METHOD AND APPARATUS FOR ENABLING COLD TEMPERATURE PERFORMANCE OF A DISK

摘要

In cold weather, the higher torque required for normal spinning operation of a spindle motor assembly (126) in a direct access storage device (100) due to the increased viscosity of the grease, is overcome by localising the heating to the spindle motor assembly (126) to reduce the viscosity of the grease, and then let a disk driven (102) self heat during and after spin-up of the spindle motor assembly (126).
