디스크 드라이브의 요부 구성을 나타낸 정면도이고, (b)는 헤드와 디스크의 구동관계를 설명하기 위한 도면으로서, 자기기록 재생 장치에 사용되는 하드디스크 드라이브의 헤드와 디스크가 접촉되어 서보모터 구동으로 디스크가 회전되거나 정지시에 헤드가 디스크에서 플라잉되어지거나 안착되도록 헤드스택 어셈블리에 아암어셈블리가 설치되고 단부에 대향되는 헤드가 장착된 서스펜션이 아암어셀블리에 설치되며, 서브모터 구동으로 회전 및 정지되는 디스크를 탑재시키는 디스크 어셈블리로 이루어진 하드디스크 드라이브에 있어서, 헤드 (5) (10)가 장착되는 헤드스택 어셈블리(1)에 디스크(6)가 회전 및 정지단계에 진입하게 되는 경우에는 단부에 헤드(5) (10)가 장착된 서스펜션(3)을 받쳐주고, 디스크(6)의 정상적인 회전 궤도에 진입하면 디스크(6)상의 헤드(5) (10)로 부터 이탈되어 복귀되는 보조로드아암(8)을 설치하되, 상기 보조로드아암(8)은 디스크(6)의 회전상태에서 헤드(5)(10)가 서서히 미끄러져 안정된 동작으로 플라잉되도록 단부가 라운딩가공된 것이며, 아암어셈블리(2)가 헤드스택 어셈블리(1)에 연결된 방식과 동일하게 전기적 메카니즘의 MOS 집적회로를 이용하여 구동되도록 형성된 것이다.2 shows a hard disk drive according to the present invention, (a) is a front view showing the main structure of the hard disk drive, and (b) is a view for explaining the driving relationship between the head and the disk. The arm assembly is installed on the headstack assembly and the head facing the end is mounted so that the head of the hard disk drive is used to contact the disk and the disk is rotated or driven by the servomotor when the disk is rotated or stopped. A hard disk drive comprising a disk assembly for mounting a disk mounted on an arm assembly and rotating and stopped by driving a submotor, wherein the disk (in the head stack assembly 1 to which the heads 5 and 10 are mounted) In case 6) enters the rotation and stop phase, the head is equipped with heads 5 and 10 at the end. Supporting the pension (3), and enters the normal rotational track of the disk (6) installs the auxiliary rod arm (8) which is separated from the head (5) 10 on the disk (6) and returned, The arm 8 is rounded at the end so that the heads 5 and 10 slide slowly in a rotational state of the disk 6 and fly in a stable motion. The arm assembly 2 is connected to the head stack assembly 1. It is formed to be driven using the MOS integrated circuit of the electrical mechanism in the same way.

상기와 같이 형성된 본 발명에 의한 하드디스크 드라이브는 데이터의 처리시 또는 종료되어 디스크의 동작을 정지하게 될때에는 디스크 어셈블리(7)에 의해 디스크(6)의 회전상태에서 보조로드아암(8)은 "가"위치에서 가상선으로 도시된 "나"위치로 이동하면서 헤드(5)(10)의 서스펜션(3)을 받쳐주게 되어 디스크(6)로 부터 이격됨에 따라 디스크(6)의 회전은 정지되어지는 것이다. 그리고 디스크(6)의 회전이 일정속도 이상으로 정상궤도로 회전되면 헤드(5)(10)를 받쳐준 보조로드아암(8)은 "가"위치로 복귀되어지는 것이다.When the hard disk drive according to the present invention formed as described above is terminated when the data is processed or the operation of the disk is stopped, the auxiliary rod arm 8 is rotated by the disk assembly 7 in the rotation state of the disk 6 " From the position "A" to the position "I" shown as a virtual line, the support of the suspension 3 of the heads 5 and 10 is spaced apart from the disk 6 and the rotation of the disk 6 is stopped. To lose. When the rotation of the disk 6 is rotated to the normal orbit over a certain speed, the auxiliary rod arm 8 supporting the heads 5 and 10 is returned to the "ga" position.

이상에서와 같이 본 발명의 하드디스크 드라이브는 헤드와 디스크가 접촉되어 서보모터의 구동으로 헤드가 디스크에서 플라잉되어지거나 안착될때 헤드스택 어셈블리에 장착된 보조로드아암에 의해 헤드와 디스크의 접촉을 방지하므로, 디스크 미디어 표면물질의 점도변화에 영향을 주지않아 데이터의 재생시 에러발생을 줄이며, 헤드와 디스크표면의 손상을 방지하여 데이터를 장시간동안 보관할 수 있다.As described above, the hard disk drive of the present invention prevents the head and the disk contact by the auxiliary rod arm mounted on the head stack assembly when the head and the disk is in contact with the drive of the servo motor when the head is flying or seated in the disk. In addition, it does not affect the viscosity change of the disk media surface material, thereby reducing the occurrence of errors during data reproduction, and prevents damage to the head and the surface of the disk, so that the data can be stored for a long time.
