PROBLEM TO BE SOLVED: To eliminate asymmetry caused by a fixed bit pattern or crosstalk from an adjacent track in a BRP-ROM system where magnetic substances are discontinuously formed according to a recording bit of information. SOLUTION: The method includes: magnetizing an average magnetization direction of each sector on the bit-patterned recording medium in a first magnetization direction, reproducing the sector and obtaining reproduction characteristics thereof as first and second reproduction characteristics (S501-S507); and magnetizing the average magnetization direction of the sector including a sector error on the bit-patterned recording medium in a direction corresponding to one of the first reproduction characteristics and the second reproduction characteristics of the sector that has better reproduction characteristics (S508-S510). Consequently, reproduction characteristics are improved. COPYRIGHT: (C)2009,JPO&INPIT
