PROBLEM TO BE SOLVED: To provide a magnetic recording and reproducing device in which recording density of a magnetic disk can be efficiently improved, a magnetic recording method by which a record is written into the magnetic disk with high density, and a magnetic reproducing method by which the record written in the magnetic disk is read with high density. SOLUTION: In the magnetic recording and reproducing device performing recording and/or reproducing of information signals for the magnetic disk, the device is provided with: a spindle motor rotatively driving the magnetic disk; a plurality of recording heads forming recording bits on the magnetic disk, performing recording of the information signals, and having azimuth angles being different from one another; a plurality of reading heads performing reading of the information signals recorded in the magnetic disk; a head feeding mechanism for scanning the recording head and the reading head; an amplifying part amplifying the information signal recorded and reproduced by the recording head and/or the reading head; an A/D converter A/D-converting the information signal; and a re-constitution part of recording data.
