To explore the possibility for ultra-high areal density recording, submicron-trackwidth inductive-write/magnetoresistive-(MR)-read composite heads were fabricated. The focused ion beam etching technique was applied to fabricate a approximately 1- mu m-wide write-track completely aligned to the read-...
