“…1 without guard-band, time delay devices will be necessary to match write timing between adjacent tracks, in view of the position gap between adjacent write heads on the structure. On the other hand, when using type (b), matching write timing will be easy without time delay devices, but it will need guard-band for cross-talk between adjacent cores [8]. Figure 2 shows a schematic basic system for the new coding method using type (a) in Fig.…”

A Multitrack Coding Scheme Designed for Perpendicular Recording Using Double Layer Medium and MR Head

A new multitrack coding scheme is proposed as a preferable use in perpendicular recording using a double layer medium and an MR head. The coding uses combinations of three codes in 8 orthogonal codes based on Hadamard matrix elements. The new coding method has a high code rate and reliability because of the multilevel correlation detection due to simultaneous reading of three tracks. The performances are investigated by theoretical calculations, simulations and experiments.
