Two-dimensional coding and detection for data storage on patterned media

An output signal from the magnetic force microscope is used for the detection of bit values in patterned media. In a simulated signal build of a combination of lorentzpulses the pulse distance can be changed. The two-dimensional intersymbol interference will influence the ability of the detection of the bits. Conventional detection methods are adapted for the two-dimensional situation and a comparison of this methods is made by comparing bit error rates of the detectors in the presence of noise and jitter.
