硬盤記錄信息可視化檢測技術：提出一種基于軟件實現的硬盤記錄信息可視化檢測技術。該技術可以精確定位到特定磁道，從硬盤控制電路有關測試點采集未經磁頭讀寫通道處理的原始電磁信號，經濾波處理，按電磁公式由電磁信號推導出硬盤盤片表面磁場強度分布情況，最后以圖像形式實時反映這一情況，完成對硬盤記錄信息的可視化檢測。
關鍵詞：硬盤記錄信息；可視化檢測；圖像形式

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．
Key words：Hard Disk Record Inform ation；Visual Detection；Image
