ABSTRACT:
A disk drive, medium, and method controlling a write parameter of a disk drive are provided. The method of compensating for a write parameter, in order to control a write operation of a disk drive, can includes measuring a bit error rate in an optimum write condition and a bit error rate in a weak write condition for a head, and calculating a compensation value for a write parameter corresponding to a difference between the bit error rates in an optimum write condition and the bit error rate in the weak write condition. In a method, according to embodiments of the present invention, a compensation value alpha for compensating a write parameter for a predetermined period of time after the start of a write operation can be generated to prevent a weak write phenomenon at the beginning of the write operation.
