MAGNETIC RECORDING MEDIUM, ITS MANUFACTURING METHOD AND MAGNETIC RECORDER USING THE MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a magnetic recording medium for high density recording. SOLUTION: In the magnetic recording medium 5, an inorganic compound film 2 being a seed layer, a magnetic film 3 on which information is recorded and a protective film 4 are laminated on a substrata 1. The inorganic compound film 2 has cylindrical crystalline particles 6 and amorphous grain boundary phases 7 partitioning the particles 6. In the magnetic film 3, magnetic particles 14 are arranged and epitaxially grow on the inorganic compound film 2, so that the particle size and the standard deviation of the inorganic compound film 2 are reflected on the magnetic particles 14 of the magnetic film 3.
