MAGNETIC RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a magnetic recording medium which is excellent in sliding resistance and in corrosion resistance and which is capable of recording and reproducing with a high surface recording density of≥600 Gbits/square inch. SOLUTION: In a disk-shaped magnetic recording medium of a magnetic recording system recorded with the surface recording density of≥600 Gbits/square inch is provided with a protective layer comprising tetrahedral-based amorphous carbon. The sliding resistance and the corrosion resistance are improved even under the condition of the high surface recording density of≥600 Gbits/square inch. COPYRIGHT: (C)2005,JPO&NCIPI
