MAGNETIC RECORDING MEDIUM, ITS MANUFACTURING METHOD, AND MAGNETIC STORAGE

摘要

A magnetic recording medium(100)comprises a substrate(1),a soft magnetic layer(3),a seed layer(5),and a recording layer(6)having an artificial lattice structure,all layers being provided on the substrate.The seed layer(5)is formed of Pd and one element selected from the group consisting of Si,B,C,and Zr.Therefore,the magnetic exchange coupling force parallel to the recording layer(6)can be weakened.Small recording magnetic domains are formed in the recording layer(6),magnetization transition regions become clear,and noise is reduced.Even if information is recorded at high density,the information can be reproduced with low noise.A magnetic storage having such a magnetic recording medium can achieve a surface recording density of 150 gigabits/square inch.
