Abstract :
In this correspondence we consider the coding for multitrack magnetic recording systems. We provide analytical results related to uncoded and coded multitrack systems which constitute the basis of the code construction. We have designed matched spectral null codes for multitrack recording systems which give coding gains from 3 to 4.8 dB over uncoded systems
