  • Patent number: 7880988
    Abstract: A hard disk drive which can maintain a write property at a constant level by reflecting a temperature effect during a write parameter set process even when the hard disk drive is used under a condition different from one intended during manufacturing of the disk. The hard disk drive includes a disk, a thermister and a controller. The disk stores data and the thermister measures the temperature around the disk. The controller is coupled to the thermister and selects a parameter to be optimized from parameters related to a disk write operation. The controller writes arbitrary data to a test track on the disk to obtain a first bit error rate of the test track. The controller repeatedly writes arbitrary data to at least one track adjacent to the test track indicated by as many times as an adjacent track write count is based on an associated temperature measured by the thermister to obtain a second bit error rate of the test track.
