Hard disk drive, method for optimizing write parameter of hard disk drive and computer readable recording media recording the method

摘要

hard disk drive, a hard disk drive of a recording parameter optimization method and a method for performing a computer program. that the recorded recording medium is disclosed. How to optimize the recording parameters of the hard disk drive of the present invention, (a) selecting one from among the parameters of the optimization target record and relevant parameters on the disk by setting a value for any of the parameters; Step (b) writes the random data to the test track (Test Track) on the disk to obtain a first bit error rate (BER, Bit Error Rate) of the test track; (C) the number of disk adjacent the periphery of the resulting recording tracks on the basis of the temperature (ATW count, Adjacent Track Write count) by repeating the second bit error rate of the test track to record any data on at least one track adjacent to the test track, obtain; And (d) a step of setting an optimized value of the selected parameter at the second bit error rate of the first zone is part of the difference between the test tracks the value of the selected parameter is smaller than a predetermined threshold value of bit error rate (Zone) characterized in that it comprises. According to the present invention, by reflecting the effect of temperature on the process of setting the recording parameter, even if used in different temperature conditions and the production may provide a hard disk drive that can maintain the recording characteristics at a certain level.
