发明名称 RECORDING/REPRODUCING SEPARATION TYPE MAGNETIC HEAD
摘要 PROBLEM TO BE SOLVED: To provide a recording/reproducing separation type magnetic head in which protrusion of a reproducing head element to a floating plane by heat deformation caused by variation of environmental temperature can be reduced. SOLUTION: This recording/reproducing separation type magnetic head is provided with a magneto-resistance effect type head 11 having a magnetic resistance effective film 25 and a pair of electrodes 26 connected electrically to the magneto-resistance effect film 25 between a lower part shield 23 and an upper part shield 28 provided on a substrate 21, and an induction type thin film magnetic head 12 having a coil 33 between a lower part magnetic pole 31 and an upper part magnetic pole 35 provided on an upper part shield 28 of the magneto-resistance effect type head 11 through a separation film 29 through a magnetic gap film 32 and an inter layer insulation film 34. And the sum of film thickness of the lower part shield 23 and film thickness of the upper part shield 28 is set to 0.4μm or more to less than 3.4μm. COPYRIGHT: (C)2004,JPO&NCIPI
