PURPOSE:To obtain excellent recording an reproducing characteristic even for a high coercive force magnetic recording medium by providing triangular grooves in the vicinity of the an operating gap of high magnetic permeability ferrite cores, burying magnetic alloy films into a groove, and making the track width narrower than the maximum width of the magnetic alloy film core. CONSTITUTION:A magnetic core is constituted of magnetic alloy films 32, 32' and high magnetic permeability ferrite 30, 30'. Triangular grooves 31, 31' are provided in the vicinity of the operating gap 35 of high magnetic permeability ferrite 30, 30'. The magnetic alloy films 32, 32' are buried in the grooves 31, 31'. Above-mentioned magnetic alloy films are placed opposite to each other through the operating gap 35, and the track width is made narrower than the maximum width of magnetic alloy films 32, 32'. Thus, a narrow track magnetic head having excellent recording and reproducing characteristics and suitable for mass production can be obtained.
