Abstract
According to one embodiment, an information recording device includes: a magnetic recording medium having tracks; a detector configured to detect widths of fringing phenomena that occur on both sides, in a track arrangement direction, of a track during recording on the track; and a recording controller configured to control recording so that adjacent tracks overlap with each other and that a track pitch is set at least on the basis of a smaller one of the detected fringing widths and a data read width for reading of data from the track.

An information recording device comprising:
- a magnetic recording medium having tracks;
- a detector configured to detect widths of fringing phenomena that occur on both sides, in a track arrangement direction, of a track during recording on the track;
- and
- a recording controller configured to control recording so that a part of adjacent tracks overlap with each other and that a track pitch is set at least based on a smaller one of the detected fringing widths and a data read width for reading of data from the track.
An information recording method of an information recording device which is equipped with a magnetic recording medium having tracks, comprising:
- detecting widths of fringing phenomena that occur on both sides, in a track arrangement direction, of a track during recording on the track;
- and
- controlling recording so that a part of adjacent tracks overlap with each other and that a track pitch is set at least based on a smaller one of the detected fringing widths and a data read width for reading of data from the track.
