MAGNETIC RECORDING METHOD AND DEVICE THEREFOR, AND DEVICE FOR DISCRIMINATING COERCIVE FORCE OF MAGNETIC RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To write the magnetic information into a magnetic recording medium by a discriminated appropriate writing current which is discriminated for the magnetic recording medium.;SOLUTION: In this device, when a current value suitable for the write-in to the magnetic recording medium is obtained, the coercive force of the magnetic recording medium is obtained from a voltage at the read out time of the magnetic information written into the magnetic recording medium and the transportation amount of this magnetic recording medium, then the current value corresponded to this coercive force is obtained.;COPYRIGHT: (C)2005,JPO&NCIPI
