WebExpert Answer. A flat Al2O3 - TiC read-write head surface contacts a thin-film magnetic computer hard disc with characteristics given by Bhushan (1999). Using the values … GMR head has inherited the reading and writing technology in TFI head and AMR head, but it is more sensitive than the former. The GMR head is composed by 4 layers of conductive materials and magnetic thin materials. The GMR sensor owns high sensitivity than the AMR head. Thus it can improve the density … See more The conventional head is electromagnetic head which combines the read and write function together. The magnetoresistive ( MR ) head owns detachable head structure. The writing … See more Hard disk adopts the TFI read/write technology from 1990 to 1995.
