ABSTRACT OF THE DISCLOSURE A multi-channel magnetoresistance effect type magnetic head has a short wavelength region magnetic head element and a relatively longer wavelength region magnetic head element. The two head elements are provided on a magnetic substrate with each having a magnetic circuit containing a magnetic gap facing a surface adjacent to and across from a magnetic recording medium. Each magnetic circuit has a discontinuity portion with a bridging magnetoresistance effect sensing element to magnetically connect the discontinuity portion. The longer wavelength magnetic head discontinuity portion is spaced at a greater distance from the adjacent surface than is the discontinuity portion of the shorter wavelength magnetic head element.
