MAGNETIC RECORDING MEDIUM AND MAGNETIC RECORDING DEVICE

摘要

PROBLEM TO BE SOLVED: To improve the contamination resistance of a substrate and to reduce the cost of a magnetic recording medium having high recording density with respect to a magnetic recording medium and a magnetic recording device. SOLUTION: An alkali metal stopper layer 3 such as a diamond like carbon film or the like is formed between the substrate 1 and a magnetic layer 5.
