ABSTRACT:
A magnetic transducer assembly for cooperating with a relatively moving magnetic recording medium to magnetically record and reproduce information on and from the magnetic recording medium. The transducer assembly comprises first and second magnetic transducers incorporated into one rail of a double-rail type slider with they are adjacent to each other. The rail has a contacting surface with a recording surface of the recording medium in recording and reproducing. The first magnetic transducer includes a first read/write core assembly having a first magnetic gap extending in directions normal to the moving direction of the recording medium and placed in a plane including the contacting surface of the rail. The second magnetic transducer includes a second read/write core assembly having a second magnetic gap which is different in length from the first magnetic gap and extends in directions normal to the moving direction thereof. The second magnetic gap is positioned in the plane including the contacting surface thereof and arranged so that its longitudinal axis is on an extension line of the longitudinal axis of the first magnetic gap.
