Abstract
Described are systems, devices and methods for staggered bits magnetic recording. A staggered bits track pattern is recorded on granular magnetic recording media, thereby mapping a data bit sequence onto adjacent tracks so that the bits in one track are staggered relative to the bits in the adjacent track. A read head having an effective cross-track width extending across the tracks is aligned to read a sequence of combined bit signals as the read head is advanced in the down-track direction. Each combined bit signal combines one bit from each adjacent track. A data channel coupled to the read head is used to disambiguate the sequence of combined bit signals, thereby reproducing the data bit sequence.
