无论电脑中的硬盘,还是硬盘类 DV 内置的 HDD,采用的都是温彻斯特技术,磁头悬浮于高速旋转的盘片之上。所以,对工作环境要求较高,不能有过于强烈的震动和冲击。外力冲击或大幅度机震对于传统的磁带式 DV 而言并不是大问题,但硬盘类 DV 则必须正视。各大厂商一般采用两类技术来确保硬盘在使用中的安全。首先将硬盘安装于物理结构的减震器上,形成悬浮状态,减小震动对硬盘的冲击。另外机内增设震动传感器,能够实时感知运动的幅度与速度,一旦超过限定,震动传感器将使硬盘磁头复位,以免损伤。然而在磁 Regardless of the hard disk in the computer, or hard disk DV built-in HDD, using Winchester technology, the head suspended in high-speed rotating disk above. Therefore, higher requirements for the working environment, can not have too strong a shock and impact. External impact or large machine shock for the traditional tape-based DV is not a big problem, but the hard disk DV must look squarely. Major manufacturers generally use two types of technology to ensure the safety of the hard disk in use. First of all, the hard disk is installed on the shock absorber of the physical structure to form a floating state, so as to reduce the impact of vibration on the hard disk. In addition, an additional vibration sensor inside the machine, real-time perception of the magnitude and speed of movement, once the limit is exceeded, the vibration sensor will reset the hard disk head, so as not to damage. However, in the magnetic
