磁盘机在运动中,有时会划盘,将磁头浮动块和盘片的涂覆面擦伤,使设备无法继续工作。引起划盘的原因很多,但主要是尘埃、脏物侵入盘腔所致。磁盘机的通风滤尘系统向盘腔提供洁净气流不仅可以起散热作用,还可使盘腔内部保持正压,有效地阻挡了尘埃粉粒。据测试,初级滤尘器可对粒径在5～10μm 以上的尘埃起阻留作用,其余 During the movement of the disk drive, the disk may be diced occasionally to scratch the coating surface of the head slider and the disk, so that the device can not continue to work. Caused by a lot of dilemma, but mainly dust, dirt invade the disk chamber caused. Ventilation filter system disk drive system to provide clean air to the disk can not only play a cooling effect, but also to maintain a positive pressure inside the disk cavity, effectively blocking the dust particles. According to the test, the primary filter can be on the particle size of 5 ~ 10μm above the dust play a retaining effect, the rest
