DESCRIPTION:Because conventional perpendicular recording is now reaching i
 ts useful limits\, the hard drive industry is heavily invested in several 
 alternative recording technologies. The majority of these configurations (
 such as heat-assisted magnetic recording\, microwave-assisted magnetic rec
 ording\, and bit-patterned magnetic recording) secure their advantages by 
 solving essential problems in the writing process. In contrast\, two-dimen
 sional magnetic recording (TDMR) expends its essential focus on the readin
 g process\, by providing multiple looks at adjacent written information vi
 a multiple read sensors on one slider. This “sleeper” technique was ra
 ther abruptly recognized\, at a recent conference of recording technologis
 ts\, as a leading contender for the next generation of HDD technology. Whi
 le generally thought of as a more conventional option than the alternative
 s\, TDMR nevertheless has profound impact on magnetic component design and
  on elements of the entire supporting recording system. These impacts will
  be reviewed in detail from both a magnetic system and a signal-processing
  perspective. Innovations in linear and nonlinear syste
