CPU, ROM, 보이스 코일 모터, 변화된 옵셋력의 값을 업데이트하는 RAM등으로 이루어진 하드 디스크 드라이브에서 캘리브레이션 루틴에 하드 디스크의 제로 트랙에서 맨끝 트랙까지 탐색하여 각 트랙의 옵셋력을 측정한 다음에 이 값을 RAM에 저장는 옵셋력 측정 루틴을 삽입하여 변화되는 옵셋력을 교정하도록 하는 보이스 코일 모터의 옵셋력 조절 방법.On a hard disk drive consisting of a CPU, ROM, voice coil motor, and RAM that updates the value of the changed offset force, the calibration routine searches for zero to the last track on the hard disk, then measures the offset force of each track. The method of adjusting the offset force of the voice coil motor to insert the offset force measurement routine into the RAM to correct the change of the offset force. CPU, ROM, 보이스 코일 모터등으로 된 하드 디스크 드라이버에 있어서, CPU의 제어에 의하여 초기 고정된 옵셋력을 ROM으로 부터 옮겨 받아 CPU내의 프로그램 실행에 의하여 새로운 옵셋력의 값을 저장하는 RAM을 더 포함하는 보이스 코일 모터의 옵셋력 조절 장치.In a hard disk drive including a CPU, a ROM, and a voice coil motor, the CPU further includes a RAM that transfers an initial fixed offset force from the ROM under the control of the CPU and stores a new offset force value by executing a program in the CPU. Offset force adjusting device of voice coil motor. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
