硬盘记录信息可视化检测威廉希尔官方网站

硬盘记录信息可视化检测威廉希尔官方网站 ：提出一种基于软件实现的硬盘记录信息可视化检测威廉希尔官方网站 。该威廉希尔官方网站 可以精确定位到特定磁道，从硬盘控制电路有关测试点采集未经磁头读写通道处理的原始电磁信号，经滤波处理，按电磁公式由电磁信号推导出硬盘盘片表面磁场强度分布情况，最后以图像形式实时反映这一情况，完成对硬盘记录信息的可视化检测。

Abstract：A technology to visually detect hard disk record information is proposed．This technology first makes an exactly location on the specified track，collects original electromagnetic signal which hasn’tbeen processed by head’S reading／writing channel，through the test points on hard disk’S control circuit，processes the data with a data filter algorithm ，deduces the magn etic distributing intensity data from the electromagn etic data according to the relative electromagnetic form ula， then presents the magnetic intensity data in a image form real—timely，by this way，the visual detection to the hard disk’S recording inform ation was achieved．
