Claim Text:
1. A magnetic recording and reproducing device, comprising: a magnetic recording medium including a first track including a recording unit recording information in the first sub-track and the second sub-track; and a reproducing unit reproducing the information recorded in the first sub-track and the second sub-track while opposing the first sub-track, the second sub-track, and a boundary between the first sub-track and the second sub-track, the first sub-track including a plurality of first magnetic recording components, the first magnetic recording components including a first component and a second component, the second component being adjacent to the first component in the first direction, the second sub-track including a plurality of second magnetic recording components, the second magnetic recording components including a third component and a fourth component, the third component being adjacent to the first component in the second direction, the fourth component being adjacent to the third component in the first direction and adjacent to the second component in the second direction, a first recording symbol being formed of the first component and the third component, a second recording symbol being formed of the second component and the fourth component, the information recorded in the first recording symbol being a first value when a magnetization of the first component is in a first state and a magnetization of the third component is in the first state, the information recorded in the first recording symbol being a second value when the magnetization of the first component is in a second state and the magnetization of the third component is in the second state, the information recorded in the first recording symbol being a third value when the magnetization of the first component is in the first state and the magnetization of the third component is in the second state, the information recorded in the second recording symbol being the third value when a magnetization of the second component is in the second state and a magnetization of the fourth component is in the first state.
