Abstract

Disclosed is a method for Warming up Spindle Motor at Freezing Temperature in a Hard Disk Drive(HDD). Now, CAR-NAVIGATION system group require that HDD must work regularly under condition between 80degC to -20degC" Spindle motor of Hard Disk Drive is difficult to rotate due to hardly-stickiness of oil at -20degC condition. Therefore Hard Disk Drive cannot make spindle rotate under freezing temperature.
