Magnetic head having a read element upper shield film and a write element lower magnetic film separated by a non-magnetic film having a thickness such that magnetic coupling is enduced therebetween

A combined type thin film magnetic head comprising:

• a magnetoresistive conversion element including a magnetoresistive film, a first magnetic shield film and a second magnetic shield film with said first magnetic shield film and said second magnetic shield film provided at either side of said magnetoresistive film;
• and
• an inductive conversion element being provided with a thin film magnetic circuit constituted with a first magnetic film, a coil film supported by an insulating film, a second magnetic film and a gap film, and being combined with said magnetoresistive conversion element with said first magnetic film placed as if to be adjacent to said second magnetic shield film, said first magnetic film and said second magnetic shield film are separated from each other by a non-magnetic film with a film thickness of said non-magnetic film selected at a value such that magnetic coupling is induced between said second magnetic shield film and said first magnetic film and said first magnetic film is provided with a first pole portion with a width thereof set smaller than a width of said second magnetic shield film, and a saturation magnetization of said first magnetic film is higher than a saturation magnetization of said second magnetic shield film, wherein
• said saturation magnetization of said second magnetic shield film is less than 10 kGauss;
• and
• said saturation magnetization of said first magnetic film is at or more than 10 kGauss.
