MAGNETICALLY STABLE PARTICULATE MAGNETIC RECORDING MEDIUM HAVING HIGH SIGNAL-TO-NOISE RATIO AND METHOD OF ASSESSING MAGNETIC STABILITY OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a magnetic recording medium which comprises magnetic particles in small sizes and which is superior in magnetic stability.;SOLUTION: To provide a method of determining the coercivity ratio of the magnetic recording medium and a magnetic recording medium having a magnetizable layer of performance coercivity ratio (PCR) of at least 1.06 and preferably less than 1.4.;COPYRIGHT: (C)2004,JPO
