Abstract:
A merged head device, comprising:a slider main body having an air bearing surface to a magnetic medium;two magnetic shield films disposed parallel on a common plane, spaced apart at a predetermined interval and orthogonal to a direction of air flow on a downstream side of said air bearing surface of said slider main body;a magnetoresistive effect head disposed through a magnetic separating layer of an insulator between said two magnetic shield films;an inductive head consisting of a first magnetic pole film corresponding to one of said two magnetic shield films located on said downstream side and a second magnetic pole film disposed through a magnetic gap on said downstream side of said first magnetic pole film wherein recording is effected by a magnetic field generated at said magnetic gap; andconcave portions within said common plane on each of two sides parallel to said direction of air flow of said second magnetic pole film along said direction of air flow which define a width of said second magnetic pole film;wherein said concave portions are filled with a non-magnetic material, such that particles, such as dust, are unable to accumulate within said concave portions.
