A magnetic recording and reproducing apparatus includes a separator and first and second amplifiers. The separator separates a servo data signal and a user data signal, both reproduced by a reproducing head. The first and second amplifiers are connected to the output stage of the separator to increase the amplitude ratio of the servo data signal to the user data signal. The magnetic recording and reproducing apparatus can precisely decode the servo data along with the user data, and can achieve a highly precise servo control.
