Abstract
A magnetic recording system for recording information on a magnetic recording medium magnetized with a perpedicular magnetization component by a magnetic recording head so as to be reproduced by a magnetic reproducing head, the magnetic recording head including a leading side and a trailing side opposite to the leading side, the leading side leading the trailing side in terms of motion relative to the magnetic recording medium, the magnetic recording head generating a first magnetic field with a field strength from the leading side to the magnetic recording medium, and generating a second magnetic field from the trailing side to the magnetic recording medium, a field strength of the second magnetic field being smaller than that of the first magnetic field.
