Research Abstract

As a signal processing system for the next-generation hard disk drive in which ultra-high density recording of more than 2Tb/in^2(2 trillion bits per square inch) is required, the two-dimensional signal processing system is studied. A two-dimensional neural network equalizer as the two-dimensional signal processing system for ultra-high density magnetic recording is developed. It is shown that the equalizer can attain 4Tb/in^2 which the conventional one-dimensional linear equalizer cannot achieve.
