ABSTRACT:
A micro mark on a magnetic recording medium is reproduced in a signal reproducing apparatus by causing a magnetic wall to move on the recording medium. A partial temperature profile is applied on the medium by a heating device which is adapted to be movable relative to the medium. A reproducing device generates a first reproduction signal containing a signal component due to a first magnetic wall movement from a front side of a temperature peak position in the temperature profile toward the temperature peak position and a signal component due to a second magnetic wall movement from a rear side of the temperature peak position toward the temperature peak position. The signal component due to the second magnetic wall movement is reduced in the reproduction signal so as to generate a second reproduction signal which mainly contains the signal component due to the first magnetic wall movement.
