Abstract
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 (RH1, RH2) that are formed to be offset in the lengthwise (TL) and widthwise (TW) directions of a recording track having an overlapping part in the widthwise direction (TW), and extracts servo information from a sub signal (SUB).
