Characteristics of crosstalk in the reproduced output of a newly developedmulti-channel MR head

We prepared the multi-channel magnetoresistive head with a simple structura l design and it has the advantages of high-density recording and ultra-high transfer rate. Characteristics of crosstalk in the reproduced output of ou r head have been estimated by a micromagnetic calculation using the Landau- Lifshitz-Gilbert (LLG) equation, while the specimen head was fabricated and evaluated. As a result, by applying a magnetic field of 40 Oe only between adjacent channels, the crosstalk was much decreased without reducing the r eproduced output. (C) 2001 Elsevier Science B.V.
