Abstract
A write condition setting method includes a measuring step for measuring at least one of a track per inch margin, an offset margin and an on-track accuracy margin with respect to a head for each of a plurality of temperatures prior to writing data on a track of a disk, and a setting step for variably setting at least one of a write current applied to the head and an off-track slice as a write condition for each of the plurality of temperatures based on a parameter which is dependent upon temperature so that the at least one of the track per inch margin, the offset margin and the on-track accuracy margin becomes a maximum.
