ABSTRACT:
A write precompensation amount setting method and apparatus comprise a function detecting the respective head characteristics with an electric current used at an ordinary temperature and a irregular electric current, and a function setting an optimum write precompensation amount at a low temperature according to the detected head characteristics.As a result, a write precompensation amount is corrected according to the characteristics of the normal current and the irregular current, and a write precompensation amount is determined, so that the write precompensation amount with higher accuracy than that with a conventional technique can be determined.
