Abstract
A magnetic recording and reproducing apparatus is disclosed which includes: a recording device configured to record with a write head a plurality of tracks constituting a unit of signal processing for data detection, to magnetic recording media; a reproduction device configured to reproduce with a read head a plurality of reproduction signals concurrently from the plurality of tracks on the magnetic recording media in different positional relations to the tracks, the reproduction signals being arranged into that one unit for signal processing thereby generating the track-specific reproduction signals; and a phase alignment device configured to align phases of record signals between adjacent tracks among the plurality of tracks recorded by the recording device to the magnetic recording media.
