Claim:
1. A magnetic recording and reproducing device, comprising: a magnetic recording medium including a first track including a magnetic head including a recording unit and a reproducing unit, the recording unit recording information in the magnetic recording medium, the reproducing unit reproducing the information recorded in the magnetic recording medium, the recording unit including the reproducing unit including a reproducing element having a reproducing width along the second direction, the first track including a plurality of first recording symbols, the first sub-track including a plurality of first magnetic recording components, the second sub-track including a plurality of second magnetic recording components, one of the first recording symbols being formed of one of the first magnetic recording components and one of the second magnetic recording components, the one of the first magnetic recording components having a first magnetization, the one of the second magnetic recording components having a second magnetization, the magnetic head setting the first magnetization and the second magnetization to a first state when information to be written to the one of the first recording symbols is a first value, the magnetic head setting the first magnetization and the second magnetization to a second state when the information to be written to the one of the first recording symbols is a second value, the magnetic head setting one of the first magnetization or the second magnetization to the first state and setting one other of the first magnetization or the second magnetization to the second state when the information to be written to the one of the first recording symbols is a third value, the reproducing width being not less than 1.2 times a side gap along the second direction between the magnetic pole and the side shield.
