PROBLEM TO BE SOLVED: To provide a signal processing method and a magnetic recording and reproducing device not generating discrimination errors due to sub-pulses when reproducing the signals recorded by magnetic transfer on a magnetic recording medium. SOLUTION: If there is a space 44 of 3 bits or larger between the continuous magnetic bits 42 when the magnetic head reads the signals of magnetic information bits 42 recorded by magnetic transfer along the tracks on a magnetic recording medium 2, the signals read from the sub-pulse area F within the space 44 are invalidated when reading the magnetic bits 42 along the tracks. This device does not read these signals or does nor process the reading as the effective signals even if it reads. COPYRIGHT: (C)2006,JPO&NCIPI
