Claims

[Scope of utility model registration request]

In a magnetic recording and reproducing apparatus, which sequentially switches and uses a plurality of recording and reproducing heads for each track of a magnetic medium, records an FM signal on each track of the magnetic medium during recording, and reproduces the FM signal of each track during reproduction. , a phase comparator that compares the phases of the reproduction signals of the two recording and reproduction heads while the reproduction signals are simultaneously output from the two recording and reproduction heads by head switching, and a phase comparator that compares the phases of the reproduction signals of the two recording and reproduction heads, A magnetic recording/reproducing apparatus comprising: a phase shifter for matching the phase of one of the reproduction signals of the recording/reproducing head with the phase of the other.
