ABSTRACT:
A disk drive includes a drive housing, a storage disk and a slider. The slider includes a head that magnetically interacts with the storage disk. Further, the slider includes a slider mover that moves a portion of the slider to adjust a head-to-disk spacing during operation of the disk drive. In one embodiment, the slider mover is formed from a material having a thermal coefficient of resistivity that is less than approximately 0.001/° C., such as a copper-manganese alloy, a copper-tin alloy or a gold alloy. The slider mover can be formed from a material having a negative thermal coefficient of resistivity. Further, the slider mover can be formed from a material having a resistivity that is less than approximately 15 microohm-centimeters. Additionally, the slider mover can be formed from a material having a melting point that is greater than approximately 750° C. The disk drive can include a drive circuitry and a lead that conducts electricity between the slider mover and the drive circuitry. The lead can be formed from substantially the same materials as the slider mover.
