Abstract:
A disk memory device comprising:a head which reads a data recorded on a disk and outputs a read-out signal;an A/D converter which converts the read-out signal into a digital signal; anda signal processing circuit of a multilayer perception type neural network scheme which receives the digital signal converted by said A/D converter,wherein said signal processing circuit has an input layer which inputs the digital signal, a hidden layer having a plurality of hidden nodes, and an output layer which outputs an output signal, andsaid input layer has an adding circuit which outputs a plurality of signals, and said hidden layer has a weighting arithmetic circuitry which is shared by each of said plurality of hidden nodes, calculates a coupling weighting coefficient between said input layer and said plurality of hidden nodes, and outputs a result thereof to said output layer.
