Patent ID: 7813085

Claim:
A thin-film magnetic head comprising: a magnetoresistive element for reading data, comprising a lower shield layer and an upper shield layer provided so as to sandwich a magnetoresistive multilayer therebetween, one of edges of each of the upper and lower shield layers reaching a head end surface on an air bearing surface side; and an electromagnetic transducer for writing data, comprising a main magnetic pole layer and an auxiliary magnetic pole layer, one of edges of each of the main and auxiliary magnetic pole layers reaching the head end surface, at least one laminate shield layer for tolerating an external magnetic field, provided adjacently through a non-magnetic material on one side or on both sides in a track width direction of at least one layer out of said lower shield layer, said upper shield layer and said auxiliary magnetic pole layer, and one edge of said at least one laminate shield layer reaching the head end surface.
