The heat assisted magnetization reversal scheme has been proven to be effectively reduces threshold field down to 90 %. Otherwise, this field doesnĄ¯t depend on heating time. To understand a read-write information process, cooling time dependence of threshold field has been evaluated. As a result, the threshold field depends on the cooling time and become constant after 300 ps. This result corresponds to data transfer of Hard Disc Drive about 30 Gb/s. %K magnetic recording %K PMA %K heat assisted %K threshold field %K heating time and cooling time %U http://iptek.its.ac.id/index.php/jts/article/view/64/55
