在這些應用里，電腦磁碟讀取頭應該是最具技術挑戰性的。Because read heads based on emr use nonmagnetic materials, they would not suffer from magnetic noise limitations
由於emr讀取頭用的是非磁性材料，所以不會受到磁雜訊的限制。Most, if not all, of the magnetic disk drives used in today ' s computers employ gmr read - head sensors to detect the magnetic bits of stored information
現在，絕大多數電腦里的磁碟機，是用gmr的讀取頭來偵測儲存資訊的磁位元。Disk drives have three key components : the magnetic disk medium, which stores the information, the write - head element, which writes information onto the disk, and the read - head element, which reads the information
