Abstract:
A giant magnetoresistive transducer for reading data signals recorded on a surface of a magnetic medium, said transducer having an air bearing surface comprising:a giant magnetoresistive sensor having a sensing surface and side surfaces, said sensor being recessed at a distance S from said air bearing surface to define a gap between said sensor and said air bearing surface;magnetic shield members spaced from each of said side surfaces and at a distance G between said shield members wherein said distance S is less than half of said distance G for preventing signal loss caused by said shields shunting away incoming transition flux from said magnetic medium; anda dielectric layer disposed within said gap, said dielectric layer extending from said sensing surface to separate said sensing surface from said surface of said magnetic medium on which data signals are recorded which are to be read out by said transducer.
