A magnetic recording and reproducing apparatus extracts a record signal from a sum signal (ADD) of signals detected via first and second magnetic detection regions (RH 1, RH 2 ) that are formed to be offset in the lengthwise (T<SUB>L</SUB>) and widthwise (T<SUB>W</SUB>) directions of a recording track having an overlapping part in the widthwise direction (T<SUB>W</SUB>), and extracts servo information from a sub signal (SUB).
