Claims

[Scope of utility model registration request]

A recording head having a constant track width W and a track width R set to be juxtaposed to the recording head and wider than the track width W of the recording head so that the signal number recorded by the recording head can be followed and reproduced. The recording head and the reproducing head are arranged such that the center of the track of the recording head and the center of the track of the reproducing head substantially coincide, and the track width R of the reproducing head is The track width W of the recording head and the reproduction head are adjusted so that the value obtained by subtracting the track width W of the recording head and dividing by 2<RW) is greater than or equal to the tolerance δ of the positional deviation between the magnetic recording medium and the recording and reproduction head. A magnetic head device characterized in that the track width R of the head is set.
