Abstract

Disclosed is a Method of Measurement ambient temperature by Load/Unload calibration. The influence of a surrounding temperature in HDD is growing, because of HDD become high density and high performance. This invention is the one to give the function that a surrounding temperature can be measured by LOAD/UNLOAD calibration function. 2.5-inch HDD product used Load/Unload Function. So, Need to measure of the relation between Digital Analog Converter values and reverse current value before Load/Unload Function. This result has some gap according to surround temperature.
