PURPOSE:To make high-density recording possible by making respective magnetization directions of adjacent tracks nonparallel with each other and utilizing the inclination loss effect of a gap to eliminate the crosstalk which is caused when tracks are recorded close adjacently to one another. CONSTITUTION:An annular recording track band 3 is formed in the outside circumferential part near the circumferential edge on a magnetic disc 1 rotated around a rotation center O. A guard band is not formed between a recording track A and a recording track B adjacent to each other, and they are recorded close adjacently to each other. A magnetic head having a gap which intersects obliquely the radial direction of the magnetic disc, and thereby, the recording direction intersect obliquely the direction orthogonal to the breadthwise direction of tracks. That is, tracks A and B are so recorded that respective magnetization direction are not parallel with each other. Consequently, information on the adjacent track B does not interfere with information of the track B when information of the track A is reproduced; and even if it interferes with information of the track A, this interference appears as only a weak signal related to cosine components of the angle made between respective magnetization directions. |
