MAGNETIC RECORDING MEDIUM AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To furthermore increase the linear recording density of a patterned medium having recording tracks each consisting of arrayed single magnetic domain minute recording parts. SOLUTION: This magnetic recording medium is constituted of the recording tracks each consisting of plural arrayed single magnetic domain minute recording parts 3 formed on a substrate 1 and nonmagnetic bodies (parts 4 to be unrecorded) formed between the adjacent parts 3. Each of the parts 3 is made from a magnetic alloy containing Sm-Co so that the inequality: W/L>1 (wherein W is the length of the part 3 in a direction that the recording track orthogonally crosses; L is the length of the part 3 in the extended direction of the recording track) is satisfied and the direction of the easily magnetized axis of the part 3 is almost coincident with the extended direction of the recording track.
