Abstract:
An apparatus for sensing the temperature in a computer hard disc drive and controlling operating parameters within the disc drive in response thereto, comprising:a) a thermoelectric sensor having an output sensor voltage which is variable as a function of temperature,b) an interface circuit adapted to receive the output sensor voltage from said thermoelectric sensor and adapted to generate a scaled and level-shifted analog output voltage signal,c) an analog-to-digital circuit adapted to receive said analog output signal voltage from said interface circuit and convert said analog output signal voltage into a digital signal, andd) a microcontroller which receives the digital signal from said analog-to-digital converter circuit and converts the digital signal into a temperature representative value,said microcontroller further being adapted to store said temperature values on a hard disc drive and be responsive to said stored temperature values and detection of an error condition to adjust read/write parameter settings until the error condition is ended.
