PROBLEM TO BE SOLVED: To provide a magnetic recording and reproducing apparatus and a magnetic recording and reproducing method capable of stable magnetic recording and reproducing.SOLUTION: According to an embodiment, a magnetic recording and reproducing apparatus including a magnetic recording medium; a recording unit; and a reproducing unit is provided. The magnetic recording medium includes a first sub-track extending in the first direction, and a second sub-track extending in the first direction and provided side by side with the first sub-track in the second direction crossing the first direction. The recording unit records information in the first and second sub-tracks. The reproducing unit reads the recorded information. The information is a first value when the magnetization of the first sub-track and the magnetization of the second sub-track are both in a first state, is a second value when the magnetization of the first sub-track and the magnetization of the second sub-track are both in a second state, and is a third value when the magnetization of the first sub-track differs from the magnetization of the second sub-track. When the information is the third value, states of magnetic recording elements adjacent in the first direction differ from each other.SELECTED DRAWING: Figure 1 |
